Gradually our surroundings became more residential. We passed wide, open doorways. These I checked automatically, but they offered no danger, only miscellaneous domestic scenes: four elderly women absorbed in a game of mahjong; a group of boys surrounding a television; a family at the supper table. We passed an old shrine, its red paint peeling in the tropical moisture. Incense from the brazier within pervaded my senses with the recollected emotions of childhood.

Karate reached the corner of the street and turned right. In this warren of dim alcoves and alleyways, I could easily lose him if he developed distance, and I increased my pace to stay with him. I turned the same corner he had gone past a moment earlier-and nearly ran right into him.

He’d turned the corner and stopped-a classic countersurveillance move, and hard to beat if you’re working solo. No wonder he’d been taking it easy: the tunnel stunt had been a false finish to the run, and I’d fallen for it. Shit.

I felt an adrenaline dump. Audio faded out. Movement slowed down.

Our eyes locked, and for a suspended second we stood totally still. I saw his brow begin to furrow. I’ve seen this guy, I knew he was thinking. At the hotel.

His weight shifted back into a defensive stance. His left hand pulled forward the left lapel of his jacket. His right reached toward the gap.

Toward a weapon, no doubt. Shit.

I stepped in close and grabbed his right lower sleeve with my left hand, pulling it away from his body to prevent him from deploying whatever he had in his jacket. With my right I took hold of his left lapel and thrust it up under his chin. His reaction was good: he stepped back with his left leg to regain his balance and open up distance, from which he might be able to employ something from his karate arsenal. But I wasn’t going to give him that chance. I caught his right heel with my right foot and used my fist in his throat to shove him back in kouchigari, a basic judo throw. His balance ruined and his foot trapped, he went straight back, his left arm pinwheeling uselessly. I maintained my tight hold on his right arm and twisted counterclockwise as we fell, keeping my right elbow positioned squarely over his diaphragm, nailing it hard as we hit the pavement.

I scrambled to his right side, raised my right hand high, and shot a hammer-fist toward his nose. His reflexes were good, though, despite the shock of hitting the ground. He turned his head and deflected the blow with his left hand.

Still, he was out of his element on the ground, and quickly made a mistake. Rather than dealing with the immediate threat-my dominant position and freedom to attack-he went for his weapon again. I swam my right arm inside his right and jerked it back into a chicken wing. He sensed an opening and tried to sit up, but I felt that coming. Using the chicken wing to arrest his forward momentum, I swept my left arm around his head counterclockwise, from front to back, locked my hands behind his near shoulder blade, and leaned back, the back of my arm pressing down against his face. The move bent his neck back to the limit of its natural range of motion and took his shoulder half out of its socket, but I went no further. I only wanted to make him comply, not kill him. At least not yet.

“Who are you working for?” I said.

In response, he only struggled. I put some additional pressure on his neck, but quickly relaxed it, lest he conclude that I was trying to finish him, in which case I couldn’t reasonably expect him to cooperate.

He got the message and the struggling stopped. Not likely that he practiced any kata that involved being held on the ground in a neck crank. “Je ne comprends pas,” I heard him say, his body tense in my grip.

Bullshit you don’t comprehend, pal, I thought. I just heard you watching CN fucking N.

“Pour… Pour qui travaillez-vous?” I tried asking.

“Je ne comprends pas,” he said again.

All right, the hell with it. I squeezed again, harder than before, holding the pressure a second longer this time before backing off.

“Last time,” I said in English. “Tell me who you work for or you’re done.”

“All… all right,” I heard him say, his voice muffled by my arm across his face. I leaned forward slightly to hear better.

As I did so, he arched into me and jerked sharply upward with his right arm, trying to get clear of the chicken wing, to reach whatever he had in his jacket. I shifted to the left and yanked the arm back hard. But his move had only been a feint, and as I shifted I saw, too late, that his true intention had been to reach for his belt with his other hand. Before I could stop him, in one smooth motion he had popped a button on the leather and yanked free the buckle, which was attached to a double-edged steel blade.

Fuck. Without thinking I arched savagely back, pressing my left forearm hard across the back of his neck and squeezing with the strength of both arms. There was a split instant of raw corporeal resistance, and then his neck snapped and his body spasmed in my arms. The knife clattered to the ground.

I laid him out on the pavement and quickly patted him down. My hands were shaking from the effects of adrenaline. I was suddenly aware of my heart, pounding crazily inside me. Damn, that had been a nice move. He’d nearly gotten away with it.

He was traveling light: no wallet, no ID. Just his hotel key in a pants pocket and there, in a shoulder holster, what he’d been reaching for when he saw me. A Heckler & Koch Mark 23. Attached to it, a Knights Armament suppressor, one of the two models H &K approves for the Mark 23.

A belt knife and a silenced H &K. I doubted that he just waltzed them through airport security on his way to Macau, although I supposed it was possible the security guards were too preoccupied with nail clippers and cuticle scissors to notice. Still, my guess was that the mysterious Mr. Nuchi had local contacts, and that the weapons had been waiting for him or were otherwise procured after he had arrived. I filed the thought away for later consideration.

There was nothing else that could tell me more about who he was or who had sent him. Or who he had been on his way to meet.

I stood and glanced around me. Left, right. Nothing. The street was graveyard still.

I moved off into the shadows, my head reflexively sweeping right and left as I walked, searching for danger. I left the weapons, having little use for them in the current operation and not wishing to contaminate myself with anything connected to what the police might find at the crime scene. After a while, my pulse began to slow.

Who the hell was he? Who had he been on his way to meet? I hated the feeling of knowing so little about him. A name-Nuchi-which might have been an alias. And a probable nationality. But no more.

But I supposed that, overall, it wasn’t a bad outcome. I was nearly certain that, regardless of who had sent him, Karate had been here to take out Belghazi. That was no longer a possibility.

And things certainly could have turned out worse. If he’d had that H &K out when I’d first turned the corner, instead of reaching for it afterward, it might have been me lying back there in the dark.

I stayed on the narrow streets, the dark alleys. My pulse slowed more. My hands settled. The buildings to either side seemed to grow taller, and the weak light dimmer, until I felt as though I was zigzagging along the channel of a steep ravine, a dark urban gorge cut through the faded concrete façades by a long-vanished river. The rusted fire escapes were escarpments of rock, the hanging laundry tangled vines, a lone sodium-arc roof light a yellowed, gibbous moon.

I made my way back to the hotel. By the time I reached the rear entrance, my heart rate was normal again. I started thinking ahead, thinking about Belghazi.
