who went to the drug lord, who decided, among the three of them, that this was not an acceptable entrepreneurial scheme. The drug lord’s nephew had caught the first plane to South America and was probably hiding in the jungle, living on fish and berries. Moretti wasn’t so easily spooked, which probably speaks more to a lack of intelligence than an excess of nerve.

While I waited for him, I wandered about the platform, taking note of every post, every garbage can, every door-way. Busywork, really. I’d already scouted this station so well I could navigate it blindfolded, but I kept checking and double-checking.

My stomach fluttered. Not fear. Anticipation. I kept moving, trying to work past it. There was no more room here for anticipation than there was for fear. It was a job. It had to be approached with cool, emotionless efficiency. You cannot enjoy this work. If you do, you step onto the fast slide to a place you’ll never escape, become something you swore you’d never be.

I kept my brain busy with last-minute checks. There was one security camera down here, but an antiquated one, easy to avoid. I’d heard rumors of post-9/11 upgrades, but so far, this station had avoided them. Though I hadn’t seen a uniformed transit cop, I knew there could be a plain-clothes one, so I spotted the most likely suspects and stayed out of their way. Not that it mattered—in addition to the extra padding I was wearing a wig, colored contacts, eyeglasses and makeup to darken my skin tone.

I’d spent three days watching Moretti, long enough to know he was a man who liked routines. Right on schedule, he bounced down the subway steps, ready for his train home after a long day spent breaking kneecaps for a local bookie.

Partway down the stairs he stopped and surveyed the crowd below. His gaze paused on anyone of Italian ancestry, anyone wearing a trench coat, anyone carrying a bulky satchel, anyone who looked…dangerous. Too dumb to run, but not so dumb that he didn’t know he was in deep shit with the Tomassinis. At work, he always had a partner with him. From here, he’d take the subway to a house where he was bunking down with friends, taking refuge in numbers. This short trip was the only time he could be found alone, obviously having decided that public transit was safe enough.

As he scouted the crowd from the steps, people jostled him from behind, but he met their complaints with a snarl that sent them skittering around him. After a moment, he continued his descent into the subway pit. At the bottom, he cut through a group of young businessmen, then stopped beside a gaggle of careworn older women chattering in Spanish. He kept watching the crowd, but his gaze swept past me. The invisible woman.

I made my way across the platform, eyes straining to see down the tunnel, pretending to look for my train, flexing my hands as I allowed myself one last moment of anticipation. I closed my eyes and listened to the distant thumping of the oncoming train, felt the currents of air from the tunnel.

It was like standing in an airplane hatch, waiting to leap. Everything planned, checked, rechecked, every step of the next few minutes choreographed, the contingencies mapped out, should obstacles arise. Like skydiving, I controlled what I could, down to the most minute detail, creating the ordered perfection that set my mind at ease. Yet I knew that in a few seconds, when I made my move, I left some small bit to fate.

I inhaled deeply and concentrated on the moment, slowing my breathing, my pulse. Focusing.

No time to second-guess. No chance to turn back.

At the squeal of the approaching train, I opened my eyes, unclenched my hands and turned toward Moretti.

I quickened my pace until I was beside him. Tension blew off him in waves. His right hand was jammed into his pocket, undoubtedly fondling a nice piece of hardware.

The train headlights broke through the darkness.

Moretti stepped forward. I stepped on the heel of the woman in front of me. She stumbled. The crowd, pressed so tightly together, wobbled as one body. As I jostled against Moretti, my hand slid inside his open jacket. A deft jab followed by a clumsy shove as I “recovered” my balance. Moretti only grunted and pushed back, then clambered onto the train with the crowd.

I stepped onto the subway car, took a seat at the back, then disembarked at
