A Renée Ballard and Harry Bosch Novel (abridged)

Renée Ballard works the night shift in Hollywood, beginning many investigations but finishing none as each morning she turns her cases over to day shift detectives. A once up-and-coming detective, she's been given this beat as punishment after filing a sexual harassment complaint against a supervisor. But one night she catches two cases she doesn't want to part with: the brutal beating of a prostitute left for dead in a parking lot and the killing of a young woman in a nightclub shooting.

Detective Renée Ballard is working the night beat - known in LAPD slang as "the late show" - and returns to Hollywood Station in the early hours to find a stranger rifling through old file cabinets. The intruder is retired detective Harry Bosch, working a cold case that has gotten under his skin. Ballard can't let him go through department records, but when he leaves, she looks into the case herself and feels a deep tug of empathy and anger. She has never been the kind of cop who leaves the job behind at the end of her shift - and she wants in.

Back when Harry Bosch was just a rookie homicide detective, he had an inspiring mentor who taught him to take the work personally and light the fire of relentlessness for every case. Now that mentor, John Jack Thompson, is dead, and his widow gives Bosch a murder book, one that Thompson took with him when he left the LAPD twenty years before—the unsolved killing of a troubled young man.
