Here was where the fire damage was obvious. There was a gash in the front wall where the firemen had axed through the entrance. Ash lay on the sewing machines and cutting tables, heavier toward the southwest corner, where the worst of the blaze had been, but sprinkled with a liberal hand where I stood, near the other end of the room. The big windows in the back had broken. Glass lay everywhere, even near the front of the room. How had it traveled so far? Pieces of window frames, chair legs, half-sewn U.S. flags—all these were strewn around, as if some giant playing dollhouse in here had a temper tantrum—she got tired of it, picked up all the pieces and dropped them any old how.

Marcena would have wanted as much material as she could get for her hot story; she would have tried recording Grobian and Mr. William while Bron loaded the forklift. So maybe she put her pen down near where they were standing.

And there it was, next to a sewing machine, lying against a pair of shears. I couldn’t believe it, casually set out on a tabletop in plain sight. Of course, if you didn’t know what it was you wouldn’t imagine it was a recorder—it was really quite a clever gadget.

I picked it up and examined it under my flashlight. It was not much bigger than one of those fat, high-end pens you see in pricey stationery shops. There was a USB port for attaching it to a computer and downloading it, and little buttons, with the universal squares and triangles of recorders—play, forward, reverse. There was also a screen about an inch long and a quarter inch wide; when I pressed the “on” switch, the screen asked if I wanted to play or record. I hit the play button.

“Her and me, we’re the two best on the team, but Coach, she’s always giving April the breaks.”

The voice belonged to Celine, my gangbanger. The machine was starting from the beginning of the file, the day Marcena had come with me to basketball practice. I was tempted to eavesdrop more on how the team saw me, but I fast-forwarded. Next, I was startled by my own voice: I was talking to the woman next to me at the By-Smart prayer meeting, asking about William Bysen. I forwarded again.

This time, Marcena’s clipped tones came tinnily into the room. “Look, put it in your jacket pocket, here. I’ve switched it on, but it won’t record unless people are talking within about six feet of it, so hopefully you won’t pick up a ton of useless background noise.”
