Reaching the floor, they were met by four running figures in space suits. The boys recognized Kalmus and his three companions in a desperate hurry.

Rock lashed out boldly at Kalmus who was rushing at him. He heard the big fellow groan over his suit radio as the blow landed. But then Rock was charged by Jack Judas. He was lifted off the floor and, because of his helplessness when not in contact with it, was sent crashing heavily against the wall of the corridor.

Rock scrambled down off the wall to resume the battle. Shep was courageously taking on all four of their attackers. Rock leaped into the middle of it all, swinging fiercely. Another blow sent him careening into the wall. Shep was flat on the floor now.

Expecting no mercy from the victors, Rock was amazed to see the four withdraw from the fight and run off down the corridor in the direction they had been heading in before. Rock and Shep tiredly climbed to their feet.

“They weren’t after us!” Shep gasped. “They were just trying to get away!”

“They’re heading for the lifeboat rockets, I guess,” Rock panted. “They looked scared to death!”

“Let’s get to the fellows!” Shep said.

They hurried along to the main control room. It was empty, so they moved farther along to the navigation room. The door was locked and from inside there came the sound of beating fists. With their heavy space boots Rock and Shep began kicking the light metal door with passionate vigor. Finally they tore the lock loose and the twisted door swung inward.

Sparky, Ed, and Johnny were sagging against the far wall, their eyelids half-closed. Leo was giggling strangely and chattering as if enjoying himself. Sparky kept crying out, “I can’t hear!”

Only Hugh appeared normal. It was he who had been beating on the door. His face was red with fright and shiny with sweat.
