In 1993, Marie Gesto walked out of a Hollywood supermarket and vanished. Harry Bosch caught the case and never let it go, even after it went cold and the files followed him from desk to desk for more than a decade. Now, working the Open-Unsolved Unit, he gets the call he had stopped expecting: a man arrested with body parts in his van wants to confess, and one of the killings he is claiming is Marie Gesto's.
Raynard Waits offers to lead police to her remains in exchange for his life. But as Bosch revisits the old file, he finds a clue he and his partner overlooked years ago — an oversight that may have let a killer keep killing. Wracked by guilt and wary of a confession that seems too convenient, Bosch pushes into the case as political ambition and buried motives press in from every side.
The twelfth Harry Bosch novel is a tense, guilt-haunted procedural about the cases that never leave a detective — and the terrible cost of a single missed lead.
