After three years away, Harry Bosch comes back to the LAPD to find a department that has changed around him — and gets assigned to the Open-Unsolved Unit, the squad that inherits the city's coldest murders. Partnered again with Kiz Rider, his first case is one of the worst: the 1988 killing of Rebecca Verloren, a sixteen-year-old girl taken from her bed and shot in the hills above her home.
A modern DNA match finally puts a name to the murder weapon — a small-time criminal with ties to a white-supremacist crew — but the deeper Bosch and Rider dig, the more they sense the original investigation was steered off course. As the case brushes against Bosch's old nemesis, Deputy Chief Irvin Irving, he has to weigh how far the department will go to protect itself, and how much he is willing to risk on his return.
The eleventh Harry Bosch novel is a patient, absorbing cold-case procedural about the crimes a city would rather forget — and the closers who refuse to let them stay buried.
