a mob. Quinn flapped the red notebook nervously against his right thigh, stood on his tiptoes, and peered into the throng. Soon the people were surging around him. There were men and women, children and old people, teenagers and babies, rich people and poor people, black men and white women, white men and black women, Orientals and Arabs, men in brown and gray and blue and green, women in red and white and yellow and pink, children in sneakers, children in shoes, children in cowboy boots, fat people and thin people, tall people and short people, each one different from all the others, each one irreducibly himself. Quinn watched them all, anchored to his spot, as if his whole being had been exiled to his eyes. Each time an elderly man approached, he braced himself for it to be Stillman. They came and went too quickly for him to indulge in disappointment, but in each old face he seemed to find an augur of what the real Stillman would be like, and he rapidly shifted his expectations with each new face, as if the accumulation of old men was heralding the imminent arrival of Stillman himself. For one brief instant Quinn thought, “So this is what detective work is like.” But other than that he thought nothing. He watched. Immobile among the moving crowd, he stood there and watched.
With about half the passengers now gone, Quinn had his first sight of Stillman. The resemblance to the photograph seemed unmistakable. No, he had not gone bald, as Quinn had thought he would. His hair was white, and it lay on his head uncombed, sticking up here and there in tufts. He was tall, thin, without question past sixty, somewhat stooped. Inappropriately for the season, he wore a long brown overcoat that had gone to seed, and he shuffled slightly as he walked. The expression on his face seemed placid, midway between a daze and thoughtfulness. He did not look at the things around him, nor did they seem to interest him. He had one piece of luggage, a once beautiful but now battered leather suitcase with a strap around it. Once or twice as he walked up the ramp he put the suitcase down and rested for a moment. He seemed to be moving with effort, a bit thrown by the crowd, uncertain whether to keep up with it or to let the others pass him by.
Quinn backed off several feet, positioning himself for a quick move to the left or right, depending on what happened. At the same time, he wanted to be far enough away so that Stillman would not feel he was being followed.
As Stillman reached the threshold of the station, he put his bag down once again and paused. At that moment Quinn allowed himself a glance to Stillman’s right, surveying the rest of the crowd to be doubly sure he had made no mistakes. What happened then defied explanation. Directly behind Stillman, heaving into view just inches behind his right shoulder, another man stopped, took a lighter out of his pocket, and lit a cigarette. His face was the exact twin of Stillman’s. For a second Quinn thought it was an illusion, a kind of aura thrown off by the electromagnetic currents in Stillman’s body. But no, this other Stillman moved, breathed, blinked his eyes; his actions were clearly independent of the first Stillman. The second Stillman had a prosperous air about him. He was dressed in an expensive blue suit; his shoes were shined; his white hair was combed; and in his eyes there was the shrewd look of a man of the world. He, too, was carrying a single bag: an elegant black suitcase, about the same size as the other Stillman’s.
Quinn froze. There was nothing he could do now that would not be a mistake. Whatever choice he made—and he had to make a choice—would be arbitrary, a submission to chance. Uncertainty would haunt him to the end. At that moment, the two Stillmans started on their way again. The first turned right, the second turned left. Quinn craved an amoeba’s body, wanting to cut himself in half and run off in two directions at once. “Do something,” he said to
