THE PLANETOID OF PERIL

By Paul Ernst

 

Undaunted by crazy tales of an indestructible presence on Asteroid Z-40, Harley 2Q14N20 sets out alone to face and master it.

 

Harley 2Q14N20 stopped for a moment outside the great dome of the Celestial Developments Company. Moodily he stared at their asteroid development chart. It showed, as was to be expected, the pick of the latest asteroid subdivision projects: the Celestial Developments Company, established far back in 2045, would handle none but the very best. Small chance of his finding anything here!

However, as he gazed at the chart, hope came suddenly to his face, and his heart beat high under his sapphire blue tunic. There was an asteroid left for sale there--one blank space among the myriad, pink-lettered Sold symbols. Could it be that here was the chance he had been hunting so desperately?

He bent closer, to read the description of the sphere, and the hope faded gradually from his countenance. According to its orbit and location, and the spectroscopic table of its mineral resources, it was a choice planetoid indeed. Of course such a rich little sphere, listed for sale by the luxurious Celestial Developments Company, would cost far more than he could ever rake together to pay for an asteroid.

Shaking his head, he adjusted his gravity regulator to give him about a pound and a half of weight, and started to float on. Then, his lips twisting at his own absurd hopefulness, he stopped again; and after another moment of indecision turned into the archway that led to the concern's great main office. After all, it wouldn't hurt to inquire the price, even though he knew in advance it would be beyond his humble means.

* * * * *

A youngster in the pale green of the one-bar neophyte in business promptly glided toward him.

"Something for you to-day, sir?" he asked politely.

"Yes," said Harley. "I'm looking around for a planetoid; want to get a place of my own out a way from Earth. Something, you understand, that may turn out to be a profitable investment as well as furnishing an exclusive home-site. I see on your chart that you have a sphere left for sale, in the Red Belt, so I came in to ask about it."

"Ah, you mean asteroid Z-40," said the youngster, gazing with envious respect at the ten-bar insignia, with the crossed Sco drills, that proclaimed Harley to be a mining engineer of the highest rank. "Yes, that is still for sale. A splendid sphere, sir; and listed at a remarkably low figure. Half a million dollars."

"Half a million dollars!" exclaimed Harley. It was an incredibly small sum: scarcely the yearly salary of an unskilled laborer. "Are you sure that's right?"

"Yes, that's the correct figure. Down payment of a third, and the remaining two thirds to be paid out of the exploitation profits--"

* * * * *

Here the conversation was interrupted by an elderly, grey-haired man with the six-bar dollar-mark insignia of a business executive on his purple tunic. He had been standing nearby, and at the mention of asteroid Z-40 had looked up alertly. He glided to the two with a frown on his forehead, and spoke a few curt words to the neophyte, who slunk away.

"Sorry, sir," he said to Harley. "Z-40 isn't for sale."

"But your young man just told me that it was," replied Hartley, loath to give up what had begun to look like an almost unbelievable bargain.

"He was mistaken. It's not on the market. It isn't habitable, you see."

"What's wrong--hasn't it an atmosphere?"

"Oh, yes. One that is exceptionally rich in oxygen, as is true of all the spheres we handle. With a late model oxygen concentrator, one would have no trouble at all existing there."

"Is its speed of revolution too great?"

"Not at all. The days are nearly three hours long: annoying till you get used to it, but nothing like the inferior asteroids of the Mars Company where days and nights are less than ten minutes in duration."

"Well, is it barren, then? No minerals of value? No vegetation?"

"The spectroscope shows plenty of metals, including heavy radium deposits. The vegetation is as luxuriant as that of semi-tropic Earth."

"Then why in the name of Betelguese," said Harley, exasperated, "won't you sell the place to me? It's exactly what I've been looking for, and what I'd despaired of finding at my price."

"I'm forbidden to tell why it isn't for sale," said the executive, starting to float off. "It might hurt our business, reputation if the truth about that bit of our celestial properties became widely known--Oh, disintegrate it all! Why wasn't the thing erased from the chart weeks ago!"

"Wait a minute." Harley caught his arm and detained him. "You've gone too far to back out now. I'm too eager to find some such place as your Z-40 to be thrown off the subject like a child. Why isn't it for sale?"

The man tightened his lips as though to refuse to answer, then shrugged.

"I'll tell you," he said at last. "But I beg of you to keep it confidential. If some of our investors on neighboring asteroids ever found out about the peril adjoining them on Z-40, they'd probably insist on having their money back."

He led the way to a more secluded spot under the big dome, and spoke in a low tone, with many a glance over his shoulder to see if anyone were within earshot.

"Z-40 is an exceptionally fine bit of property. It is commodious; about twenty miles in diameter. Its internal heat is such that it has a delightful climate in spite of the extreme rarity of atmosphere common to even the best of asteroids. It has a small lake; in fact it has about everything a man could want. Yet, as I said, it is uninhabitable."

His voice sank still lower.

"You see, sir, there's already a tenant on that sphere, a tenant that was in possession long before the Celestial Developments Company was organized. And it's a tenant that can't be bought off or reasoned with. It's some sort of beast, powerful, ferocious, that makes it certain death for a man to try to land there."

"A beast?" echoed Harley. "What kind of a beast?"

"We don't know. In fact we hardly even know what it looks like. But from what little has been seen of it, it's clear that it is like no other specimen known to universal science. It's something enormous, some freak of animal creation that seems invulnerable to man's smaller weapons. And that is why we can't offer the place for sale. It would be suicide for anyone to try to make a home there."

"Has anyone ever tried it?" asked Harley. "Any competent adventurer, I mean?"

"Yes. Twice we sold Z-40 before we realized that there was something terribly wrong with it. Both buyers were hardy, intrepid men. The first was never heard of after thirty-six hours on the asteroid. The second man managed to escape in his Blinco Dart, and came back to Earth to tell of a vast creature that had attacked him during one of the three-hour nights. His hair was white from the sight of it, and he's still in a sanitarium, slowly recovering from the nervous shock."

Harley frowned thoughtfully. "If this thing is more than a match for one man, why don't you send an armed band with heavy atomic guns and clear the asteroid by main force?"

"My dear sir, don't you suppose we've tried that? Twice we sent expensive expeditions to Z-40 to blow the animal off the face of the sphere, but neither expedition was able to find the thing, whatever it is. Possibly it has intelligence enough to hide if faced by overwhelming force. When the second expedition failed, we gave it up. Poor business to go further. Already, Z-40 has cost us more than we could clear from the sale of half a dozen planetoids."

For a long time Harley was silent. The Company was a hard headed, cold blooded concern. Anything that kept them from selling an asteroid must be terrible indeed.

His jaw set in a hard line. "You've been honest with me," he said at length. "I appreciate it. Just the same--I still want to buy Z-40. Maybe I can oust the present tenant. I'm pretty good with a ray-pistol."

"It would be poor policy for us to sell the asteroid. We don't want to become known as a firm that trades in globes on which it is fatal to land."

"Surely my fate is none of your worry?" urged Harley.

"The asteroid," began the executive with an air of finality, "is not for--"

"Man, it's got to be!" cried Harley. Then, with a perceptible effort he composed himself. "There's a reason. The reason is a girl. I'm a poor man, and she's heiress to fabulous--Well, frankly, she's the daughter of 3W28W12 himself!" The executive started at mention of that universally known number. "I don't want to be known as a fortune hunter; and my best bet is to find a potentially rich asteroid, cheap, and develop it--incidentally getting an exclusive estate for my bride and myself far out in space, away from the smoke and bustle of urban Earth. Z-40, save for the menace you say now has possession of it, seems to be just what I want. If I can clear it, it means the fulfillment of all my dreams. With that in view, do you think I'd hesitate to risk my neck?"

"No," said the executive slowly, looking at the younger man's powerful shoulders and square-set chin and resolute eyes. "I don't think you would. Well, so be it. I'd greatly prefer not to sell you Z-40. But if you want to sign an agreement that we're released of all blame or responsibility in case of your death, you can buy it."

"I'll sign any agreement you please," snapped Harley. "Here is a down payment of a hundred and seventy thousand dollars. My name is Harley; sign 2Q14N20; unmarried--though I hope to change that soon, if I live--occupation, mining engineer, ten-bar degree; age, thirty-four. Now draw me up a deed for Z-40, and see that I'm given a stellar call number on the switchboard of the Radivision Corporation. I'll drop around there later and get a receiving unit. Good day." And, adjusting his gravity regulator to lighten his weight to less than a pound, he catapulted out the archway.

Behind him a prosaic business executive snatched a moment from a busy day to indulge in a sentimental flight of fancy. He had read once of curious old-time beings called knights, who had undertaken to fight and slay fire-eating things called dragons for the sake of an almost outmoded emotion referred to as love. It occurred to him that this brusque man of action might be compared to just such a being. He was undertaking to slay a dragon and win a castle for the daughter of 3W28W12--

The romantic thought was abruptly broken up by the numeral. It jarred so, somehow, that modern use of numbers instead of names, when thinking of sentimental passages of long ago. "The rose is fair; but in all the world there is no rose as fair as thou, my princess 3W28W12...." No, it wouldn't do.

Cursing himself for a soft-headed fool, he went to deliver a stinging rebuke to somebody for not having blocked Z-40 off the asteroid chart weeks before.

* * * * *

"Harley 2Q14N20," recited the control assistant at Landon Field. "Destination, asteroid Z-40. Red Belt, arc 31.3470. Sights corrected, flight period twelve minutes, forty-eight seconds past nine o'clock. All set, sir?"

Harley nodded. He stepped inside the double shell of his new Blinco Dart--that small but excellent quantity-production craft that had entirely replaced the cumbersome space ships of a decade ago--and screwed down the man-hole lid. Then, with his hand on the gravity bar, he gazed out the rear panel, ready to throw the lever at the control assistant's signal.

The move was unthinkingly, mechanically made. Too many times had he gone through this process of being aimed by astronomical calculation, and launched into the heavens, to be much stirred by the wonder of it. The journey to Z-40 in the Dart was no more disquieting than, a century and a half ago, before the United States had fused together into one vast city, a journey from Chicago to Florida would have been in one of the inefficient gasoline-driven vehicles of that day.

All his thoughts were on his destination, and on a wonder as to what could be the nature of the thing that dwelt there.

He had just come from the sanitarium where the man who'd bought Z-40 before him was recovering from nervous exhaustion. He'd gone there to try to get first hand information about the creature the executive at the Celestial Developments Company had talked so vaguely of. And the tale the convalescent had told him of the thing on the asteroid was as fantastic as it was sketchy.

A tremendous, weirdly manlike creature looming in the dim night--a thing that seemed a part of the planetoid itself, fashioned from the very dirt and rock from which it had risen--a thing immune to the ray-pistol, that latest and deadliest of man-made small-arms--a thing that moved like a walking mountain and stared with terrible, stony eyes at its prey! That was what the fellow said he had faintly made out in the darkness before his nerves had finally given way.

He had impressed Harley as being a capable kind of a person, too; not at all the sort to distort facts, nor to see imaginary figures in the night.

There was that matter of the stone splinter, however, which certainly argued that the wan, prematurely white-haired fellow was a little unbalanced, and hence not to be believed too implicitly. He'd handed it to Harley, and gravely declared it to be a bit of the monster's flesh.

"Why, it's only a piece of rock!" Harley had exclaimed before he could check himself.

"Did you ever see rock like it before?"

Turning it over in his hands, Harley had been forced to admit that he never had. It was of the texture and roughness of granite, but more heavily shot with quartz, or tridymite than any other granite he'd ever seen. It had a dull opalescent sheen, too. But it was rock, all right.

"It's a piece of the thing's hide," the man had told him. "It flaked off when it tried to pry open the man-hole cover of ray Dart. A moment after that I got Radivision arc directions from London Field, aimed my sights, and shot for Earth. It was a miracle I escaped."

"But surely your ray-pistol--" Harley had begun, preserving a discreet silence about the man's delusion concerning the stone splinter.

"I tell you it was useless as a toy! Never before have I seen any form of life that could stand up against a ray-gun. But this thing did!"

This was another statement Harley had accepted with a good deal of reservation. He had felt sure the weapon the man had used had a leak in the power chamber, or was in need of recharging, or something of the kind. For it had been conclusively proved that all organic matter withered and burned away under the impact of the Randchron ray.

Nevertheless, discounting heavily the convalescent's wild story, only a fool would have clung to a conviction that the menace on Z-40 was a trivial one. There was something on that asteroid, something larger and more deadly than Harley had ever heard of before in all his planetary wanderings.

He squared his shoulders. Whatever it was, he was about to face it, man against animal. He was reasonably certain his ray-gun would down anything on two legs or ten. If it didn't--well, there was nothing else that could; and he'd certainly provide a meal for the creature, assuming it ate human flesh....

A mechanic tapped against the rear view panel to recall his wandering attention. The control assistant held up his hands, fingers outspread, to indicate that there were ten seconds left.

Harley's hand went to his throat, where was hung a locket--a lovely but useless trinket of the kind once much worn by Earth women--and his fingers tightened tenderly on it. It had belonged to Beatrice 3W28W12's great-great-grandmother, and Beatrice had given it to him as a token.

"With luck, my dear," he whispered aloud. "With luck...."

There was a slight vibration. He threw the gravity bar over to the first notch. Earth dropped, plummet-like, away from him. He pushed the bar to the limit leg; and, at a rate of hundreds of miles a second, was repelled from Earth toward Z-40, and the thing that skulked there.

* * * * *

With a scarcely perceptible jar, he landed on the small sphere that, he hoped, was to be his future home. Before opening his man-hole lid, he went from panel to panel of the Dart and cautiously reconnoitered. He had elected to land beside the little lake that was set like a three hundred-acre gem on the surface of Z-40, and it was more than possible that the enemy had its den nearby.

However, a careful survey of the curved landscape in all directions failed to reveal a glimpse of anything remotely threatening. He donned his oxygen concentrator--in appearance a simple tube of a thing, projecting about six inches above his forehead, and set in a light metal band that encircled his head. Adjusting his gravity regulator so he wouldn't inadvertently walk clear off into empty space--he calculated his weight would be less than a twentieth of an ounce here--he stepped out of the Dart and gazed around at the little world.

Before him was the tiny lake, of an emerald green hue in the flashing sunlight. Around its shores, and covering the adjacent, softly rolling countryside as far as eye could reach, was a thick growth of carmine-tinted vegetation: squat, enormous-leaved bushes; low, sturdy trees, webbed together by innumerable vines. To left and right, miniature mountains reared ragged crests over the abbreviated horizon, making the spot he was in a peaceful, lovely valley.

He sighed. There was everything here a man could wish for--provided he could win it! Loosening his ray-pistol in its holster, he started to walk slowly around the lake to choose a site for the house he intended to build. On the opposite shore he found a place that looked suitable.

A few yards back from the water's edge, curling in a thick crescent like a giant sleeping on its side, was a precipitous outcropping of rock; curious stuff, rather like granite, that gleamed with dull opalescence in the brilliant sunlight. With that as a sort of natural buttress behind the house, and with the beautiful lake as his front dooryard, he'd have a location that any man might envy.

He returned to his Dart, hopped back across the lake in it, and unloaded his Sco drill[1]. With this he planned to sink a shaft that would serve in the future as the cellar for his villa, and in the present as an entrenchment against danger.

But now the swift night of Z-40 was almost upon him. The low slant of the descending sun warned him that he had less than ten minutes of light left, until the next three-hour day should break over the eastern rim. He placed the drums and the flexible hose of the Sco drill so that he could begin operations with it as soon as the dawn broke, and started to walk toward the precipitous outcropping of quartziferous stone immediately behind the home-site he had picked. He would climb to the top of this for a short look around, and then return to the Dart--in which double-hulled, metal fortress he thought he would be safe from anything.

* * * * *

He had almost reached the rock outcropping when the peculiarities of its outline struck him anew. He'd already observed that the craggy mound rather resembled a sleeping, formless giant. The closer he got to it the more the resemblance was heightened and the greater grew his perplexity.

It sprang straight up from the carmine underbrush, like a separate heap of stone cast there by some mighty hand. One end of it tapered down in a thick ridge; and this ridge had a deep, horizontal cleft running along it which made it appear as though it were divided into two leglike members. In the center the mound swelled to resemble a paunchy trunk with sagging shoulders. This was topped by a huge, nearly round ball that looked for all the world like a head. There were even rudimentary features. It was grotesque--one of those freak sculptures of nature, Harley reflected, that made it seem as though the Old Girl had a mind and artistic talent of her own.

He scrambled through the brush till he reached that part of the long mound that looked like a head. There, as the sun began to stream the red lines of its descent over the sky, he prepared to ascend for his view of the surrounding landscape.

He'd got within twenty feet of the irregular ball, and had adjusted his gravity regulator to enable him to leap to its top, when he stopped as abruptly as though he had been suddenly paralyzed. Over the two deep pits that resembled nostrils in the grotesque mask of a face he thought he had observed a quiver. The illusion had occurred in just the proper place for an eyelid. It was startling, to say the least.

"I'm getting imaginative," said Harley. He spoke aloud as a man tends to do when he is alone and uneasy. "I'd better get a tighter grip on my nerves, or--good God!"

Coincident with the sound of his voice in the thin, quiet air, the huge stumps that looked like legs stirred slightly. A tremor ran through the entire mass of rock. And directly in front of Harley, less than twenty feet from where he stood, a sort of half-moon-shaped curtain of rock slid slowly up to reveal an enormous, staring eye.

Frozen with a terror such as he had never felt before in a life filled with adventure, scarce breathing, Harley glared at the monstrous spectacle transpiring before him. A hill was coming to life, A granite cliff was growing animate. It was impossible, but it was happening.

The half-moon curtains of rock that so eerily resembled eyelids, blinked heavily. He could hear a faint rasping like the rustle of sandpaper, as they did so. One of the great leg stumps moved distinctly, independent of the other one. Three columnar masses of rock--arms, or tentacles, with a dozen hinging joints in each--slowly moved away from the parent mass near the base of the head, and extended toward the Earth man.

Still in his trance, with his heart pounding in his throat till he thought it would burst, Harley watched the further awful developments. The eyelids remained opened, disclosing two great, dull eyes like poorly polished agates, which stared expressionlessly at him. There was a convulsion like a minor earthquake, and the mass shortened and heightened its bulk, raising itself to a sitting posture. The three hinged, irregular arms suddenly extended themselves to the full in a thrust that barely missed him. They were tipped, those arms, with immense claws, like interlocking, rough-hewn stone fingers. They crashed emptily together within a few feet of Harley. Then, and not till then, did the paralysis of horror loose its grip on the human.

He tore his ray-pistol from its holster and pointed it at the incredible body. An angry, blue-green cone of light leaped from the muzzle, and played over the mighty torso. Nothing happened. He squeezed the trigger back to the guard. The blue-green beam increased in intensity, and a crackling noise was audible. Under that awful power the monster should have disappeared, dissolved to a greasy mist. But it didn't.

The light beam from the ray-gun died away. The power was exhausted. It was only good for about ten seconds of such an emergency, full-force discharge, after which it must be re-charged again. The ten seconds were up. And the gigantic creature against which it had been directed had apparently felt no injury from a beam that would have annihilated ten thousand men.

The now useless ray-pistol slipped from his limp fingers. Stupefied with horror at the futility of the deadly Randchron ray against this terrible adversary, he stood rooted to the spot. Then the thing reached for him again; and his muscles were galvanized to action--to instinctive, stupid, reasonless action.

Screaming incoherently, mad with horror of the stone claws that had clutched at him, he turned and ran. In great leaps he bounded away from the accursed lake and made for the taller trees and thicker vegetation at a distance from the shore. It was the worst thing he could have done. There was a chance that he could have reached his Dart, had he thought of it, and soared aloft out of reach. But he thought of nothing. All he wanted to do, in that abysmal fear that can still make a mindless animal out of a civilized man, was to run and hide--to get away from the fearful monster that had risen up to glare at him with those stony, pitiless eyes, and to reach for him with two-fingered bands like grinding rock vises.

* * * * *

Just as the sun fell below the rim of the asteroid, plunging it into a darkness only faintly relieved by the light of the stars, he crashed into the deeper underbrush. A trailing creeper tripped him in his mad flight. He fell headlong, to lie panting, sobbing for breath, in the thick carpet of blood-colored moss.

Behind him, from the direction of the lake, he heard a sudden clangor as of rock beating against metal. This endured only a short time. Then the solid ground beneath him shook slightly, and an appalling crash of trees and underbrush to the rear told him that the stone colossus was on his trail.

He leaped to his feet and continued his great bounds over the sharply curved surface of the asteroid, banging against tree trunks, bruising himself against stones, falling in the darkness to rise again and flee as before in a mad attempt to distance the crashing sound of pursuit behind him.

Then he felt himself writhing in thin air as his flying course took him over the edge of a cliff. Down, down he fell, to land in a dense bed of foliage far below. Something hit his head with terrific force. Pinwheels of light flashed before his eyes, to fade into velvety nothingness....

* * * * *

Slowly, uncertainly he wavered back to consciousness. For a moment he was aware of nothing save that he was lying on some surface that was jagged and uncomfortable, and that it was broad daylight. He opened his eyes, and saw that he was reclining, across a springy bed formed of the top of a tree. Ahead of him loomed a cliff about a hundred feet high.

Remembrance suddenly came to him. The unreasoning rush through the underbrush. The nightmare creature lumbering swiftly after him. The fall over the cliff into the top of this tree.

With a cry, he sat up, expecting to see the stone giant nearby and poised to leap. But it was nowhere in sight; nor, listen as intently as he would, could he hear the sounds of its crashing path through the brush. Somehow, for the moment at least, he had been saved. Perhaps his disappearance over the cliff edge had thrown it off his track.

He became aware of the fact that it was difficult for him to breathe. His lungs were heaving in a vain effort to suck in more oxygen, and his tongue felt thick as though he were being strangled. Then he saw that his oxygen concentrator had been knocked from his head when he fell, and was dangling from a limb several feet away. It was almost out of breathing range. Had it fallen on through the branches to the ground he would have died, in his unconsciousness, in the rarified atmosphere. He reached for it; settled the band around his head again.

After once more listening and peering around to make sure the rock colossus was not about, he descended the tree that had saved his life, and began to walk in the direction he judged the lake to be. He would get into his Dart, cruise aloft out of harm's way, and perhaps think up some effective course of action.

* * * * *

He was thinking clearly, now. And, in the glare of daylight, no longer an unreasoning animal fleeing blindly over a dim-lit foreign sphere, he was unable to understand his panic of the night. Afraid? Of course he had been afraid! What man wouldn't have been at sight of that monstrous thing? But that he, Harley 2Q14N20, should have lost his head completely and gone plunging off into the brush like that, seemed unbelievable. To the depths of his soul he felt ashamed. And to his own soul he made the promise that he would wipe out, in action, that hour of cowardice.

As he wound his way through the squat, carmine forest, he tried to figure out the nature of the thing that had crashed balefully after him in the black hours.

It had seemed made of rock--a giant, primitive stone statue imbued with life. But it was impossible that it should really be fashioned of rock. At least it ought to be impossible. Rock is inorganic, inanimate. It simply couldn't have the spark of life in it. Harley had seen many strange creations, on many strange planets, but never had he seen inorganic mineral matter endowed with animation. Nor had anyone else.

Yet the thing looked as though made of stone. Of some peculiar, quartz-suffused granite--proving that the wan, white-haired man he had talked to in the sanitarium had not been mad at all, but only too terribly sane. The creature's very eyes had had a stony look. Its eyelids had rasped like stone curtains rubbing together. Its awful, two-fingered hands, or claws, had ground together like stones rubbing.

Was it akin to the lizards, the cold-blooded life of Earth? Was this rocky exterior merely a horny shell like that of a turtle? No. Horn is horn and rock is rock. The two can't be confused.

The only theory Harley could form was that the great beast was in some strange way a link between the animal and the mineral kingdoms. Its skeletal structure, perhaps, was silicate in substance, extending to provide an outside covering that had hardened into actual stone, while forming an interior support to flesh that was half organic, half inorganic matter. Some such silicate construction was to be found in the sponge, of Earth. Could this be a gigantic relative of that lowly creature? He did not know, and couldn't guess. He wasn't a zoologist. All he knew was that the thing appeared to be formed of living, impregnable stone. He knew, also, that this fabulous creature was bent on destroying him.

At this point in his reflections, the glint of water came to his eyes between the tree trunks ahead of him. He had come back to the lake.

* * * * *

For moments he stood behind one of the larger trees on the fringe and searched around the shore for sight of the rock giant. It was nowhere in evidence. Rapidly he advanced from the forest and ran for the Dart. From a distance it appeared to be all right: but as he drew near a cry rose involuntarily to his lips.

In a dozen places the double hull of the little space craft was battered in. The man-hole lid was torn from its braces and bent double. The glass panels, unbreakable in themselves, had been shoved clear into the cabin; their empty sash frames gaped at Harley like blinded eyes. Never again would that Blinco Dart speed through the heavens!

He went to the spot where he had left his Sco drill, and a further evidence of the thing's cold blooded ferocity was revealed. The intricate mechanism had been wrenched into twisted pieces. The drums were battered in and the flexible hose lengths torn apart in shreds. The inventor himself couldn't have put it in working order again.

He was hopelessly trapped. He had no means of fighting the colossus. He had no way of escaping into space, nor of returning to Earth and trying to raise a loan that would allow him to come back here with men and atomic guns. He hadn't even a way of intrenching himself in the ground against the next attack.

For an instant his hair prickled in a flash of the blind panic that had seized him a few hours before. With a tremendous effort of will he fought it down. This--the destruction of his precious Dart and drill--was the result of one siege of insensate fear. If he succumbed to another one he might well dash straight into the arms of death. He sank to the ground and rested his chin on his fist, concentrating all his intellect on the hopeless problem that faced him.

The surface of Z-40 was many square miles in extent. But, if he tried to hide himself, he knew it was only a question of time before he would be hunted down. The asteroid was too tiny to give him indefinite concealment. Flight, then, was futile.

But if he didn't try to conceal himself in the sparse forest lands, it meant that he must stay to face the monster at once--which was insanity. What could he do, bare-handed, against that thirty-foot, three-tentacled, silicate mass of incredible life!

It was useless to run, and it was madness to stay and confront the thing. What, then, could he do? The sun had slid down the sky and the red of another swift dusk was heralding the short night before he shook his head somberly and gave the fatal riddle up.

He rose to his feet, intending to make his way back to the concealment--such as it was--of the forest. It might be that he could find safety in some lofty treetop till day dawned again. Then he stopped, and listened. What was that?

From far away to the left he could hear faint sounds of some gargantuan stirring. And, coincident with the flickering out of the last scrap of sunlight, a distant crashing came to his ears as an enormous body smashed like an armored ship through trees and thorn bushes and trailing vines. The rock thing had found his trail and was after him again.

* * * * *

A second time Harley fled through the dim-lighted night, stumbling over boulders and tripping on creepers. But this time his flight was not that of panic. Frightened enough, he was; but his mind was working clearly as he leaped through the forest away from the source of the crashing.

The first thing he noted was that though--as far as his ears could inform him--he was managing to keep his lead, he wasn't outdistancing his horrible pursuer by a yard. Dark though the night was, and far away as he contrived to keep himself, the colossus seemed to cling to his trail as easily as though following a well-blazed path.

He climbed a tree, faced at right angles to the course he had pursued, and swung for the next tree. It was a long jump. But desperation lent abnormal power to his muscles, and the gravity regulator adjusted to extremely low pitch, was a great help. He made it safely. Another swinging leap into the dark, to land sprawling in a second tree; a third; a fourth. Finally be crouched in a tangle of boughs, and listened. He was a quarter of a mile from the point where he had turned from his first direction. Perhaps this deviation would throw the rock terror off.

It didn't. He heard the steady smashing noise stop. For an instant there was a silence in the darkness of the asteroid that was painful. Then the crashing was resumed, this time drawing straight toward where he was hidden. Somehow the thing had learned of his change of direction.

He continued his flight into the night, his eyes staring glassily into the darkness, his expression the ghastly one of a condemned man. And as he fled the crashing behind him told how he was followed--easily infallibly, in spite of all his twisting and turning and efforts at concealment. What hellish intelligence the monster must possess!

He ran for eternities. He ran till his chest was on fire, and the sobbing agony of his breathing could be heard for yards. He ran till spots of fire floated before his eyes and the blood, throbbing in his brain, cut out the noise of the devilish pursuit behind him. At long last his legs buckled under him, and he fell, to rise no more.

He was done. He knew it. His was the position of the hunted animal that lies panting, every muscle paralyzed with absolute exhaustion, and glares in an agony of helplessness at the hunter whose approach spells death.

The crashing grew louder. The tremor of the ground grew more pronounced as the vast pursuer pounded along with its tons and tons of weight. Harley gazed into the blackness back along the way he had come, his eyes sunk deep in the hollows fatigue had carved in his face, and waited for the end. The dark night darkened still more with the approach of another swift, inexorable dawn.

There was a terrific rending of tree trunks and webbed creepers. Dimly in the darkness he could see something that towered on a level with the tallest trees, something that moved as rapidly and steadily as though driven by machinery. Fear so great that it nauseated him, swept over him in waves; but he could not move.

The first grey smear of dawn appeared in the sky. In the ghostly greyness he got a clearer and clearer sight of the monster. He groaned and cowered there while it approached him--more slowly now, eyeing him with staring, stony orbs in which there was no expression of any kind, of rage or bate, of curiosity or triumph.

Great stumps of legs, with no joints in them, on which the colossus stalked like a moving stone tower--a body resembling an enormous boulder carved by an amateurish hand to portray the trunk of a human being--a craggy sphere of rock for a head, set directly atop the deeply riven shoulders--a face like the horrible mask of an embryonic gargoyle--a mouth that was simply a lipless chasm that opened and closed with the sound of rocks grinding together in a slow-moving glacier--the whole veiled thinly by trailing lengths of snapped vines, great shattered tree boughs, bushes, all uprooted in its stumping march through the forest! Harley closed his eyes to shut out the sight. But in spite of himself they flashed open again and stared on, as though hypnotized by the spectacle they witnessed.

* * * * *

The grey of dawn lightened to the first rose tint of the rising sun. As though stung to action by the breaking of day, the thing hastened its ground-shaking pace. With one last stride, it came to Harley's side and loomed far above, the unwinking eyes glaring down at him.

The three arms, hinged at equidistant points at the base of the horrible head, slowly lowered toward his prostrate form. There was a grating noise as the creature hinged in the middle and bent low, bringing its enormous, staring eyes within two yards of his face.

One of its hands closed over his leg, tentatively, experimentally, as though to ascertain of what substance he was made. He cried aloud as the rock vise, like a gigantic lobster claw, squeezed tight. The thing drew back abruptly. Then the chasm of its mouth opened a little, for all the world as though giving vent to soundless, demoniac laughter. All three of the vise-like hands clamped over him--lightly enough, considering their vast size, and intimating that the colossus did not mean to kill him for a moment or two--but so cruelly that his senses swam with the pain of it.

He felt the grip relax. The vast stone pincers were lifted from him; slithered to the ground beside him.

The first blinding rays of the sun were beating straight on the colossal figure, which glittered fantastically, like a huge splintered opal, in their brilliance.

It glared down at Harley. The abyss of a mouth opened as though again giving vent to silent, infernal laughter. Then, with the noise of a landslide, the giant form settled slowly to the ground. The rock half-moons of curtains dropped over the expressionless, dull eyes. The whole great figure quivered, and grew still. It lay without movement, stretched along the ground like a craggy, opalescent hill.

* * * * *

Dazed, stunned by such fantastic behavior, Harley struggled wearily to his feet. He had been a dead man as surely as though shot with a ray-gun. One twitch of those terrible rock pincers would have broken him in two pieces. It had seemed as though that deadly twitch were surely forthcoming. And then the thing had released him--and had lain down to go to sleep! Or was it asleep?

He took a few slow steps away from it, expecting to see the three great tentacles flash out to capture him as a cat claws at a mouse that thinks it is escaping. The arms didn't move. Astounding as it was, Harley was free to run away if he chose. Why was that?

A hint of a clue to the creature's action began to unfold in his mind. When he had first laid eyes on it, in daylight, it was asleep. It had not pursued him during the preceding day, which argued that again it was asleep. And now, with the first touch of dawn, it was once more quiet, immobile.

The answer seemed to be that it was entirely nocturnal; that for some obscure, unguessable reason sunlight induced in it a state of suspended animation. It seemed an insane theory, but no other surmise was remotely reasonable.

But if it were invariably sunk in a coma during daylight, why had it delayed killing him just a moment ago? Its every act indicated that it possessed intelligence of a high order. It was more than probable that it realized its limitation--why hadn't it acted in accordance with that realization?

On thinking it over, he believed he had the answer to that, too. He remembered the way the gaping mouth had seemed to express devilish mirth. The thing was playing with him. That was all. It had saved him for another night of hopeless flight and infallible trailing through the forests of Z-40.

He gazed at the monster in a frenzy of impotent rage and fear. If only he could kill it somehow in its sleep! But he couldn't. In no way could he harm it. Secure in its silicate covering, it was impervious to his wildest attempts at destruction. And it knew it, too; hadn't it laughed just before sinking down to slumber through the asteroidal day?

With his Sco drill he might have pierced that silicon dioxide armor till he reached the creature's gritty flesh. Then he could have used his ray-pistol, possibly disintegrating all its vitals and leaving only an empty rock shell sprawling hugely there in the trampled underbrush.

But he had neither drill nor pistol. The one had been wrecked by the monster; the other he had dropped in his madness of fright, after completely exhausting its power chamber.

Half crazed by the hopelessness of his plight, he paced up and down beside the great length of animated stone. Trapped on an asteroid--utterly unarmed--alone with the most pitiless, invulnerable creation Nature had placed in a varied universe! Could Hell itself have devised a more terrible fate?

Shuddering, he turned away. He had some two and a half hours of grace, before the sun should set again and darkness release the colossus from its torpor. There was only one thing he could do: place the diameter of the sphere between the thing and himself, and try to exist through another night of terror.

His hands went to his belt to adjust the gravity regulator strapped about his waist. By reducing his weight to an ounce or two, he could make the long journey possible for his fatigue-numbed muscles--

His hands clenched into fists, and his breath whistled between his set teeth as a wild hope came to him. The touch of the regulator had brought inspiration. A way to defeat the gigantic creature stretched on the ground beside him! A way to banish it forever from the surface of this lovely little world where all was perfect but the monstrous thing with which it was cursed!

* * * * *

Trembling with the reaction wrought in him by the faint glow of hope, he began to race toward the lake and his wrecked Blinco Dart. It wasn't hard to find the way; the rock giant had left a trail as broad as a road; trees broken off like celery stalks, bushes smashed flat, tracks that looked like shallow wells sunk into the firm ground. Fifty yards to a step, he leaped along this path, praying that one object, just one bit of machinery in the Dart had escaped the general wreckage.

Arrived at the little shell at last, he was forced to pause a moment and compose himself before he could step into the battered interior. Everything hinged on this one final chance!

Drawing a long breath, he entered the cabin and made his way to the stern repellor. A groan escaped his lips. It was ruined. Evidently the thing had reached in the man-hole opening with one of its three mighty tentacles, and, with sure instinct, had fastened its stone claws on the repellor housing. At any rate, it was ground to bits. But--there was the bow repellor.

He went to that, and the flame of hope came back to his eyes. It was untouched! He threw back the housing to make sure. Yes, the inter-sliding series of plates, that reversed or neutralized gravitational attraction at a touch, were in alignment.

He bent to the task of disconnecting it from the heavy bed-plate to which it was bolted, his fingers flying frenziedly. Then back to the torpid colossus he hurried, clutching the precious repellor tight in his arms lest he should drop it, walking carefully lest he should fall with it.

There he was faced by a new difficulty that at first seemed insurmountable. How could he fasten the repellor to that great, impenetrable, opalescent bulk?

A second time he bounded back toward the Dart, to return with the heavy bow and stern bed-plates from its hull.

* * * * *

Once more the orange ball of the sun was sinking low. The terrible brevity of those three-hour days! He had less than ten minutes, Earth time, in which to work.

One of the thing's arms, or tentacles, was pointing out away from the parent mass. It was twice the diameter of his body, and was ponderously heavy; but by rigging a fulcrum and lever device, with a stone as the fulcrum and a tough log as the lever, he managed to raise it high enough to thrust one of the bed-plates under it. The other massive metal sheet he laid across the top.

The lower rim of the sun touched the horizon. A tremor ran through the colossus. In frantic haste, racing against the flying seconds, Harley clamped the two plates tight against the columnar tentacle with four long hull-bolts from the Dart. He set the repellor in position on the top bed-plate, and began to fasten it down.

He felt another tremor run through the stone column on which he was squatting. With a rasping sound, one of the half-moon rock-curtains the thing had for eyelids blinked open and shut. He shot the last bolt into place and tightened it.

The stone claws, just behind which he had fastened the repellor, ground savagely shut. The great tentacle began to lift, and carried him with it--toward the chasm of a mouth. That chasm opened wide....

Harley straightened up and jumped for the ground. As he jumped, he kicked the repellor control bar hard over.

There was a shrieking of wind as though all the hurricanes in the universe were battling each other. He felt himself turned over and over, buffeted, torn at, in a mad aerial whirlpool. The whirlpool calmed as the abruptly created vacuum, caused by the monster's rapid drive upward, passed after it into space. Far overhead there was one fleeting glimpse of a pinpoint of dull opalescence reflecting the rays of the dying sun. Then the pinpoint disappeared in fathomless space. With his gravity regulator adjusted to the point where it almost neutralized his weight, he fell slowly back toward the ground....

* * * * *

Almost immediately after he had landed in the darkness that blanketed the surface of the planetoid, a big space yacht settled down near him. A searchlight bored a hole in the blackness, to bathe him in cold light. Down the beam came a band of men from Earth, pushing atomic cannon and gazing apprehensively about them. In the lead was an elderly man with the six-bar dollar-mark insignia of a business executive on his purple tunic.

He hastened to Harley's side. Harley only dimly heard what he said. Something to the effect that the man had been worried after selling the fatal asteroid. Had got in touch with the Radivision Corporation and learned that this call number was dead. Had come with men and big guns to rescue him, if it wasn't too late, and take him back to Earth. Had cruised for half an hour before locating him. "I've been calling myself a murderer ever since I let you have Z-40, Mr. 2Q14N20," he concluded. "I was sure we'd get here only to find you'd been killed. But I see you've managed to escape from the creature so far--though by the look of you, it must have been a narrow shave."

At this Harley shook off some of the gathering dizziness that hazed his mind. He threw back his shoulders. "Managed to escape? I did better than that. I got rid of the thing forever! Yes, I'll return to Earth with you, but only because I need a new Blinco Dart. I'm coming back to Z-40 at once. Perfect little paradise, now that I've got rid of that--animated--rock pile--"

The belated rescuers caught him as he collapsed.

[Footnote 1: This implement, invented by Blansco 9X247A in 2052, is not so much a "drill" as a compressor. It is somewhat superficially defined in the Universal Dictionary, 2061 edition, as "a portable mechanism which, by alternating gaseous blasts of extreme heat and cold, breaks down the atoms of inorganic matter, causing them to collapse together in dense compression." Thus a cubic yard of earth can be reduced in size, in a few moments, to a pebble no larger than a pea; which pebble would weigh, on Earth, close to a ton.]

THE JUPITER WEAPON

By CHARLES L. FONTENAY

 

He was a living weapon of destruction--immeasurably powerful, utterly invulnerable. There was only one question: Was he human?

 

Trella feared she was in for trouble even before Motwick's head dropped forward on his arms in a drunken stupor. The two evil-looking men at the table nearby had been watching her surreptitiously, and now they shifted restlessly in their chairs.

Trella had not wanted to come to the Golden Satellite. It was a squalid saloon in the rougher section of Jupiter's View, the terrestrial dome-colony on Ganymede. Motwick, already drunk, had insisted.

A woman could not possibly make her way through these streets alone to the better section of town, especially one clad in a silvery evening dress. Her only hope was that this place had a telephone. Perhaps she could call one of Motwick's friends; she had no one on Ganymede she could call a real friend herself.

Tentatively, she pushed her chair back from the table and arose. She had to brush close by the other table to get to the bar. As she did, the dark, slick-haired man reached out and grabbed her around the waist with a steely arm.

Trella swung with her whole body, and slapped him so hard he nearly fell from his chair. As she walked swiftly toward the bar, he leaped up to follow her.

There were only two other people in the Golden Satellite: the fat, mustached bartender and a short, square-built man at the bar. The latter swung around at the pistol-like report of her slap, and she saw that, though no more than four and a half feet tall, he was as heavily muscled as a lion.

His face was clean and open, with close-cropped blond hair and honest blue eyes. She ran to him.

"Help me!" she cried. "Please help me!"

He began to back away from her.

"I can't," he muttered in a deep voice. "I can't help you. I can't do anything."

* * * * *

The dark man was at her heels. In desperation, she dodged around the short man and took refuge behind him. Her protector was obviously unwilling, but the dark man, faced with his massiveness, took no chances. He stopped and shouted:

"Kregg!"

The other man at the table arose, ponderously, and lumbered toward them. He was immense, at least six and a half feet tall, with a brutal, vacant face.

Evading her attempts to stay behind him, the squat man began to move down the bar away from the approaching Kregg. The dark man moved in on Trella again as Kregg overtook his quarry and swung a huge fist like a sledgehammer.

Exactly what happened, Trella wasn't sure. She had the impression that Kregg's fist connected squarely with the short man's chin before he dodged to one side in a movement so fast it was a blur. But that couldn't have been, because the short man wasn't moved by that blow that would have felled a steer, and Kregg roared in pain, grabbing his injured fist.

"The bar!" yelled Kregg. "I hit the damn bar!"

At this juncture, the bartender took a hand. Leaning far over the bar, he swung a full bottle in a complete arc. It smashed on Kregg's head, splashing the floor with liquor, and Kregg sank stunned to his knees. The dark man, who had grabbed Trella's arm, released her and ran for the door.

Moving agilely around the end of the bar, the bartender stood over Kregg, holding the jagged-edged bottleneck in his hand menacingly.

"Get out!" rumbled the bartender. "I'll have no coppers raiding my place for the likes of you!"

Kregg stumbled to his feet and staggered out. Trella ran to the unconscious Motwick's side.

"That means you, too, lady," said the bartender beside her. "You and your boy friend get out of here. You oughtn't to have come here in the first place."

"May I help you, Miss?" asked a deep, resonant voice behind her.

She straightened from her anxious examination of Motwick. The squat man was standing there, an apologetic look on his face.

She looked contemptuously at the massive muscles whose help had been denied her. Her arm ached where the dark man had grasped it. The broad face before her was not unhandsome, and the blue eyes were disconcertingly direct, but she despised him for a coward.

"I'm sorry I couldn't fight those men for you, Miss, but I just couldn't," he said miserably, as though reading her thoughts. "But no one will bother you on the street if I'm with you."

"A lot of protection you'd be if they did!" she snapped. "But I'm desperate. You can carry him to the Stellar Hotel for me."

* * * * *

The gravity of Ganymede was hardly more than that of Earth's moon, but the way the man picked up the limp Motwick with one hand and tossed him over a shoulder was startling: as though he lifted a feather pillow. He followed Trella out the door of the Golden Satellite and fell in step beside her. Immediately she was grateful for his presence. The dimly lighted street was not crowded, but she didn't like the looks of the men she saw.

The transparent dome of Jupiter's View was faintly visible in the reflected night lights of the colonial city, but the lights were overwhelmed by the giant, vari-colored disc of Jupiter itself, riding high in the sky.

"I'm Quest Mansard, Miss," said her companion. "I'm just in from Jupiter."

"I'm Trella Nuspar," she said, favoring him with a green-eyed glance. "You mean Io, don't you--or Moon Five?"

"No," he said, grinning at her. He had an engaging grin, with even white teeth. "I meant Jupiter."

"You're lying," she said flatly. "No one has ever landed on Jupiter. It would be impossible to blast off again."

"My parents landed on Jupiter, and I blasted off from it," he said soberly. "I was born there. Have you ever heard of Dr. Eriklund Mansard?"

"I certainly have," she said, her interest taking a sudden upward turn. "He developed the surgiscope, didn't he? But his ship was drawn into Jupiter and lost."

"It was drawn into Jupiter, but he landed it successfully," said Quest. "He and my mother lived on Jupiter until the oxygen equipment wore out at last. I was born and brought up there, and I was finally able to build a small rocket with a powerful enough drive to clear the planet."

She looked at him. He was short, half a head shorter than she, but broad and powerful as a man might be who had grown up in heavy gravity. He trod the street with a light, controlled step, seeming to deliberately hold himself down.

"If Dr. Mansard succeeded in landing on Jupiter, why didn't anyone ever hear from him again?" she demanded.

"Because," said Quest, "his radio was sabotaged, just as his ship's drive was."

"Jupiter strength," she murmured, looking him over coolly. "You wear Motwick on your shoulder like a scarf. But you couldn't bring yourself to help a woman against two thugs."

He flushed.

"I'm sorry," he said. "That's something I couldn't help."

"Why not?"

"I don't know. It's not that I'm afraid, but there's something in me that makes me back away from the prospect of fighting anyone."

Trella sighed. Cowardice was a state of mind. It was peculiarly inappropriate, but not unbelievable, that the strongest and most agile man on Ganymede should be a coward. Well, she thought with a rush of sympathy, he couldn't help being what he was.

* * * * *

They had reached the more brightly lighted section of the city now. Trella could get a cab from here, but the Stellar Hotel wasn't far. They walked on.

Trella had the desk clerk call a cab to deliver the unconscious Motwick to his home. She and Quest had a late sandwich in the coffee shop.

"I landed here only a week ago," he told her, his eyes frankly admiring her honey-colored hair and comely face. "I'm heading for Earth on the next spaceship."

"We'll be traveling companions, then," she said. "I'm going back on that ship, too."

For some reason she decided against telling him that the assignment on which she had come to the Jupiter system was to gather his own father's notebooks and take them back to Earth.

* * * * *

Motwick was an irresponsible playboy whom Trella had known briefly on Earth, and Trella was glad to dispense with his company for the remaining three weeks before the spaceship blasted off. She found herself enjoying the steadier companionship of Quest.

As a matter of fact, she found herself enjoying his companionship more than she intended to. She found herself falling in love with him.

Now this did not suit her at all. Trella had always liked her men tall and dark. She had determined that when she married it would be to a curly-haired six-footer.

She was not at all happy about being so strongly attracted to a man several inches shorter than she. She was particularly unhappy about feeling drawn to a man who was a coward.

The ship that they boarded on Moon Nine was one of the newer ships that could attain a hundred-mile-per-second velocity and take a hyperbolic path to Earth, but it would still require fifty-four days to make the trip. So Trella was delighted to find that the ship was the Cometfire and its skipper was her old friend, dark-eyed, curly-haired Jakdane Gille.

"Jakdane," she said, flirting with him with her eyes as in days gone by, "I need a chaperon this trip, and you're ideal for the job."

"I never thought of myself in quite that light, but maybe I'm getting old," he answered, laughing. "What's your trouble, Trella?"

"I'm in love with that huge chunk of man who came aboard with me, and I'm not sure I ought to be," she confessed. "I may need protection against myself till we get to Earth."

"If it's to keep you out of another fellow's clutches, I'm your man," agreed Jakdane heartily. "I always had a mind to save you for myself. I'll guarantee you won't have a moment alone with him the whole trip."

"You don't have to be that thorough about it," she protested hastily. "I want to get a little enjoyment out of being in love. But if I feel myself weakening too much, I'll holler for help."

The Cometfire swung around great Jupiter in an opening arc and plummeted ever more swiftly toward the tight circles of the inner planets. There were four crew members and three passengers aboard the ship's tiny personnel sphere, and Trella was thrown with Quest almost constantly. She enjoyed every minute of it.

She told him only that she was a messenger, sent out to Ganymede to pick up some important papers and take them back to Earth. She was tempted to tell him what the papers were. Her employer had impressed upon her that her mission was confidential, but surely Dom Blessing could not object to Dr. Mansard's son knowing about it.

All these things had happened before she was born, and she did not know what Dom Blessing's relation to Dr. Mansard had been, but it must have been very close. She knew that Dr. Mansard had invented the surgiscope.

This was an instrument with a three-dimensional screen as its heart. The screen was a cubical frame in which an apparently solid image was built up of an object under an electron microscope.

* * * * *

The actual cutting instrument of the surgiscope was an ion stream. By operating a tool in the three-dimensional screen, corresponding movements were made by the ion stream on the object under the microscope. The principle was the same as that used in operation of remote control "hands" in atomic laboratories to handle hot material, and with the surgiscope very delicate operations could be performed at the cellular level.

Dr. Mansard and his wife had disappeared into the turbulent atmosphere of Jupiter just after his invention of the surgiscope, and it had been developed by Dom Blessing. Its success had built Spaceway Instruments, Incorporated, which Blessing headed.

Through all these years since Dr. Mansard's disappearance, Blessing had been searching the Jovian moons for a second, hidden laboratory of Dr. Mansard. When it was found at last, he sent Trella, his most trusted secretary, to Ganymede to bring back to him the notebooks found there.

Blessing would, of course, be happy to learn that a son of Dr. Mansard lived, and would see that he received his rightful share of the inheritance. Because of this, Trella was tempted to tell Quest the good news herself; but she decided against it. It was Blessing's privilege to do this his own way, and he might not appreciate her meddling.

* * * * *

At midtrip, Trella made a rueful confession to Jakdane.

"It seems I was taking unnecessary precautions when I asked you to be a chaperon," she said. "I kept waiting for Quest to do something, and when he didn't I told him I loved him."

"What did he say?"

"It's very peculiar," she said unhappily. "He said he can't love me. He said he wants to love me and he feels that he should, but there's something in him that refuses to permit it."

She expected Jakdane to salve her wounded feelings with a sympathetic pleasantry, but he did not. Instead, he just looked at her very thoughtfully and said no more about the matter.

He explained his attitude after Asrange ran amuck.

Asrange was the third passenger. He was a lean, saturnine individual who said little and kept to himself as much as possible. He was distantly polite in his relations with both crew and other passengers, and never showed the slightest spark of emotion ... until the day Quest squirted coffee on him.

It was one of those accidents that can occur easily in space. The passengers and the two crewmen on that particular waking shift (including Jakdane) were eating lunch on the center-deck. Quest picked up his bulb of coffee, but inadvertently pressed it before he got it to his lips. The coffee squirted all over the front of Asrange's clean white tunic.

"I'm sorry!" exclaimed Quest in distress.

The man's eyes went wide and he snarled. So quickly it seemed impossible, he had unbuckled himself from his seat and hurled himself backward from the table with an incoherent cry. He seized the first object his hand touched--it happened to be a heavy wooden cane leaning against Jakdane's bunk--propelled himself like a projectile at Quest.

Quest rose from the table in a sudden uncoiling of movement. He did not unbuckle his safety belt--he rose and it snapped like a string.

For a moment Trella thought he was going to meet Asrange's assault. But he fled in a long leap toward the companionway leading to the astrogation deck above. Landing feet-first in the middle of the table and rebounding, Asrange pursued with the stick upraised.

In his haste, Quest missed the companionway in his leap and was cornered against one of the bunks. Asrange descended on him like an avenging angel and, holding onto the bunk with one hand, rained savage blows on his head and shoulders with the heavy stick.

Quest made no effort to retaliate. He cowered under the attack, holding his hands in front of him as if to ward it off. In a moment, Jakdane and the other crewman had reached Asrange and pulled him off.

* * * * *

When they had Asrange in irons, Jakdane turned to Quest, who was now sitting unhappily at the table.

"Take it easy," he advised. "I'll wake the psychosurgeon and have him look you over. Just stay there."

Quest shook his head.

"Don't bother him," he said. "It's nothing but a few bruises."

"Bruises? Man, that club could have broken your skull! Or a couple of ribs, at the very least."

"I'm all right," insisted Quest; and when the skeptical Jakdane insisted on examining him carefully, he had to admit it. There was hardly a mark on him from the blows.

"If it didn't hurt you any more than that, why didn't you take that stick away from him?" demanded Jakdane. "You could have, easily."

"I couldn't," said Quest miserably, and turned his face away.

Later, alone with Trella on the control deck, Jakdane gave her some sober advice.

"If you think you're in love with Quest, forget it," he said.

"Why? Because he's a coward? I know that ought to make me despise him, but it doesn't any more."

"Not because he's a coward. Because he's an android!"

"What? Jakdane, you can't be serious!"

"I am. I say he's an android, an artificial imitation of a man. It all figures.

"Look, Trella, he said he was born on Jupiter. A human could stand the gravity of Jupiter, inside a dome or a ship, but what human could stand the rocket acceleration necessary to break free of Jupiter? Here's a man strong enough to break a spaceship safety belt just by getting up out of his chair against it, tough enough to take a beating with a heavy stick without being injured. How can you believe he's really human?"

Trella remembered the thug Kregg striking Quest in the face and then crying that he had injured his hand on the bar.

"But he said Dr. Mansard was his father," protested Trella.

"Robots and androids frequently look on their makers as their parents," said Jakdane. "Quest may not even know he's artificial. Do you know how Mansard died?"

"The oxygen equipment failed, Quest said."

"Yes. Do you know when?"

"No. Quest never did tell me, that I remember."

"He told me: a year before Quest made his rocket flight to Ganymede! If the oxygen equipment failed, how do you think Quest lived in the poisonous atmosphere of Jupiter, if he's human?"

Trella was silent.

"For the protection of humans, there are two psychological traits built into every robot and android," said Jakdane gently. "The first is that they can never, under any circumstances, attack a human being, even in self defense. The second is that, while they may understand sexual desire objectively, they can never experience it themselves.

"Those characteristics fit your man Quest to a T, Trella. There is no other explanation for him: he must be an android."

* * * * *

Trella did not want to believe Jakdane was right, but his reasoning was unassailable. Looking upon Quest as an android, many things were explained: his great strength, his short, broad build, his immunity to injury, his refusal to defend himself against a human, his inability to return Trella's love for him.

It was not inconceivable that she should have unknowingly fallen in love with an android. Humans could love androids, with real affection, even knowing that they were artificial. There were instances of android nursemaids who were virtually members of the families owning them.

She was glad now that she had not told Quest of her mission to Ganymede. He thought he was Dr. Mansard's son, but an android had no legal right of inheritance from his owner. She would leave it to Dom Blessing to decide what to do about Quest.

Thus she did not, as she had intended originally, speak to Quest about seeing him again after she had completed her assignment. Even if Jakdane was wrong and Quest was human--as now seemed unlikely--Quest had told her he could not love her. Her best course was to try to forget him.

Nor did Quest try to arrange with her for a later meeting.

"It has been pleasant knowing you, Trella," he said when they left the G-boat at White Sands. A faraway look came into his blue eyes, and he added: "I'm sorry things couldn't have been different, somehow."

"Let's don't be sorry for what we can't help," she said gently, taking his hand in farewell.

Trella took a fast plane from White Sands, and twenty-four hours later walked up the front steps of the familiar brownstone house on the outskirts of Washington.

Dom Blessing himself met her at the door, a stooped, graying man who peered at her over his spectacles.

"You have the papers, eh?" he said, spying the brief case. "Good, good. Come in and we'll see what we have, eh?"

She accompanied him through the bare, windowless anteroom which had always seemed to her such a strange feature of this luxurious house, and they entered the big living room. They sat before a fire in the old-fashioned fireplace and Blessing opened the brief case with trembling hands.

"There are things here," he said, his eyes sparkling as he glanced through the notebooks. "Yes, there are things here. We shall make something of these, Miss Trella, eh?"

"I'm glad they're something you can use, Mr. Blessing," she said. "There's something else I found on my trip, that I think I should tell you about."

She told him about Quest.

"He thinks he's the son of Dr. Mansard," she finished, "but apparently he is, without knowing it, an android Dr. Mansard built on Jupiter."

"He came back to Earth with you, eh?" asked Blessing intently.

"Yes. I'm afraid it's your decision whether to let him go on living as a man or to tell him he's an android and claim ownership as Dr. Mansard's heir."

Trella planned to spend a few days resting in her employer's spacious home, and then to take a short vacation before resuming her duties as his confidential secretary. The next morning when she came down from her room, a change had been made.

Two armed men were with Dom Blessing at breakfast and accompanied him wherever he went. She discovered that two more men with guns were stationed in the bare anteroom and a guard was stationed at every entrance to the house.

"Why all the protection?" she asked Blessing.

"A wealthy man must be careful," said Blessing cheerfully. "When we don't understand all the implications of new circumstances, we must be prepared for anything, eh?"

There was only one new circumstance Trella could think of. Without actually intending to, she exclaimed:

"You aren't afraid of Quest? Why, an android can't hurt a human!"

Blessing peered at her over his spectacles.

"And what if he isn't an android, eh? And if he is--what if old Mansard didn't build in the prohibition against harming humans that's required by law? What about that, eh?"

Trella was silent, shocked. There was something here she hadn't known about, hadn't even suspected. For some reason, Dom Blessing feared Dr. Eriklund Mansard ... or his heir ... or his mechanical servant.

* * * * *

She was sure that Blessing was wrong, that Quest, whether man or android, intended no harm to him. Surely, Quest would have said something of such bitterness during their long time together on Ganymede and aspace, since he did not know of Trella's connection with Blessing. But, since this was to be the atmosphere of Blessing's house, she was glad that he decided to assign her to take the Mansard papers to the New York laboratory.

Quest came the day before she was scheduled to leave.

Trella was in the living room with Blessing, discussing the instructions she was to give to the laboratory officials in New York. The two bodyguards were with them. The other guards were at their posts.

Trella heard the doorbell ring. The heavy oaken front door was kept locked now, and the guards in the anteroom examined callers through a tiny window.

Suddenly alarm bells rang all over the house. There was a terrific crash outside the room as the front door splintered. There were shouts and the sound of a shot.

"The steel doors!" cried Blessing, turning white. "Let's get out of here."

He and his bodyguards ran through the back of the house out of the garage.

Blessing, ahead of the rest, leaped into one of the cars and started the engine.

The door from the house shattered and Quest burst through. The two guards turned and fired together.

He could be hurt by bullets. He was staggered momentarily.

Then, in a blur of motion, he sprang forward and swept the guards aside with one hand with such force that they skidded across the floor and lay in an unconscious heap against the rear of the garage. Trella had opened the door of the car, but it was wrenched from her hand as Blessing stepped on the accelerator and it leaped into the driveway with spinning wheels.

Quest was after it, like a chunky deer, running faster than Trella had ever seen a man run before.

Blessing slowed for the turn at the end of the driveway and glanced back over his shoulder. Seeing Quest almost upon him, he slammed down the accelerator and twisted the wheel hard.

The car whipped into the street, careened, and rolled over and over, bringing up against a tree on the other side in a twisted tangle of wreckage.

With a horrified gasp, Trella ran down the driveway toward the smoking heap of metal. Quest was already beside it, probing it. As she reached his side, he lifted the torn body of Dom Blessing. Blessing was dead.

"I'm lucky," said Quest soberly. "I would have murdered him."

"But why, Quest? I knew he was afraid of you, but he didn't tell me why."

"It was conditioned into me," answered Quest "I didn't know it until just now, when it ended, but my father conditioned me psychologically from my birth to the task of hunting down Dom Blessing and killing him. It was an unconscious drive in me that wouldn't release me until the task was finished.

"You see, Blessing was my father's assistant on Ganymede. Right after my father completed development of the surgiscope, he and my mother blasted off for Io. Blessing wanted the valuable rights to the surgiscope, and he sabotaged the ship's drive so it would fall into Jupiter.

"But my father was able to control it in the heavy atmosphere of Jupiter, and landed it successfully. I was born there, and he conditioned me to come to Earth and track down Blessing. I know now that it was part of the conditioning that I was unable to fight any other man until my task was finished: it might have gotten me in trouble and diverted me from that purpose."

More gently than Trella would have believed possible for his Jupiter-strong muscles, Quest took her in his arms.

"Now I can say I love you," he said. "That was part of the conditioning too: I couldn't love any woman until my job was done."

Trella disengaged herself.

"I'm sorry," she said. "Don't you know this, too, now: that you're not a man, but an android?"

He looked at her in astonishment, stunned by her words.

"What in space makes you think that?" he demanded.

"Why, Quest, it's obvious," she cried, tears in her eyes. "Everything about you ... your build, suited for Jupiter's gravity ... your strength ... the fact that you were able to live in Jupiter's atmosphere after the oxygen equipment failed. I know you think Dr. Mansard was your father, but androids often believe that."

He grinned at her.

"I'm no android," he said confidently. "Do you forget my father was inventor of the surgiscope? He knew I'd have to grow up on Jupiter, and he operated on the genes before I was born. He altered my inherited characteristics to adapt me to the climate of Jupiter ... even to being able to breathe a chlorine atmosphere as well as an oxygen atmosphere."

Trella looked at him. He was not badly hurt, any more than an elephant would have been, but his tunic was stained with red blood where the bullets had struck him. Normal android blood was green.

"How can you be sure?" she asked doubtfully.

"Androids are made," he answered with a laugh. "They don't grow up. And I remember my boyhood on Jupiter very well."

He took her in his arms again, and this time she did not resist. His lips were very human.

THE END

THIS WORLD MUST DIE!

By H. B. Fyfe

 

Lou Phillips sat on the cold metal deck of the control room, seething with a growing dislike for the old man.

"What you are here for," the other had told him when the guards had brought Phillips in, "is a simple crime of violence. You'll do, I'm sure."

The old man paced the deck impatiently, while a pair of armed guards maintained a watchful silence by the door. Two more men in plain gray shirts and trousers sat beside Phillips, leaning back sullenly against the bulkhead. He guessed that they were waiting for a fourth, remembering that three other figures had been hustled aboard with him at the Lunar spaceport.

The door slid open, allowing another youth in gray uniform to stumble inside. One of the guards in the corridor beyond shoved the newcomer forward, and Phillips' eyebrows twitched as he had a closer look. This last prisoner was a girl.

He thought she might have been pretty, with a touch of lipstick and a kinder arrangement of her short, ash-blonde hair; but he lowered his eyes as her hard, wary stare flickered past him. She walked over to the bulkhead and took a seat at the other end of the little group.

The old man turned, scanning their faces critically. "I am in charge of a peculiar project," he announced abruptly. "The director of the Lunar Detention Colony claims that you four are the best he has--for our purposes!"

Long habit kept the seated ones guardedly silent. Seeing, apparently, that they would not relax, he continued.

"You were chosen because each of you has received a sentence of detention for life because of tendencies toward violence in one form or another. In our twenty-second century civilization such homicidal inclinations are quite rare, due to the law-abiding habits of generations under the Interplanetary Council."

He had been pacing the cramped space left free by the equipment, the guards, and the four seated prisoners. Now he paused, as if mildly astonished at what he was about to say.

"In fact, now that we are faced by a situation demanding illegal violence, it appears that no normal citizen is capable of committing such an act. Using you may eliminate costly screening processes ... and save time. Incidentally, I am Anthony Varret, Undersecretary for Security in the Council."

None of the four showed any overt sign of being impressed. Phillips knew that the others, like himself, were scrutinizing the old man with cold, secretive stares. They had learned through harsh experience to keep their own counsels. Varret shrugged. "Well, then," he said dryly, "I might as well call the roll. I have been supplied with accurate records."

* * * * *

He drew a notebook from his pocket, consulted it briefly, then nodded at the man next to the girl. "Robert Brecken," he recited, "age thirty-one, six feet, one hundred eighty-five pounds, hair reddish brown, eyes green, complexion ruddy. Convicted of unjustified homicide by personal assault while resisting arrest for embezzlement. Detention record unsatisfactory. Implicated in two minor mutinies."

He glanced next at the youth beside Phillips. "Raymond Truesdale, age twenty-two, five-feet-five, one-thirty. Hair black, eyes dark brown, complexion pale. Convicted of two suicide attempts following failures in various artistic fields. Detention record fair, psychological report poor."

His frosty eyes met Phillips'. "Louis Phillips, age twenty-six, five-ten, one-eighty. Hair brown, eyes brown, complexion darkly tanned--that was before Luna, wasn't it, Phillips? Convicted of unjustified homicide, having assaulted a jet mechanic so as to cause death. Detention record satisfactory."

The blonde girl was last in Varret's review. "Donna Bailey, age twenty-three, five-five, one-fifteen. Hair blonde, eyes blue, complexion fair. Convicted of manslaughter by negligence, while piloting an atmosphere sport rocket in an intoxicated condition. Detention record satisfactory."

Varret fell silent, regarding them with cynical disgust. His lips twisted slightly with distaste. "There we have it," he said. "A violent-tempered thief from the business world; an over-expensive purchase by a rich playboy who became his widow by her own negligence; a mentally-unstable fool who thought he was artistically gifted, and a rocket engineer who was too brutally careless with his own strength when irritated by a space-fatigued helper. I wonder if you'll do...?"

Phillips felt impelled at last to speak. "Just what plans do you have for us?" he demanded harshly.

"Nothing complicated," replied Varret, matching the tone. "We need you to perform a mass murder!"

Phillips blinked, despite his prison-learned reserve. He heard the girl suck in her breath sharply, and felt the youth beside him begin to tremble.

"I have shocked you, I see," sneered Varret. "Well, I assure you, it shocks me also, probably a good deal more since I have lived a normal life. However--this is the background:

"About three months ago, we had reports of the outbreak of a deadly plague in one of the asteroid groups. As near as can be determined, it was spread by the crew of an exploratory rocket after the discovery of a new asteroid. It began to sweep through the mining colonies out there with the velocity of an expanding nova!"

"Where was your Health Department?" asked the man named Brecken in a sneering tone.

Varret frowned at him. "Several members gave their lives trying to learn the nature of the disease. We have no information to date, except a theory that it attacks the nervous and circulatory systems, because the reports indicate that the reason of the victim is markedly affected as the disease progresses. Not a single survivor is known--they all die in raving insanity. We do not even know with certainty how it is communicated."

"What are you doing?" asked Phillips.

"Isolation. It is all we can do, until our medical men can make some progress. We evacuated an asteroid colony and began to ship into it any person showing any of the symptoms, using a cruiser piloted by remote control. That was where we slipped."

"How?"

"On the last trip--unless we have not really collected all the sufferers--we lost control. Someone being transported knew his spaceships. Shortly thereafter, a gibbering lunatic got on the screen and threatened the escorting rocket. He announced the cruiser would head for Mars, where the passengers would demand their freedom. They are past reasoning with."

"Can't say I really blame them," Phillips remarked.

"Blame them? Of course not! Neither do I. What has that to do with it? What has the Council so worried is that this thing will get loose on Mars, that it may even be carried to Earth and Venus. There are over a hundred persons in that ship, no longer responsible for their actions but capable of causing deaths by the billions. We want to help them, but we simply must hold the line on this quarantine until we solve the medical problem."

* * * * *

They stared at him in silence, and Phillips noticed that the old man's forehead was moist with tiny beads of perspiration.

"Don't you see? They are as good as dead. No knowledge or help of man can save them--as of this moment. If we are ever to be of any help, we must prevent a worse catastrophe.

"Yes, the survival ship is a world in itself, but this world must die!"

For a minute or two, it seemed to Phillips that he could hear each person in the control room breathing. Finally, there was a small sound of cloth rubbing on metal as Brecken stirred. "Why pick on us?" he rasped from his seat on the deck. "I'm no volunteer!"

"I know what you are," replied Varret sharply. "I know what you all are. You have been chosen for this mission of murder, because you are the only people in our culture who are capable of this kind of violence. You have broken our laws, and this is your punishment.

"It would take us too long to find others like you who had merely never faced the same circumstances that sent you four to Luna. We have made attempts to attack this vessel. Manned by normal men, our ships could accomplish nothing."

"Why not?" asked Phillips.

"The crews found they could not kill!"

"What?"

"It amounts to that. One pilot blacked out at the start of an offensive approach. He lost contact before recovering--you realize how quickly that happens at interplanetary speeds. On several other ships, there were passive mutinies. One was destroyed; how, we do not know."

"Why don't you get some men in your Department of Security?" sneered Brecken.

Varret sighed. "It was far from simple cowardice. The crews had fine records. We have been civilized too long, so long that the idea of deliberate killing unnerved them. As to the one ship that did make some motion to attack, it may have been destroyed by the cruiser's defenses, or even by sabotage. Somebody may quite possibly have found the mission too repulsive to face with complete sanity."

He was interrupted by a uniformed man, who slid the door open and gestured significantly. Varret paused. He nodded, and the newcomer retired.

"I have only a few minutes," said the old man, facing them again. "To be brief, this patrol vessel is armed with the best we have in guided atomic missiles and sensitive detection devices. Technical manuals are supplied for everything we could think of, though I doubt you will need them. We have brought you to within a few hundred miles of them.

"In a few minutes, my men and I will transfer to an escort ship. We will slip in behind Deimos, not too far away, and pick you up afterward to land you on Mars. Any questions?"

"Yes," said Phillips.

"What?"

"Why should we do anything at all?"

Varret's lips tightened. A guard shrugged contemptuously. "I was told to expect that attitude," the old man admitted. "I suppose it is part of the character we now think is needed for such an expedition."

"You could hardly expect co-operation," Phillips pointed out. "Laws against any kind of homicide are all well enough, but I for one don't see why I should draw the same sentence as a murderer. I had to protect myself or die--probably through having that crazy fool blow up my rocket room."

"You'll make a cold landing on Sol before you'll get any help from me!" Brecken added defiantly.

The girl said nothing, but Truesdale muttered darkly.

"Please!" said Varret. "I have no time to argue about our social and legal codes. The Council foresaw that the threat of being yourselves subject to this plague might not be enough. If you succeed in destroying or even immobilizing the cruiser, I can offer you anything you want short of unsupervised liberty. You must still be watched as potential dangers to society, but you may otherwise be as wealthy or independent as you wish."

He motioned to the guards, who had begun to fidget impatiently; wordlessly they left the compartment.

"You can settle your relations among yourselves," said Varret. "We chose Bailey partly because she has piloted rockets privately, and Phillips because he was a space engineer. Perhaps Brecken could handle the torpedoes--I do not know." He rubbed his chin uneasily. "Frankly, I find intimate discussion of the affair repulsive. I hope you will decide to do what is necessary for the welfare of Earth."

He turned abruptly and left the control room. They heard distant voices exhorting him to hurry.

Brecken arose and crept furtively to the door. He leaned out to peer down the corridor. The nervous Truesdale bounced up to crowd behind him. Phillips and the girl looked at each other; she shrugged, and they too got to their feet. She turned to the instrument panels; and after a moment, Phillips joined her.

"How have they got it?" he asked. "Controls locked?"

"No," murmured Donna. "Don't need to; we're just coasting. Nice job, though. Fast as a racer, I imagine."

"You know something about racers?"

"I used to think I did," she answered, shortly.

He saw pain darken her blue eyes and decided to probe no further. Instead, he wandered about, inspecting the instruments. A few minutes later, with a spaceman's indefinable alertness, he felt a change in the ship.

"They still aboard?" he called to Truesdale, who remained at the door although Brecken had disappeared.

The youth glanced over his shoulder but did not trouble to reply. Phillips' jaw set, and he took a quick step toward the other. Before he reached the doorway, however, Brecken returned from the corridor. Shouldering Truesdale aside, he strode into the control room. "Well," he announced, "the old fool hopped off like he said. Got a viewer in here?"

"I have it on now," called Donna from the instrument desk. "There he goes."

They gathered around the screen to watch. Near one edge was the image of another ship, with several spacesuited figures clustered around its entrance port. The girl made an adjustment, and the view crept over to the center of the screen just as the last of the figures vanished into the opening. Almost immediately, the other rocket slanted away on a new course.

Donna followed it on the screen until the brief flashes of its jets were dimmed by a new radiance--the ruddy disk of Mars. "We are where he said," she admitted. "Now what?"

She looked at Phillips, who merely shrugged. "What do you make of it?" she insisted.

"Pretty much as he said, probably," answered the engineer. "He's heading for Deimos, I suppose. I hear they're landscaping the whole moon--it's only about five miles in diameter--and building a new space station for a radio beacon and relay."

"Does that log say anything about the plague ship?" asked Truesdale nervously.

Donna scanned the observation record, then adjusted the viewer. The red radiance of Mars fled, to be replaced by a dimmer scene of distant stars.

"In there someplace," she said. "Out of range of this screen, but we could probably locate it with detector instruments."

"Why all the jabber?" demanded Brecken. "Let's get going!"

Phillips stared at him. "What's the rush? Did he sell you that easily?"

"Huh? Oh, hell, no! I mean let's make a dive for Mars. They were dumb to set us loose with a fast ship. We're dumber if we don't use it!"

"That's right," agreed Truesdale eagerly. "We don't owe them anything. They owe us; for the years they took out of our lives!"

* * * * *

Truesdale had a point there, Phillips felt. This could grow into quite a discussion, and he was not sure which side he wanted to take. He had no great urge to become a hero, but on the other hand there was something about Brecken that aroused a certain obstinacy in him.

"Wait a minute!" Donna protested; "what do you think you're going to do?"

"Slip into a curve for Mars," said Brecken. "Slow down enough to take to chutes an' let this can smack up in the deserts somewhere. They'll never know if we got out, an' we'll be on our own."

The girl turned to Phillips. "How about you?" she asked. "Don't you think we should at least consider what Varret told us? If this plague is as dangerous as he says, this is no time to--"

"Do you have to be so bloodthirsty?" complained Truesdale.

"I don't want to kill anybody," declared the girl; "maybe we could just disable the cruiser."

"Aw, kill your jets!" Brecken broke in. "I've been waiting for a chance like this for years. Don't get any ideas!"

"But listen!" pleaded Donna. "It's a terrible thing, but if we don't do it, we won't be safe on Mars ourselves; they'll land and set an epidemic loose."

"I'll take my chances with it," said Brecken. "You're supposed to know something about piloting. Now get us on a curve for Mars, an' be snappy about it!"

Donna turned desperately to Phillips.

"Why not look over the ship," the engineer suggested, "before we blast off on half our jets? We can make up our minds when we see what we have for fuel and weapons."

Brecken opened his mouth to object, but was smitten by an unpleasant thought. "Suppose they didn't leave us enough fuel to make Mars!"

"We can find out soon enough," said Phillips, leading the way to the door.

They trooped down the corridor on his heels, past the few closet-like compartments set aside for living quarters. It was a single-deck ship, with storage compartments above and below for fuel, oxygen, and other necessities. The corridor was liberally supplied with handrails, apparently in case of failure of the artificial gravity system.

About halfway to the end, another passage crossed the fore-and-aft one, and a few steps farther was a ladder. This extended up and down a vertical well, which in space amounted to a second cross corridor. Phillips was right when he guessed that the door beyond opened into the rocket room.

The others were bored by the power plant of the ship. The engineer, however, could not repress a thrill at once more standing surrounded by the gauges, valves, and pumps with which he had formerly lived. He strode about, examining and comprehending such appliances as seemed new since his last service in space.

"How about it?" demanded Brecken. "Can you handle it?"

"Sure," answered Phillips confidently. "Mostly automatic anyway."

"Then we can get movin' whenever we want?"

"I suppose so. The tanks are nearly full; let's find those space torpedoes the old man mentioned."

"Maybe it won't hurt, at that," grumbled Brecken.

* * * * *

He led the way out, but paused indecisively. Phillips stepped past him and considered the cross passages near the midpoint of the corridor. Those in the plane of the control room deck probably led to port and starboard airlocks, he reasoned, so the others might lead to the torpedo turrets.

He went to the vertical well and started up the ladder, hearing the others follow. At the top, he was confronted by a hatch with a red danger sign. Glancing about, he located the gauges that reported the air pressure beyond. Normal.

"Make a little room," he said, looking down to Brecken.

The big, ruddy face retreated a few rungs. Phillips could hear the others scrambling further down. He got his head out of the way before pulling the switch that opened the hatch. With a subdued humming of electric motors, the massively constructed door swung down. One after another, they pulled themselves up into the compartment.

"This must be where they set controls for launching," guessed Phillips, leaning back against a rack of emergency spacesuits. "That intercom screen on the bulkhead is probably plugged in to the control room. Looks as if the torpedoes themselves are stored under that hatch at the after end."

"How do they kick them off?" asked Brecken.

"Those conveyor belts run them into tubes in the forward bulkhead. A charge of compressed air blows them out, and then the rockets are started and controlled by radio."

"You mean we have to point at a target to fire?"

"Oh, no. Once the rockets are going, the torpedo can be maneuvered and aimed anywhere by remote control."

"I've seen enough," announced Truesdale. "I'm hungry."

At that, they all decided to return to the main deck. Phillips carefully closed the airtight hatch as they left, then followed the others in search of the galley.

Later, after a very unsatisfactory meal of packaged concentrates, they loitered sullenly in the control room once more while Donna studied the controls. Phillips had finally decided that he could wear the third spacesuit on the rack if he had to. He was idly examining the tools supplied with it when his thoughts were interrupted.

Young Truesdale had been monkeying with a range indicator for some time, but now his sharp outcry drew all eyes to him.

The others immediately gathered to peer over his shoulder. A needle flickered wildly from one side of the dial to the other.

"Here! Get it balanced," said Phillips, thrusting a powerful arm between the crowded bodies. As his deft adjustment steadied the needle, he stepped back and leaned against the bulkhead to study their faces. Truesdale's was pale.

"It's them!" he panted.

"Well," asked Donna, "what will it be?"

"Whaddya mean?" demanded Brecken, red-faced. "It'll be get dam' well outa here, that's what it'll be!"

"Let's see you go," invited the girl coolly. "How well do you pilot a rocket?"

Brecken's jaw dropped. "Wh-wh-what? You crazy? Did you swallow all that stuff the old man told you?" he sputtered.

"Why not?" asked Donna. "They didn't bring us all the way out here for nothing. Varret was scared. If it's that dangerous, somebody just has to do it--and we're here!"

"Not for long," said Brecken in an ugly tone. "Get hot on those controls. You, Phillips! Run back to that rocket room and see that things work!"

"You try it," suggested the engineer quietly.

He would have preferred to avoid the trouble the girl had been stirring up, but he did not relish Brecken's tone. A few days off Luna, he reflected, and already he was getting independent.

"Listen," said Donna, encouraged in her defiance, "when I touch those controls, we'll go right up and touch noses with them. You'd better have a torpedo ready!"

She turned to the banks of buttons and switches. Muffled thunder from the stern jets trembled through the hull as the men staggered.

Brecken recovered his balance first. With a snarl, he grabbed the girl by the nape of the neck and shook her roughly. Glimpsing Phillips' cold sneer, he reached back and seized a heavy metal bar from the spacesuit rack.

"Now, dammit!" he grated. "You'll do like I tell you! And you get back there an' see that those tubes recharge okay!"

Phillips felt a hard anger swelling his throat. From the corner of his eye, he saw Truesdale shrinking back against the bulkhead. He glanced about desperately for something with which to parry Brecken's bar.

It was the girl who broke the tense silence. With a gasping intake of breath, she reached up to claw at Brecken's face. Cursing, the man twisted his head away to protect his eyes. He released his grip on the girl's neck and swung a clumsy, backhand blow at her head. Donna stumbled, and collapsed to the deck.

Now or never, Phillips told himself. Without waiting to think, he hurled himself forward.

Brecken saw him coming, and tried to shift around to meet the engineer's charge. Phillips crashed into him shoulder first, and they both brought up against the opposite bulkhead with a thud. He concentrated all his strength into wringing the other's forearm until he heard the bar clang to the deck.

Brecken clubbed him on the side of the head with a wild left swing, and Phillips found the big man's foot in the way when he tried to sidestep. He lost his balance, but kept his grasp on the other so that they went down together, thrashing about for some opening. Brecken was red-faced with a maniacal rage. Beads of saliva sprayed from his twisted lips as he sputtered curses.

The engineer let go suddenly and jolted the other under the chin with the heel of his left hand. The man arched backward, but Phillips caught a knee in the chest that sent him slithering across the deck. As he strove to twist to his hands and knees, he saw Brecken groping for the bar.

Never reach him, thought Phillips frantically.

Thrusting one foot against the leg of an anchored data desk, he raised himself half upright as he lunged desperately at Brecken. Strangely, it occurred to Phillips for a fleeting lapse of time that old Varret had been reasonably astute in his selections, if he desired violent-tempered throwbacks. Then the breath was knocked out of him as he smashed into Brecken with a force that sent them both hurtling into the bulkhead.

The other's grunt of pain was almost lost beneath the sharp smack of bone against metal. Phillips scrambled up hastily, but his opponent lay still.

Over by the data desk, Donna was beginning to squirm quietly and make groping motions with her outstretched hands. Truesdale had retreated to the forward end of the control room, his features blanched by apprehension.

I'll bet, thought Phillips, that old Varret slipped up in your case, my lad. Your reaction to violence must be what they call normal.

He beckoned brusquely. "Give me a hand with him," he ordered.

Brecken still showed no sign of consciousness. Truesdale approached warily, and with his aid Phillips lifted the unconscious man. With their burden limp in their hands, they staggered down the corridor to one of the sleeping compartments. There, they slung him into a bunk.

"He needs attention," said Truesdale.

"He won't get it from me," snapped Phillips. "Lumps on the head were his idea; there's no time to fool with him."

He pulled the sliding door shut, noticing that it had no lock. Since Brecken would probably be some time recovering, however, he put that out of his mind.

* * * * *

Having returned to the control room, they discovered Donna sitting up. At the sight of them, she pulled herself somewhat shakily to a standing position, and brushed back her blonde hair.

"What happened?" she asked.

"He bumped his head on the bulkhead," said Phillips shortly.

This was accepted without comment. They turned to the instruments and examined the dial of the range indicator.

"They aren't very far away," said Donna quietly. "Where do you stand now, Phillips?"

"I suppose we'd better do it," he admitted. "Pretty vicious, aren't you?"

"No!" she snapped. "I don't like it either; I've never caused the death of any human being."

"Oh, sure. That's why you were on Luna!"

She looked at him levelly in the eye, but her shoulders drooped a trifle with the resignation of one who has often been disbelieved.

"My husband was a nice guy," she murmured, "but he never did know when he had a drink too many for piloting his jet. He passed out trying to give me a wild ride, and I got to the controls just in time to crash-land the rocket; that's where they found me before I came to."

"Oh," said Phillips.

"I'm not half as hard as I'm trying to pretend," Donna went on, "even after a year on Luna. But I was a nurse before I was married. I'm thinking about what it will be like if this plague hits the planets before they find something to fight it with. The children ... imagine that, will you?"

Phillips stared at the range indicator. It seemed there were times when an ugly thing had to be done for the common good. He wondered how the old-time executioners had felt, in the days when there had been judicial homicide. There were still jailers, for that matter, and men who butchered cattle.

"Call it a mercy killing," murmured Donna between pale lips. "Maybe you think that isn't still done once in a while, in spite of modern society."

"Ummh," Phillips grunted. "Well, if you can watch at this end, Truesdale and I can go set up a couple of torpedoes. I hope those rocket blasts didn't give us away."

"According to Varret," said Truesdale, "there can't be many of them still able to think straight enough to stand on watch. I wonder what it's like...."

Phillips glanced askance at him, but led the way into the corridor. First of all, he stopped at the rocket room to check the tube readings. The fired jets had been automatically recharged.

* * * * *

They left the rocket room and climbed the ladder to the turret. Once inside, Phillips spent the first few minutes inspecting the equipment and thumbing through the manuals left there by Varret. Finally, the bored Truesdale broke in upon his study.

"That old goat must be crazy to think he could toss us out here and have us act like a trained crew. How can we even hope to do anything right, without blowing ourselves up?"

"We can try," said Phillips coldly. "It shouldn't be impossible to get one started, at least."

He found the twin control panels in the bulkhead, and pulled a pair of switches. There was a smooth humming and a slight click as two hatches in the deck slid open. Slanting metal chutes rose out of the dark apertures, just behind the conveyor belts.

"Look at those babies!" breathed Phillips.

The snouts of two miniature spaceships protruded from the storage hold. Phillips touched other switches, and the sleek missiles were prodded onto the belts and moved forward until the full, twenty-foot lengths were in view.

"Phillips, you better be careful with those things!" quavered Truesdale as the engineer unscrewed a small hatch on one.

"Afraid I'll blow it up?" asked Phillips, peering inside.

"Why not? You never touched one before."

"You go ahead and believe that," retorted the engineer. "Now, I'll just turn on the radio controls, check the batteries, and feed the bad news into the launching tubes. Watch!"

Replacing the hatch and securing it, he thought out the procedure to use at the remote control panels. Turning on the screen above one of them produced a cross-haired image of the bulkhead directly in front of the near torpedo. He tried various manipulations until he had focused the view and caused it to sweep all around the interior of the turret. After idly watching himself and Truesdale appear on the screen, he returned the view to dead ahead, switched it off, and turned to the other panel.

"I guess I can finish checking," he said.

Truesdale clambered hastily down the ladder. Phillips shook his head. "Don't know what use he'll be," he muttered. "Too bad Brecken wouldn't listen. He at least ... oh, well!"

He wondered whether he himself would stand up when the time came. What Varret had asked did not sound like much. Just a quick shot and watch them blow apart. What inhibitions made men black out rather than carry it through? It was not as if there were any hope for these people. Surely, it was obvious that to permit them, in their deranged state, to spread a catastrophic plague was inconceivable. But perhaps emotions were stronger than reason.

"I'll find out pretty soon," he reflected.

There was little more to do in the turret, except to run the torpedoes into the launching tubes and bring up a new pair in reserve. With that much done, he closed the hatch and climbed down the ladder.

* * * * *

In the control room, he found Donna and Truesdale peering into the screen. He crowded close to look over their shoulders. A small blob of light floated near the center of the view. "That it?" he asked.

"Yes," answered Donna. "Just enough Mars-light to show it."

"How near are we?" asked Phillips.

"About a hundred and fifty miles. I have quite a large magnification, but they may spot us if they're alert. Are you ready to ... do something?"

"Reasonably," said Phillips. "Where's Brecken?"

"You probably killed him!" Truesdale broke in accusingly.

"I found a first-aid kit and gave him a shot," said Donna. "He has a nasty lump on the head, but he might sleep it off."

Phillips was watching Truesdale. The youth was visibly nervous. Was it the thought of Brecken, the engineer wondered, or fear of what they were planning to do? Perhaps it would be best to clear the air now, before it was too late.

"I guess you can handle it here, Donna," he said. "Truesdale and I will go to the turret and stand by."

The youth shrank away. "No! I won't go up there again! You can't make me do this!"

"Do what?" demanded Phillips.

"It's murder! You both know it is! They won't even have any warning."

"I hope not," said Phillips drily. "They might get us!"

"You would put it that way," sneered Truesdale; "you're homicidal at heart anyway!" He turned on Donna, wiping perspiration from his forehead. "Are you going to let him do it?" he shrilled. "Are you going to help him commit such a crime?"

The girl stared at him with a worried look in her blue eyes but said nothing.

"Come on, Truesdale," said Phillips, making an effort at a peaceful, persuasive tone. "It will be either their lives or ours if they spot us--and millions more if they get by. They'll be too desperate to think of us. Do you want to die?"

The instant he spoke the last words, he remembered the other's record and wished he had kept quiet. He saw, a strange, wild expression creep over Truesdale's features. It changed into a look of hateful cunning as the youth, began to sidle toward the door.

"I'm not afraid to die!" he boasted in a low-pitched but tense voice. "But how about you, Phillips? How about the big, brutal space engineer who is proud of smashing men's skulls against steel walls, who would like nothing better than to blow up a shipload of innocent people. How do you really know they're dangerous? But you don't care, do you?"

"Truesdale!" snapped Phillips. "Calm down!"

"I'll calm you down with me!" shouted the other hysterically. "I'll show you who's afraid to die!"

He ducked through the door toward which he had been backing. Phillips lunged after him, just barely missing a grip.

"On your toes!" he shouted over his shoulder to Donna, and turned on all jets.

But Truesdale, driven by his peculiar fury, not only stayed ahead as they raced along the corridor, but actually gained.

He was fifteen or twenty feet out in front as they reached the midway point. Phillips, expecting him to take refuge in the rocket room, was completely fooled when Truesdale leaped for the ladder in the vertical well. He stumbled, and grabbed a handrail to stop himself. The other was swarming upward. Phillips sprang to follow.

Hardly had he climbed half a dozen rungs, however, than he saw he was outdistanced. Truesdale's feet were already disappearing beyond the hatchway. Phillips waited for the airtight door to slam shut. It remained open....

Then a thrill of instinctive fear shot through him as he thought of what Truesdale might do--probably was doing at that very instant!

Throwing his feet clear of the rungs, he plunged back toward the deck, guided only by his hands brushing the sides of the ladder. As Phillips reached the junction of the passages, he kicked desperately away from the ladder. He landed with a thump that would have hurt had he been in a calmer state.

Rolling over toward the control room, he came to his feet in time to glimpse Donna looking out the doorway before a jarring shock floored him again.

The deafening roar of an explosion resounded in the corridor as a brilliant light was luridly reflected from somewhere behind him. The bewildering force hurled him at the deck; he saw he could not prevent his head from striking--

Phillips found himself on hands and knees, staring stupidly at the deck a few inches past his nose. As in a nightmare, he seemed to spend an eternity pushing himself painfully to his feet. Clutching a handrail, he finally made it.

He saw Donna kneeling in the doorway, hand to head. As he watched, the girl looked at her hand, and dazedly pulled out a handkerchief to wipe off the blood.

Then Phillips became aware of a high breeze in his face. Behind him, the sound of rushing air rose to a moan, then to a shriek. That shocked him to his senses.

"Button up!" he screamed above the noise, bringing his hands together in an urgent gesture understood by all spacemen.

As the girl staggered to her feet, he whirled and leaped toward the junction of the cross corridors. He wasted no time in a vain glance upwards--he knew what Truesdale had done. Only setting off the torpedoes' rockets in the enclosed turret compartment would have caused an explosion just severe enough to rupture the ship's skin; if the warheads had gone off, he never would have known it.

Diving headlong through the opening in the deck, he experienced a dizzying shift of gravity as he passed through the plane of the main deck. When he had his bearings again, he scrambled "up" the ladder toward the belly turret. By the time he got the airtight hatch open, he was beginning to pant in the thinning air. He pulled himself through at last, and sealed the compartment.

Phillips sucked in a deep, luxurious breath while he glanced about. This turret, he saw, was a duplicate of the other. He immediately located the intercom screen and called the control room. Donna's worried face appeared. "Where are you?" was her relieved inquiry.

Phillips explained what had happened. "The only thing," he concluded, "is to try it from here."

"I think they must have spotted the flash," Donna told him. "The instruments show a shift in their course."

"Blast right at them!" said Phillips. "We might get away with it if we're quick."

He turned away, leaving the intercom on. A few quick steps took him to the control panels in the bulkhead. Guided by his lessons in the other turret, and by faded memories of space school on Earth, he brought up two of the torpedoes. He checked the radio controls and ran the missiles into their launching tubes. As he worked, with nervous sweat running down into his eyes, he was aware of the intermittent jar of rocket blasts.

"Run 'em down!" he muttered, trying to steady his hand on the controls.

He had a hand at each panel, with the torpedoes poised viciously in the tubes, when he heard Donna's shout, shrill with excitement, over the intercom.

Instantly, he launched the missiles. He started the rockets by remote control, and scanned the screens for a sight of the other vessel.

For a moment, his view was confused by the expanding puff of air; then that froze, and drifted back to the hull, and he could see the stars.

* * * * *

Donna's voice, strained but coldly controlled, came over the intercom with readings from her instruments. He corrected his courses accordingly.

Then he saw the image of their target centered on one screen, so he concentrated on steering the other missile. He made the nose yaw, but was unable to locate anything on its screen.

"You're sending one of them too far above, I think," Donna reported.

"I have something wrong," he shouted. "I can't spot them at all for that one. The jets must be out of line and shooting it in a curve."

Nevertheless, he fired a corrective blast on the weight of the guess, before returning his attention to the first torpedo.

This one was right on the curve. He could see the massive hull of the cruiser plainly now. It was almost featureless until, as he watched, several sections seemed to slide aside.

The screen showed him a momentary glimpse of a swarm of small, flame-tailed objects spewing forth from one of the openings. Then the view went dark. "Interceptor rockets with proximity fuses," he muttered. "They'll be after us next, crazy-mean and frantic!"

Over the intercom, he heard Donna exclaim in dismay. He caught a fleeting sight of her face and realized that the situation must be torture for the girl, as for himself or any normal person of their civilization.

Cursing himself for an optimist, he raised two more of the missiles from the magazine. Hopping about like a jet-checker five minutes before take-off time, he made them ready. It seemed like hours before he got them into the launching tubes and blew them out into the void.

Again, he watched the other vessel appear ahead of his torpedoes, this time on both screens. Before the gap narrowed, he had a better opportunity to see the defenses of the cruiser in action.

A whitish cloud of gas was expelled from his target's hull, bearing a myriad of small objects which promptly acquired a life of their own. Both screens were filled with flashing, diverging trails of flame. Then--nothing.

"They're heading at us!" called Donna. "Hang on!"

Phillips had already pulled the switches to bring up a new pair of torpedoes. Hearing the urgency in Donna's tone, he leaped toward a rack of spacesuits and grabbed.

* * * * *

The next instant, he was pinned forcibly against the rack by acceleration, as Donna made the ship dodge aside. From one side, he heard a screech of grating metal. The fresh missiles must have jammed halfway out of the storage compartment.

It gave him a weird feeling of unreality; as he hung there helplessly, to see one of the screens on the bulkhead pick up something moving, gleaming, metallic.

"Donna!" he shouted hoarsely. "Let up!"

"I don't dare," she gasped over the intercom. "I lost them, but they were starting after us!"

"Let up!" repeated Phillips. "They're dead ahead of that wild shot of ours. Let me get to the controls!"

He dropped abruptly to the deck as the acceleration vanished. One leap carried him to the radio controls.

The metallic gleam had swelled into a huge spaceship. The cruiser was angling slightly away from the point from which he seemed to be viewing it. How soon, he wondered, would they detect the presence of his torpedo? Or would they neglect this direction, being intent upon the destruction of those who were attempting to frustrate their mad dash for Mars?

Phillips stood before the screen, clenching his fists. There was, after all, nothing for him to do but watch. The gleaming hull expanded with a swelling rush. Details of construction, hitherto invisible, leaped out at him. A crack finally appeared as a section began to slide back.

This time, however, there was no blinding flare of small rockets. The blacking out of the screen coincided with Donna's scream. "It hit!"

In the silence that followed, he thought he heard a sob.

"Oh, Phillips," she said, recovering, "we did it. They're--"

"Hang on," said Phillips. "I'll climb into a spacesuit and come forward."

He switched off the intercom and dragged a suit from the rack. It took him a good fifteen minutes to get the helmet screwed on properly and to check everything else. He realized that he was very tired.

He opened the exit hatch, seized the top of the ladder in his gauntlets as the air exploded out of the turret, and climbed back to the main deck.

Clumping forward through the airless corridor, he stopped to look into the compartment where he had left Brecken. He quickly slid the door shut again.

He found that Donna had sealed off the corridor just short of the control room by closing a double emergency door that must have been designed to form an airlock in just such a situation. He hammered upon it, and she slid it open from the control desk.

It closed again behind him, and he entered the control room through the usual door. The girl helped him to remove the suit and motioned him toward the screen.

* * * * *

Phillips regarded the scene without enthusiasm. The sight of the dead man had reminded him of what the compartments of that other vessel must look like by now. Its parts were beginning to scatter slowly.

He looked at Donna, and found her regarding him soberly. "What will they do with us now?" she asked.

She looked exhausted. He extended an arm, and she leaned against him. "You heard what Varret said," he told her.

"Yes, but will he keep his word? They might be ... ashamed of us, now that it's done. Even if they're not, I can't bear the thought of going back to Earth and having them stare at me!"

Phillips nodded. He remembered the morbid curiosity during his own trial, the crowds who had watched him with a kind of shrinking horror--and he had actually been responsible for saving a spaceship and its crew, had they cared to look on that side of the affair.

But he had killed. That was no longer the action of a normal human being, according to popular thinking.

"I guess you and I are the only ones who will understand one another from now on," he shrugged.

Donna smiled faintly, just as the signal sounded on the communication screen.

It was Varret, looking pale and strained. He listened to Phillips' account, including the deaths of Truesdale and Brecken, and apologized for his appearance. He had, he informed them, been unpleasantly ill when he had seen the explosion. "It was a terrible thing," Varret continued sadly, "but necessary. They were beyond reasoning with, and a deadly menace."

He pulled himself together and tried to hide his agitation by reminding them of his promise. He suggested that they consider their requests while his ship attempted to tow them in to Deimos.

Phillips glanced speculatively at Donna. They would be two outcasts, however much their deed might be respected abstractly, however much official expressions of gratitude were employed to gloss over the fact. He might as well take one chance more. "We have already decided," he said boldly. "I hear you are building a new space station on Deimos."

The old man nodded, surprised.

"We will ask for a deed to that moon, and a contract to operate the beacon and radio relay station," Phillips stated flatly.

Varret blinked, then smiled slightly in a sort of understanding admiration.

"Reasonable and astute," he murmured after a moment's hesitation. "I think I appreciate the motive. Perhaps, if that ship can be repaired and remodeled, we can include it so that you may make short visits to Mars."

He warned them to watch for the emergency crew he would send to their aid, and switched off.

Phillips then dared finally to turn and look inquiringly at Donna. Her smile was relaxed for the first time since they had met. "Nice bargaining," she said, and Phillips felt like the king of something larger than a tiny Martian satellite.
