I smiled at him slowly. "Plenty of time," I said.

"What do you mean by that?" he asked. His eyes were suddenly sharp with suspicion.

"Oh, nothing," I said, shrugging. "A minute won't make a big difference will it?"

He studied me closely. My heart was beating against my ribs.

"I've changed my mind," he said abruptly, his fingers fumbling with the buckle that would release his arms. "I'll wait until later to do this."

"No you don't!" I said, my calm deserting me. I leaped around the tables. His fingers were trying desperately to open the buckle that would free his arms. I slapped them away and stood over him.

"This is for those hours of torture," I said, leering into his blank eyes. My fist crashed against the side of his jaw just in front of the ear. He sank back, limp and unconscious.

It was better this way. I was glad it had happened. Now I could be sure of what I did. I crossed the room to a bench and searched swiftly through drawers of tools until I found a wire cutter. In a moment I had clipped the blue coated wire where it was soldered to the red one. Quickly, with sure movements, I fastened the cover back on the case, threw the switch that sent electric current glowing through the cold filaments of tubes, and returned the wire clipper to its drawer. And by the time I had adjusted the two hoods into position over Dr. Leopold Moriss' head and that of the waiting robot form, the meters on the instrument panel showed that everything was ready for the final moment. The moment I had been looking forward to, working toward; when I could touch the switch that would begin the final act, completing my revenge.

My breathing was the only sound in the room as I stood for a moment surveying everything to be sure. I grinned into the doctor's closed eyes. It was too bad now that he wasn't conscious so that I could watch his fear and horror, so that he could know before I jabbed down on that switch what he had tortured me to discover.
