This was sanity now, but what had it been before when he was cheerfully destroying his future? It seemed to him that there were two halves to his brain, each wanting different things. For a moment the one that had controlled the day was gone, and he was sane again, but how long would that moment last? What sign had there been when it took control? Would he know it when it came again? He remembered that in the tube train that morning he and Pierce had had a half joking argument about the best short-and-merry life. One of the happy ones on the list had been the INC agent, because they spent so much of their lives working into smuggling gangs that they had all the pleasures and profits of being a crook and an honest man too. Was that where he had slipped his cog? Looking back on the things he had done that day he saw that much of it had fitted an abstract pattern of justice, as if he had been thinking of himself as an INC man. Or as if-- He thought of the things he had seen in his childhood that they had called zombies, and jeered at and tormented without fear of any retaliation or vengeance from their gray-faced victims. Imprisoned men--they looked normal--but they had been mentally imprisoned. Law-zombies, memorizing and following laws and being honest with a simple and terrifying literalness. He had not known that he had any capacity for terror. Bryce Carter. He had his name, his identity and his memory, and they were his own. Sometimes he had had nothing else, only the pride and strength of knowing his identity, that it was his and stronger than others, just as his hands were stronger, a thing they couldn't take from him. _Could they?_ There was a nightmare he had had more than once, that he remembered suddenly for the first time, with all its atmosphere of childish strangeness. The cop psychos were after him. He was trapped in a big room with lights and they had his head open and were chasing him around inside his head somehow, trying to catch him, and kill him, the him that lived in his mind. Would he know if it was gone? The black sharp-edged shadows of the crater walls were drawing across the landing plain outside, bringing to a close the two weeks of daylight, and the reflected sunlight was dimming in the room. He could hear the rumble of a heavy ship of a cargo fleet lowering in to a landing. His assistant was sitting quietly on the edge of the desk as he had been for some time, motionlessly watching the thin plume of smoke that rose from a cigarette in his hand. He was as still as if he were listening for some subtle sound far away. Rocket jets flashed an orange glow through the venetian blinds and fell in stripes of orange light across the dark young face. The brief rumble of a rocket take-off came, transmitted through the ground and the building. Smoke curling up from the cigarette was the only motion. "Roy, is Pierce your real name?"
