Crystals of frost puffed out as the water vapor left the air. Braigh's helmet appeared, then the whole spacesuited figure floated up before the spot where Tremont was watching. The highjacker dropped the magnet of his life line against the hull and started to turn around.

Tremont grabbed the edge of the hatch with one hand, yanked the magnet loose with the other, and kicked Braigh in the right area.

The spacesuited figure shot off, tumbling end over end, into the void. A startled squawk sounded over Tremont's receiver.

"See how you like it!" he snarled.

He ignored the begging of the suddenly frightened voice, and dived into the air lock. In seconds, he had the outer hatch shut and was nervously watching the air pressure building up on the gauge.

If they notice at all, they'll think it's Braigh coming back! he exulted.

He made it into the central shaft without meeting anyone. Pulling himself forward in the bulky suit was an awkward task, but well worth it for the expression on Peters' face when Tremont burst through the control-room hatch.

After dealing with the pilot in about two minutes, most of it spent in catching him, Tremont went back along the shaft and found Dorothy in her bunk. Before she could release the netting, he folded the bunk upon her and secured it to the hook. Only then did he allow himself the time to remove his helmet and make free of the ship's air.

"What are you going to do?" demanded the girl, rather shrilly.

Tremont realized that she must have seen the unconscious Peters floating outside in the shaft.
