Tom sat up. "I jumped from the jet car at the last minute," he said. "I guess I must have bumped my head." He looked down at his torn uniform. "Wow," he said. "Look at me."

"Don't worry about it." Connel laughed. He turned to Lieutenant Slick who had just rushed up.

"Lieutenant, I want a complete check on the men who were standing outside the fence when that truck ran away."

"Yes, sir." The young lieutenant patted Tom on the shoulder. "Good work, Cadet," he said and started away.

Tom grinned his thanks at the young officer and struggled to his feet. "Sir," he said to Connel, "I think I should explain something about that truck."

"The truck!" cried Connel. He turned and called, "Lieutenant, come back here." The young officer turned back. "Go ahead, Tom," said Connel.

While Tom told his story of the truck having been parked near the gate, and having started to roll by itself, Connel and Slick listened intently. Quietly Devers joined them. Finally, when Tom had finished, Connel rubbed his chin thoughtfully and stared at the truck which was being examined by a swarm of guards.

A few moments later the sergeant in command reported to Connel that they had found a worn clutch plate that could have slipped and caused the truck to roll of its own accord, especially if the motor was turning over.

Connel nodded and then ordered, "Get the driver over here."

The man that had spoken to Tom about the secret project came forward under guard. He was thoroughly frightened and Connel was aware of it. "Relax, friend," he said. "I just want to ask you one question."
