I watched her for a minute, and then I looked away. My name is Jack Reacher, and once I was a military cop, with heavy emphasis on the past tense. I have been out nearly as long as I was in. But old habits die hard. I had stepped into the bar the same way I always step anywhere, which is carefully. One-thirty in the morning. I had ridden the A train to West Fourth and walked south on Sixth Avenue and made the left on Bleecker and checked the sidewalks. I wanted music, but not the kind that drives large numbers of patrons outside to smoke.

The smallest knot of people stood next to a place with half a flight of stairs leading up to its door. There was a shiny black Mercedes sedan parked on the curb, with a driver behind the wheel. The music coming out of the place was filtered and dulled by the walls but I could hear an agile bass line and some snappy drumming. So I walked up the stairs and paid a $5 cover and shouldered my way inside.

Two exits. One the door I had just come through, the other at the end of a long dark restroom corridor way in back. The room was narrow and about 90 feet deep. A bar on the left at the front, then some upholstered horseshoe benches, then a cluster of freestanding tables on what, on other nights, might have been a dance floor. Then the stage, with the band on it.

The band looked as if it had been put together by accident after a misfiling incident at a talent agency. The bass player was a stout old black guy in a suit with a vest. He was plucking away at an upright bass fiddle. The drummer could have been his uncle. He was a big old guy sprawled comfortably behind a small, simple kit. The singer was also a harmonica player and was older than the bass player and younger than the drummer and bigger than either one.

The guitarist was completely different. He was young and white and small. Maybe 20, maybe 5-foot-6, maybe 130 pounds. He had a fancy blue guitar wired to a crisp new amplifier and together the instrument and the electronics made sharp sounds full of space and echoes. The amp must have been turned up to 11. The sound was incredibly loud. It was as if the air in the room was locked solid. It had no more capacity for volume.
