At night rays of light shone through holes and gaps in the tarpaulin. Lord Vetinari wondered if Leonard was getting any sleep. It was quite possible that the man had designed some sort of contrivance to do it for him.

At the moment, there were other things to concern him.

The dragons were travelling in a ship of their own. It was far too dangerous to have them on board anything else. Ships were made of wood, and even when in a good mood dragons puffed little balls of fire. When they were over-excited, they exploded.

"They will be all right, won't they?" he said, keeping well back from the cages. "If any of them are harmed I shall be in serious trouble with the Sunshine Sanctuary in Ankh-Morpork. This is not a prospect I relish, I assure you."

"Mr da Quinn says there is no reason why they should not all get back safely, sir."

"And would you, Mister Stibbons, trust yourself in a contrivance pushed along by dragons?"

Ponder swallowed. "I'm not the stuff of heroes, sir."

"And what causes this lack in you, may I ask?"

"I think it's because I've got an active imagination."

This seemed a good explanation, Lord Vetinari mused as he walked away. The difference was that while other people imagined in terms of thoughts and pictures, Leonard imagined in terms of shape and space. His daydreams came with a cutting list and assembly instructions.

Lord Vetinari found himself hoping more and more for the success of his other plan. When all else fails, pray...

"All right now, lads, settle down. Settle down." Hughnon Ridcully, Chief Priest of Blind Io, looked down at the multitude of priests and priestesses that filled the huge Temple of Small Gods.

He shared many of the characteristics of his brother Mustrum. He also saw his job as being, essentially, one of organiser. There were plenty of people who were good at the actual believing, and he left them to it. It took a lot more than prayer to make sure the laundry got done and the building was kept in repair.

There were so many gods now... at least two thousand. Many were, of course, still very small. But you had to watch them. Gods were very much a fashion thing. Look at Om, now. One minute he was a bloodthirsty little deity in some mad hot country, and then suddenly he was one of the top gods. It had all been done by not answering prayers, but doing so in a sort of dynamic way that left open the possibility that one day he might and then there'd be fireworks. Hughnon, who had survived through decades of intense theological dispute by being a mean man at swinging a heavy thurible, was impressed by this novel technique.

And then, of course, you had your real newcomers like Amger, Goddess of Squashed Animals. Who would have thought that better roads and faster carts would have led to that? But gods grew bigger when called upon at need, and enough minds had cried out, "Oh god, what was that I hit?"

"Brethren!" he shouted, getting tired of waiting. "And sistren!"

The hubbub died away. A few flakes of dry and crumbling paint drifted down from the ceiling.

"Thank you," said Ridcully. "Now, can you please listen? My colleagues and I —" and here he indicated the senior clergy behind him — "have, I assure you, been working for some time on this idea, and there is no doubt that it is theologically sound. Can we please get on?"

He could still sense the annoyance among the priesthood. Born leaders didn't like being led.

"If we don't try this," he tried, "the godless wizards may succeed with their plans. And a fine lot of mugginses we will look."

"This is all very well, but the form of things is important!" snapped a priest. "We can't all pray at once! You know the gods don't like ecumenicalism! And what form of words will we use, pray?"

"I would have felt that a short non-controversial —" Hughnon Ridcully paused. In front of him were priests forbidden by holy edict from eating broccoli, priests who required unmarried girls to cover their ears lest they inflame the passions of other men, and priests who worshipped a small shortbread-and-raisin biscuit. Nothing was non-controversial.

"You see, it does appear that the world is going to end," he said weakly.

"Well? Some of us have been expecting that for some considerable time! It will be a judgement on mankind for its wickedness!"

"And broccoli!"

"And the short haircuts girls are wearing today!"

"Only the biscuits will be saved!"

Ridcully waved his crozier frantically for silence.

"But this isn't the wrath of the gods," he said. "I did tell you! It's the work of a man!"

"Ah, but he may be the hand of a god!"

"It's Cohen the Barbarian," said Ridcully.

"Even so, he might —"

The speaker in the crowd was nudged by the priest next to him.

"Hang on..."

There was a roar of excited conversation. There were few temples that hadn't been robbed or despoiled in a long life of adventuring, and the priests soon agreed that no god ever had anything in his hand that looked like Cohen the Barbarian. Hughnon turned his eyes up to the ceiling, with its beautiful but decrepit panorama of gods and heroes. Life must be a lot easier for gods, he decided.

"Very well," said one of the objectors, haughtily. "In that case, I think perhaps we could, in these special circumstances, get around a table just this once."

"Ah, that is a good —" Ridcully began.

"But of course we will need to give some very serious consideration as to what shape the table is going to be."

Ridcully looked blank for a moment. His expression did not change as he leaned down to one of his sub-deacons and said, "Scallop, please have someone ran along and tell my wife to pack my overnight bag, will you? I think this is going to take a little while..."

The central spire of Cori Celesti seemed to get no closer day by day.

"Are you sure Cohen's all right in the head?" said Evil Harry, as he helped Boy Willie manoeuvre Hamish's wheelchair over the ice.

"'Ere, are you tryin' to spread discontent among the troops, Harry?"

"Well, I did warn you, Will. I am a Dark Lord. I've got to keep in practice. And we're following a leader who keeps forgetting where he put his false teeth."

"Whut?" said Mad Hamish.

"I'm just saying that blowing up the gods could cause trouble," said Evil Harry. "It's a bit... disrespectful."

"You must've defiled a few temples in your time, Harry?"

"I ran 'em, Will, I ran 'em. I was a Mad Demon Lord for a while, you know. I had a Temple of Terror."

"Yes, on your allotment," said Boy Willie, grinning.

"That's right, that's right, rub it in," said Harry sulkily. "Just because I was never in the big league, just because —"

"Now, now, Harry, you know we don't think like that. We respected you. You knew the Code. You kept the faith. Well, Cohen just reckons the gods've got it comin' to them. Now, me, I'm worried because there's some tough ground ahead."

Evil Harry peered along the snowy canyon.

"There's some kind of magic path leads up the mountain," Willie went on. "But there's a mass of caves before you get there."

"The Impassable Caves of Dread," said Evil Harry.

Willie looked impressed. "Heard of them, have you? Accordin' to some old legend they're guarded by a legion of fearsome monsters and some devilishly devious devices and no one has ever passed through. Oh, yeah... perilous crevasses, too. Next, we'll have to swim through underwater caverns guarded by giant man-eating fish that no man has ever yet passed. And then there's some insane monks, and a door you can pass only by solving some ancient riddle... the usual sort of stuff."

"Sounds like a big job," Evil Harry ventured.

"Well, we know the answer to the riddle," said Boy Willie. "It's 'teeth'."

"How did you find that out?"

"Didn't have to. It's always teeth in poxy old riddles," Boy Willie grunted as they heaved the wheelchair through a particularly deep drift. "But the biggest problem, is going to be getting this damn thing through all that without Hamish waking up and making trouble."

In the study of his dark house on the edge of Time, Death looked at the wooden box.

Perhaps I shall try one more time, he said.

He reached down and lifted up a small kitten, patted it on the head, lowered it gently into the box, and closed the lid.

The cat dies when the air runs out?

"I suppose it might, sir," said Albert, his manservant. "But I don't reckon that's the point. If I understand it right, you don't know if the cat's dead or alive until you look at it."

Things will have come to a pretty pass, Albert, if I did not know whether a thing was dead or alive without having to go and look.

"Er... the way the theory goes, sir, it's the act of lookin" that determines if it's alive or not."

Death looked hurt. Are you suggesting I will kill the cat just by looking at it?

"It's not quite like that, sir."

I mean, it's not as if I make faces or anything.

"To be honest with you, sir, I don't think even the wizards understand the uncertainty business." said Albert. "We didn't truck with that class of stuff in my day. If you weren't certain, you were dead."

Death nodded. It was getting hard to keep up with the times. Take parallel dimensions. Parasite dimensions, now, he understood them. He lived in one. They were simply universes that weren't quite complete in themselves and could only exist by clinging on to a host universe, like remora fish. But parallel dimensions meant that anything you did, you didn't do somewhere else.

This presented exquisite problems to a being who was, by nature, definite. It was like playing poker against an infinite number of opponents.

He opened the box and took out the kitten. It stared at him with the normal mad amazement of kittens everywhere.

I don't hold with cruelty to cats, said Death, putting it gently on the floor.

"I think the whole cat in the box idea is one of them metaphors," said Albert.

Ah. A lie.

Death snapped his fingers.

Death's study did not occupy space in the normal sense of the word. The walls and ceiling were there for decoration rather than as any kind of dimensional limit. Now they faded away and a giant hourglass filled the air.

Its dimensions would be difficult to calculate, but they could be measured in miles.

Inside, lightnings crackled among the falling sands. Outside, a giant turtle was engraved upon the glass.

I think we shall have to clear the decks for this one, said Death.
