playground shooting of a sixteen-year-old in Fort Tryon Park took him and Mayo over the Macombs Dam Bridge to Lincoln Hospital in the Bronx. The victim’s brothers were sitting in a small, dreary waiting room, three of them, mute and seething, visions of payback already playing in their eyes. They knew everything there was to know about what had gone down but he would have had better luck interviewing statues, and after twenty minutes of listening to himself talk, Billy got up from a coffee-stained couch with a blank notepad, just hoping that the aforementioned payback would occur after eight in the morning when he was heading up to Yonkers. It was on his way back to the nurses’ station that he first caught sight of the two homemade Missing posters push-pinned into the community announcements board, each featuring a low-resolution photo of Sweetpea Harris on purple printer paper that was bottom-fringed with tear-away phone number tabs, as if announcing the availability of a dog walker.
