and I had purchased our tickets in advance so we would be able to follow him right through the wickets. Not that the attendant would notice one way or the other. At rush hour, they’re practically numbed by the hordes; you could flash anything, a baseball card, probably, and in you’d go.

    The light changed, and the crowds swept into one another like a battle scene from some medieval epic. An invisible radar I’m convinced is possessed only by Tokyoites prevented a mass of collisions in the middle of the street. I watched Kawamura as he cut diagonally across to the station, and maneuvered in behind him as he passed. There were five people between us as we surged past the attendant’s booth. I had to stay close now. It would be chaos when the train pulled in: five thousand people pouring out, five thousand people stacked fifteen deep waiting to get on, everyone jockeying for position. Foreigners who think of Japan as a polite society have never ridden the Yamanote at rush hour.

    The river of people flowed up the stairs and onto the platform, and the sounds and smells of the station seemed to arouse an extra sense of urgency in the crowd. We were swimming upstream against the people who had just gotten off the train, and as we reached the platform the doors were already closing on handbags and the odd protruding elbow. By the time we had passed the kiosk midway down the platform, the last car had passed us and a moment later it was gone. The next train would arrive in two minutes.

    Kawamura shuffled down the middle of the platform. I stayed behind him but hung back from the tracks, avoiding his wake. He was looking up and down the platform, but even if he had spotted Harry or me earlier, seeing us waiting for the train wasn’t going to unnerve him. Half the people waiting had just walked down Dogenzaka.

    I felt the rumble of the next train as Harry walked past me like a fighter jet buzzing a carrier control tower, the slightest nod of his head indicating that the rest was with me. I had told him I only needed his help until Kawamura was on the train, which is where he had always gone during our previous surveillance. Harry had done his usual good work in helping me get close to the target, and, per our script, he was now exiting the scene. I would contact him later, when I was done with the solo aspects of the job.

    Harry thinks I’m a private investigator and that all I do is follow these people around collecting information. To avoid the suspicious appearance of a too-high mortality rate for the subjects we track, I often have him follow people in whom I have no interest, who of course then provide some measure of cover by continuing to live their happy and oblivious lives. Also, where possible, I avoid sharing the subject’s name with Harry to minimize the chances that he’ll come across too many coincidental obituaries. Still, some of our subjects do have a habit of dying at the end of surveillance, and I know Harry has a curious mind. So far he hasn’t asked, which is good. I like Harry as an asset and wouldn’t want him to become a liability.

    I moved up close behind Kawamura, just another commuter trying to get a good position for boarding the train. This was the most delicate part of the operation. If I flubbed it, he would make me and it would be difficult to get sufficiently close to him for a second try.

    My right hand dipped into my pants pocket and touched a microprocessor-controlled magnet, about the size and weight of a quarter. On one side the magnet was covered with blue worsted cloth, like that of the suit Kawamura was wearing. Had it been necessary, I could have stripped away the blue to expose a layer of gray, which was the other color Kawamura favored. On the opposite side of the magnet was an adhesive backing.

    I withdrew the magnet from my pocket and protected it from view by cupping it in my hands. I would have to wait for the right moment, when Kawamura’s attention was distracted. Mildly distracted would be enough. Maybe as we were boarding the train. I peeled off the wax paper covering the adhesive and crumbled it into my left pants pocket.

    The train emerged at the end of the platform and hurtled toward us. Kawamura pulled a cell phone out of his breast pocket. Started to input a number.

    Okay, do it now.
I brushed past him, placing the magnet on his suit jacket just below the left shoulder blade, and moved several paces down the platform.

    Kawamura spoke into the phone
