" At the outset of the second of these Hong Kong excursions, I noticed an Arab standing in the lobby of the Macau Mandarin Oriental as we moved through it. He was new, not one of Belghazi’s bodyguards. I noted his presence and position, but of course gave no sign that he had even registered in my consciousness. He, however, was not similarly discreet. In the instant in which my gaze moved over his face, I saw he was looking at me intently, almost in concentration. The way a guy might look, in a more innocent setting, at someone he thought but wasn’t entirely sure was a celebrity, so as not to appear foolish asking the wrong person for an autograph. In my world, this look is more commonly seen on the face of the “pedestrian” who peers through the windshield of a car driving through a known checkpoint, his brow furrowed, his eyes hard, his head now nodding slightly in unconscious reflection of the pleasure of recognition, who then radios his compatriots fifty meters beyond that it’s time to move in for the kidnapping, or to open up with their AKs, or to detonate the bomb they’ve placed along the road.
