The Night Fire

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.

Bosch takes the murder book to Detective Renee Ballard and asks her to help him discover what about this crime lit Thompson's fire all those years ago. As she begins her inquiries -- while still working her own cases on the midnight shift -- Ballad finds aspects of the initial investigation that just don't add up.
