dell arrived in lanburgh that same night and met the boys at the chief constable's office. There Inspector Clyde ushered them into the interrogation room and the young sleuths told about the capture of Timken.
"Great work!" the security chief exclaimed. "I'll want to question him myself before I go back to the States."
When Clyde left the room, Frank said, "I understand something important has come up on your end, too."
"Yes," Dell replied. "Our investigation has turned up a very interesting lead. Timken has been spending a lot of time with another Great Circle steward named Ross. We checked him out thoroughly and learned that he had a record for petty theft under another name. We suspect he's part of the Hexton-UGLI setup, but that he and Timken were working together."

"You mean they were double-crossing Hex-ton?" Joe asked.
"Yes. I doubt if Hexton would dispose of stolen goods in the clumsy way Timken has been doing."
"I see," said Frank. "These two manage to hold out a diamond here and there from the gang's robberies, then sell them."
"Right. We could pick Ross up on suspicion, of course. But I'd rather give him a little rope. Maybe we'll get a stronger case on him. Catching him first might make it easier to get Hexton."
"Where do we fit in?" Chet spoke up a bit fearfully.
Dell smiled. "Your assignment is to make a trip to the United States on our Flight 101. Ross will be steward. Use assumed names and occupations on the plane. Watch Ross and see if you can pick up any leads for SKOOL."
Joe grinned. "I'll feel like a secret agent on Flight 101!"
When Clyde returned, the Hardys told Dell about their aerial reconnaissance of Hexton's castle and of their efforts to think of some way to get inside.
The security chief laughed. "Sounds tough! But I'm betting on you." Dell told them that the next Flight 101 trip from Prestwick to New York was scheduled to depart in forty-eight hours.

"We'll have time to make another flight to the castle before we leave," Frank said. "I wonder if McHugh-"
Just then the telephone rang and the inspector picked up the receiver. "Hello. Inspector Clyde here! . . . Oh, it's you McHugh. . . . What? . . . Good heavens! That's incredible, I must say. Yes! The boys and I will start for the airport straight off!"
"What is it?" Frank asked.
"Somebody has cut the external control cables on McHugh's plane," he answered. "He wants to see us right away."
While Dell stayed behind, the inspector and the boys leaped into a police car and drove to the field. McHugh, in a furious mood, stood glowering beside his plane.
"Can you no' find the brigand who did this?" he shouted. "I'd like to get my hands on himl Here! Look at these!"
The boys examined the severed control cables, which dangled loosely from their connections at the tail and at the point where they entered the cockpit.
"Gee," Chet remarked, "they're cut clean in half."
"When did this happen?" Frank asked.
"It couldn't have been more than twenty minutes ago," McHugh replied. "While I was at the
120 The Secret Agent on Flight 101
plane, I was told there was a telephone call for me in the office, so I went there. But no one was on the other end of the line. When I came back here, I found the cables cut!"
"Obviously the call was a trick to lure you away from your plane," Frank observed.
Just then there were sounds of a loud commotion in the airport office. McHugh hurried toward the building, followed by the others.
When they entered, an aircraft mechanic was clutching a stocky man by the arm. Another man, who McHugh said was the airport manager, was questioning the stranger.
"What's going on here?" Inspector Clyde demanded. "I'm with the chief constable's officel"
"I found this fellow going through my clothes locker," the mechanic said. "And look at what he was carrying!" He held up an oversized pair of scissors.
"Those are metal cutters," McHugh stormed. "So this is the brigand who cut my cables!"
"I didn't cut anything!" the man growled.
"Let me at him!" McHugh bellowed, and started to roll up his shirt sleeves.
"Calm yourself!" the inspector ordered. He turned to the man. "What were you doing at the locker?"
"It was open. I thought I'd look around. That's all!"
"What about these cutters?"
A Furious Scot 121
"I found 'em! Besides, is there any law against carrying metal cutters?"
The boys gazed at the man. There was something familiar about him, Frank thought, but he could not recall where he had seen him before.
Inspector Clyde demanded that the stranger show him some identification. The man hesitated. Then he pulled a wallet from his pocket and handed it to the inspector. It contained an international driver's license in the name of Karl Arnold.
"Arnold!" Frank exchanged a quick glance with Joe. "The man Timken said was the fourth passenger in the helioplane the day I tried to stop its take-off!" he said to himself. Aloud he exclaimed, "You're one of Hexton's men!"
"Hexton? Never heard of him," the man insisted.
"Don't lie to us!" Joe snapped. "We know who you are!"
"You've got me mixed up with somebody else," Arnold retorted with a smirk.
"Let me shake it out of him!" McHugh bellowed.
The boys urged the pilot to relax. Then they suggested that Arnold be taken back to the chief constable's office to have Timken identify him. The inspector agreed to do this.
Arnold seemed unconcerned as they returned to lanburgh. When they reached the office, they
122 The Secret Agent on Flight 101
found Dell questioning Timken in the interrogation room. The steward was visibly startled when he saw Arnold.
"We ran across one of your friends at the airport," Frank announced.
Timken was obviously nervous. "Friend?" he said shakily. "What friend?"
"This man right here," Frank replied sharply, pointing to Arnold.
"Why-I-I never saw him before," the steward insisted. "I don't know him."
"Stop playing games!" Joe ordered angrily. "This man is Karl Arnold. You told us about him!"
Arnold's face flushed with anger, but he said nothing.
"That was somebody else," Timken said. "I've never seen this man before."
"Satisfied?" Arnold said indignantly. "Now, if that's all, I'll leave!" He turned and stormed out of the room.
"But we can't let him go!" Joe protested.
"I'm afraid we must." The inspector sighed. "We haven't any evidence to hold him on, but we'll keep track of him."
"The inspector's right," Frank assured his brother. "We have no witnesses who saw him cut the control cables. And there is no law against carrying wire cutters. If he'd resisted the temp-
A Furious Scot 123
tation to ransack the employees' lockers, he'd have got away altogether."
Dell looked discouraged as he and the boys left the interrogation room. "I didn't have much luck, either," he remarked. "Timken wouldn't tell me anything more than he told you."
"I suppose it's a pledge the UGLI men take," Frank said. "Besides, Timken is afraid of Hex-ton. That's why he wouldn't identify Arnold."
Minutes later, McHugh stalked into the chief constable's office. "I hope you have that Arnold fellow in jail!" he declared.
"We had to let him go," Frank admitted.
"What!" the pilot exclaimed. "Why, he's as guilty as a witch!"
"You don't have to tell us," Joe murmured.
"Can you repair the control cables?" Frank inquired.
"No," McHugh replied. "A new set will have to be made up special. It'll take two or three days before my tin bird will be flying again."
"Well," Frank said, "that washes out our plan for another reconnaissance flight before our trip. We'll have to wait until we get back."
The next day Dell, wishing the boys luck, returned to New York. The following morning the Hardys and Chet were on their way to Prestwick Airport, enthusiastic about their new assignment and the opportunity to spend a couple of days
124 The Secret Agent on Flight 101
at home before returning to Scotland. Soon they were winging their way westbound across the Atlantic on Flight 101.
Frank was using the name Bud Richmond and introduced himself to a few passengers as an announcer on station WHOX, meaning to him HOAX.
Joe had chosen to be Larry Walker, a student returning from a hike through Scotland. Throughout the flight, both Hardys kept an eye on the steward Ross. Chet, as a pro-football player named Chuck Brown, spent most of his time in the galley getting lemonade and asking Ross a hundred unimportant questions.
He was always being interrupted by a whiskered old man wearing dark glasses, who was seated near the galley. From time to time both the steward and stewardess had to assure him that the wings were not bending off, that the engines were not about to catch fire, and they were sorry that the tea they had served was weak.
The only incident out of the ordinary occurred after landing at Great Circle's base. The elderly man accidentally tripped Ross with his cane while disembarking from the plane. The steward fell flat in the doorway and the old man leaned down to help him up.
"So sorry," he said in a high, quavering voice.
The boys had arranged to have Jack Wayne meet them, and after clearing customs, were soon
A Furious Scot 125
on their way to Bayport. They were sorry not to have picked up any clues for SKOOL, but assumed Ross would be shadowed by agents.
The Hardys dropped Chet off at his farm, then drove quickly to their home. "Hello!" Mrs. Hardy cried out, and hugged her sons. "Did you see your dad?"
"No, Mother."
"He phoned a few minutes ago but didn't say where he's going. He's all right, though."
"Where did he phone from?" Joe asked.
"I don't know."
"You two boys look peaked," Aunt Gertrude spoke up, "but a few home-cooked meals will remedy that."
"It's good to be back," Frank declared.
The two women showed their disappointment when they heard that Frank and Joe would be returning to Scotland so soon.
"But we're sure eager for a shower and some American chow!" Joe said, grabbing the boys' two suitcases and bounding up the stairs. He set his bag on the bed and opened it to get a clean shirt.
"Hey! What's this?" he exclaimed, and picked up a carelessly hand-printed note from the top of his shirts. It read:
YOUR FATHER WARNS BE CAREFUL. GAME IS VERY DANGEROUS.
