SHE was about 19. No older. Maybe younger. An insurance company would have given her 60 more years to live. I figured a more accurate projection was 36 hours, or 36 minutes if things went wrong from the get-go.

She was blond and blue-eyed, but not American. American girls have a glow, a smoothness, from many generations of plenty. This girl was different. Her ancestors had known hardship and fear. That inheritance was in her face and her movements. Her eyes were wary. Her body was lean. Not the kind of lean you get from a diet, but the Darwinian kind of lean you get when your grandparents had no food – and either starved or didn’t. Her movements were fragile and tense, a little alert, a little nervous, though on the face of it she was having as good a time as a girl could get.

She was in a New York bar, drinking beer, listening to a band, and she was in love with the guitar player. That was clear. The part of her gaze that wasn’t wary was filled with adoration, and it was all aimed in his direction. She was probably Russian. She was rich. She was alone at a table near the stage and she had a pile of A.T.M.-fresh twenties in front of her and she was paying for each new bottle with one of them and she wasn’t asking for change. The waitresses loved her.

There was a guy further back in the room, wedged on an upholstered bench, staring at her. Her bodyguard, presumably. He was a tall, wide man with a shaved head and a black T-shirt under a black suit. He was part of the reason she was drinking beer in a city bar at the age of 19 or less. It wasn’t the kind of glossy place that had a policy about under-age rich girls, either for or against. It was a scruffy dive on Bleecker Street, staffed by skinny kids trying to make tuition money, and I guessed they had looked at her and her minder and made a snap decision against trouble and in favor of tips.
