Edward Conlon tells the electrifying and suspenseful story of two NYPD detectives, Meehan and Esposito: one damaged and introspective, the other ambitious and unscrupulous. Meehan is compelled by haunting and elusive stories that defy easy resolution, while Esposito is drawn to cases of rough and ordinary combat. A fierce and unlikely friendship develops between them and plays out against a tangle of mysteries: a lonely immigrant who hangs herself in Inwood Hill Park, a serial rapist preying on upper Manhattan, a troubled Catholic schoolgirl who appears in the wrong place with uncanny regularity, and a savage gang war that erupts over a case of mistaken identity.
