"They held me in the tower for a month trying to make me take the psychograph rehabilitation. I got out when the blasting started."

"What were you on the Rock for?" asked Coxine. "You're pretty young to be sent to the Rock."

Tom thought desperately of a crime he could have committed that would send him to the prison asteroid. Suddenly he got an idea. He looked at Coxine and spoke in as harsh a voice as he could.

"Listen," he snarled, "I just broke Monkey's jaw for treating me like a kid. I hope you don't crowd me into fighting you by asking so many questions. Y'see I won't answer them and then you'll have to freeze me." Tom paused and tried to gauge Coxine's reaction. But he couldn't see a thing in the cold staring eyes. "And," Tom continued, "if you freeze me, you'll lose a better man than most of the scum in your crew!"

Coxine stepped forward and towered over the curly-haired cadet. When he spoke, his deep voice echoed in the deserted passageway.

"What was your rating as spaceman before you hit the Rock?" asked the big man.

Tom's heart raced. If he could get to the control deck or the radar bridge, he could send his signal easily. But he realized quickly that in either of these places he would be spotted almost immediately by Wallace or Simms. He had to stay away from them and wait for a later chance. Tom's mind raced.

"I was a gunner on a deep spacer," he drawled confidently. "I can take the space tan off a crawler's nose at a hundred thousand yards with anything from a two-inch to a six-inch blaster."

Coxine's eyes sharpened. "Where did you learn to use a six-incher? They're only on heavy cruisers of the Solar Guard!"

Tom could have bitten his tongue off. He had slipped. He thought quickly. "I was an enlisted spaceman in the Solar Guard."
