I scrambled from the floor. Now, with the need for powerful action, the lack of gravity was a tremendous handicap. I went up with flailing arms into the air. Wyk fired his weapon, but it missed me, a soundless, dimly-white bolt. It hissed along the curving wall of the room. The smell of it was a stench in my nostrils.

I hit the concave ceiling, shoved down, and like a swimmer in water struck against the struggling bodies of Snap and the guard. The waving little shoulder arm with the weapon came at me.

Snap shouted, "Gregg, look out!"

I seized the little arm; it felt like the shell of a huge crab. For a moment we were all three entangled, floundering, unable to find a foothold. Then suddenly I felt Snap pulling me loose.

"We've got him!"

The brown-shelled body of Wyk sank away from us, hit the floor and lay still. I felt the floor under me, and Snap clutching at me.

In my hand I was clutching Wyk's little shoulder arm, with fingers still gripping the weapon. I had jerked it out of his shoulder socket. With a shudder I cast the noisome thing away. Whether Wyk was dead or not we did not know. He lay on his back; the hideous face stared upward.

"I cracked the shell," Snap gasped. "We've got to get out of here. Better try and get the girls loose now."

We wasted no further time on Wyk. Snap snatched several of his weapons and mechanical devices. We stowed them hastily in our pockets. One was like another to us; we could only guess at their uses.

"His shoes, Gregg. I can't get the damn things off him."
