Taking a desperate chance, I launched myself at his legs. His weapon roared over my head, just as I struck. I felt the hot gas from the thing beat against my neck; I caught the reeking scent of the smoke. Then we were both on the floor, and locked in a mad embrace.

Harbauer was a smaller man than myself, but he had the amazing strength of a Zenian. He fought viciously, using every ounce of his strength against me, striving to bring his weapon into use, hammering my head upon the floor, racking my body mercilessly, grunting, cursing, mumbling constantly as he did so.

But I was in better trim than Harbauer. I have never seen a laboratory man who could stand the strain of prolonged physical exertion. Bending over test-tubes and meters is no life for a man. At grips with him, I was in my own element, and he was out of his. I let him wear himself out, exerting myself as little as possible, confining my efforts to keeping his weapon where he could not use it.

I felt him weakening at last. His breath was coming in great sobs, and his long eyes started from their sockets with the strained effort he was putting forth. And then, with a single mighty effort, I knocked the pistol from his hand, so that it slid across the floor and brought up with a crash against a wall of the room.

"Now!" I said, and turned on him.


e knew, at that moment when I put forth my strength, that I had been playing with him. I read the shock of sudden fear in his eyes. My right arm went about him in a deadly hold; I had him in a grip that paralyzed him. Grimly, I jerked him to his feet, and he stood there trembling with weakness, his shoulders heaving as his breath came and went between his teeth.

"You realize, of course, that you're not going back?" I said quietly.

"Back?" Half dazed, he stared at me through the quivering lids of his peculiar eyes. "What do you mean?"
