sat next to her mother as the train clattered along the Long Island Rail Road. The train had pulled out from Pinelawn at 7:39 A.M. , a full three minutes late, she had noted with some dissatisfaction. But she had been pleased that the train had reached the other stations with no additional delays, and they were on schedule to pull into Penn Station at precisely 8:37, with a journey lasting exactly the projected fifty-eight minutes. Tracie found this pleasing.
    Being content at having fit the train’s progress into a neat pattern in her mind, Tracie counted the seats, the windows, and the slats on the luggage racks. She counted the passengers all along the way, keeping track of those who entered, those who left, and the luggage that each had stowed up on the racks. She counted the number of people wearing hats, those using headphones, and the number of people with each hair color. (She was distressed that she couldn’t quite classify one man’s hair as either red or blond. Her mother cast the deciding vote for blond, and all was well again.) She took each of the numbers and factored it, then figured out if it could be expressed as a sum of primes, and then found complex mathematical relationships among them, as well as between each one and the current day, month, and year.
    This occupied her mind for most of the forty-five minutes of the ride so far. At 8:32, right on schedule, the train’s brakes began to whine as it pulled into Woodside. She heard the familiar hiss and opening of doors, and Tracie mouthed the announcement of the station along with the recording. Things became disordered as people got up and others came in, and it took a moment for everything to settle down and Tracie not to become overwhelmed. The train started moving again, and she got busy with the task of mentally recording those who had gotten off the train and those who had gotten on. The person wearing a patterned knitted cap was gone, as was the one with short-cropped black curly hair and the one with the red-and-white striped beanie. Among the newcomers were a bald man and a younger guy whose hair was long and greasy.
    Tracie counted them up and tried to work out what, from her previous counts and calculations, had changed. Except that when she tried, not everything added up. Something was off about the new numbers, about the scene in that train car. Sometimes she just had the feeling that something was wrong, and it took a lot of thinking to figure out what it was. Anxiety welled up in her. They were nearing Penn Station. She only had six minutes, by her calculations, to figure out the puzzle, or else, in her mind, something very bad would happen. Her mom would say that it was only her OCD, that nothing really was going to happen. But to Tracie, it was real. If she didn’t find out what was wrong, she had the inescapable feeling that someone was going to die.
    She closed her eyes and went through the numbers in her head, number of passengers and hats and hair color, until she noticed that it was something about the baggage. She looked at each luggage item stowed on the rack above the seats, straining to see each piece, making a mental connection between each piece of luggage and its owner.
    There was one piece of luggage that didn’t belong to anyone on the train. It was a blue backpack that had belonged to the man with curly hair—the one who had gotten off at Pinelawn. He had forgotten it! The thought was distressing to Tracie, but she knew how to fix it. She pictured a line, like the ones she imagined connecting each piece of luggage to each passenger, stretching from the backpack, through a tiny crack in the doors, and all the way back to Pinelawn, to a faceless, curly-haired figure standing on the platform. The backpack now was connected to its rightful owner in her mind, and everything seemed fine again. Nobody was going to die because of her carelessness.
    She could feel the pull of the train’s deceleration, and then she heard the
