As soon as the young cadet had left the smoking area around the wrecked tower, he realized that it was the only section of the small satellite that had suffered attack. Ahead, he could see the prisoners in their white suits crowding around the stabilizer air lock of the invading ship.

Tom dropped to his stomach and watched the knot of men. Suddenly the air-lock portal slid open. There was a loud cheer and the prisoners began scrambling aboard.

Tom knew he would have to move fast. Taking a dangerous chance, he rose to a half-crouch and dashed to one of the small white huts only a hundred feet away. With a final glance at the thinning crowd of escaping men around the ship, he ran straight for an open window, diving headlong through it.

Inside, Tom waited breathlessly for a shout or warning that he had been seen, but none came. He glanced through the window and saw that only seven or eight men remained outside the port. He turned away quickly and began searching the hut.

He found what he was looking for rolled up on the bed where its owner had used it as an extra pillow. He shook out the prison suit of white coveralls, stripped off his own blue cadet's uniform, and hurriedly put on the distinctive prison gear. It was a little large for him and he rolled up the sleeves and trouser legs, hoping no one would notice in the excitement. Then, with a deep breath, he stepped out of the hut into full view of the prisoners still left at the air lock.

"Hey, wait for me!" he yelled, running for the ship.

The men paid no attention in their haste to get aboard the ship. When Tom reached the air lock, there were only two left. He slapped the nearest man on the back.

"Pal, I've been waiting for this a long time!"

"Yah," the man answered, "me too!" Then he looked at Tom closely. "Say, I've never seen you around here before!"

"I just got in on the supply ship last week. They kept me in the tower for a while," Tom replied.
