That wasn't exactly true. _One_ of them would have to come back. Marquis hoped that 4901 wouldn't catch on to the fact that he would have to be resurrected, but that Marquis never would. He hoped that 4901's mind was too foggy and dull to see through the complex plan. And that was the way it worked. Marquis explained. 4901 listened and smiled. It was the first time Marquis had ever seen a prisoner smile. He left what remained of the capsule of poison where 4901 could get it. During one of the next four eating periods, 4901 was to slip the poison into Marquis' food can. Marquis wouldn't know what meal, or what can. He had to eat. The bells had conditioned him that much. And not to eat would be an overt act of self-destruction. He wasn't conditioned not to accept death administered by another. And then, after an eating period, 4901 whispered to him. "You're poisoned. It was in one of the cans you just ate." "Great!" almost shouted Marquis. "All right. Now I'll die by the end of the next work period. That gives us this sleep period and all the next work period. During that time I'll dispose of you as I've said." 4901 went to his bed and the bells rang and the dark came and both of them slept. * * * * * Number 4901 resisted the conditioners enough to follow Marquis past his regular work room into the food-mart. As planned, 4901 marched on and stood in the steaming shadows behind the hydroponic beds. Marquis worked for a while at the canning machines, at the big grinding vats. Then he went over to 4901 and said. "Turn around now." 4901 smiled. He turned around. "Good luck," he said. "Good luck--to you!" Marquis hit 4901 across the back of the neck with an alloy bar and killed him instantly. He changed clothes with the dead man. He put his own clothes in a refuse incinerator. Quickly, he dragged the body over and tossed it into one of the food-grinding vats. His head bobbed up above the gray swirling liquid once, then the body disappeared entirely, was ground finely and mixed with the other foodstuff. Within eight hours the cells of 4901 would be distributed minutely throughout the contents of thousands of cans of food-concentrate. Within that time much of it would have been consumed by the inmates and Managers. At the end of that work period, Marquis returned to his cell. He went past his own bed and stopped in front of 4901's bed. The sleep bells sounded and the dark came again. This would be the final dark, Marquis knew. This time he had beat the game. The delayed-action poison would kill him. He had on 4901's clothes with his identification number. He was on 4901's bed. He would die--as 4901. The guards would finally check on the missing man in the food-mart. But they would never find him. They would find 4901 dead, a suicide. And they would put the body labeled 4901 in the tank, dissolve it into dissociated cells and they would subject those cells to the electro-magnetic field of 4901.
