"Oh, well," said the man, "they ain't keepin' anybody there anymore!"

"Come on you guys," snarled a heavy-set man in the air lock above them. "We ain't got all day!"

Tom looked up, and without being told, he felt he was looking into the face of Bull Coxine. And when the other prisoner spoke, he was certain.

"Yeah, Bull," said the man. "Comin', comin'!" He reached up and Bull grabbed his outstretched hand. When Bull pulled, the man literally leaped through the air into the air lock.

"All right, space crawler," roared Bull to Tom, "you're next!" The big man stuck out his hand. Tom gulped. For one desperate second he thought of turning and running away.

"Well?" growled Bull. "You coming or ain't cha?"

"You're blasted right I'm coming," said Tom. "This is one time the Solar Guard is taking it on the chin. And, crawler, am I happy to see it!"

He grabbed Bull's hand and was lifted as easily as if he had been a feather. Coxine dropped him on the deck and turned away without a word to disappear inside the ship.

As he looked around, Tom suddenly felt a cold shiver run through his body. He felt as if he had signed his own death warrant. There was no mistake about it. The ship was the same one he had watched night after night at the exposition on Venus. And the names of the two owners exploded in his brain. "Wallace and Simms!"

He turned to jump out of the air lock, but it slid closed in front of him. He was trapped.
