II Nicholas Martin felt like a man suddenly thrust under an ice-cold shower. No, not cold—steaming hot. Perfumed, too. The wind that blew in from the open window bore with it a frightful stench of gasoline, sagebrush, paint, and—from the distant commissary—ham sandwiches. "Drunk," he thought frantically. "I'm drunk—or crazy!" He sprang up and spun around wildly; then catching sight of a crack in the hardwood floor he tried to walk along it. "Because if I can walk a straight line," he thought, "I'm not drunk. I'm only crazy...." It was not a very comforting thought. He could walk it, all right. He could walk a far straighter line than the crack, which he saw now was microscopically jagged. He had, in fact, never felt such a sense of location and equilibrium in his life. His experiment carried him across the room to a wall-mirror, and as he straightened to look into it, suddenly all confusion settled and ceased. The violent sensory perceptions leveled off and returned to normal. Everything was quiet. Everything was all right. Martin met his own eyes in the mirror. Everything was not all right. He was stone cold sober. The Scotch he had drunk might as well have been spring-water. He leaned closer to the mirror, trying to stare through his own eyes into the depths of his brain. For something extremely odd was happening in there. All over his brain, tiny shutters were beginning to move, some sliding up till only a narrow crack remained, through which the beady little eyes of neurons could be seen peeping, some sliding down with faint crashes, revealing the agile, spidery forms of still other neurons scuttling for cover. Altered thresholds, changing the yes-and-no reaction time of the memory-circuits, with their key emotional indices and associations ... huh? The robot! Martin's head swung toward the closed office door. But he made no further move. The look of blank panic on his face very slowly, quite unconsciously, began to change. The robot ... could wait. Automatically Martin raised his hand, as though to adjust an invisible monocle. Behind him, the telephone began to ring. Martin glanced at it. His lips curved into an insolent smile.
