LAPD detective Rene Ballard and Harry Bosch work together to hunt the killer who is Bosch's 'white whale' - a man responsible for the murder of an entire family.

A year has passed since LAPD detective Renée Ballard quit the force in the face of misogyny, demoralisation and endless
red tape. Yet after the chief of police himself tells her she can write her ticket within the department, Ballard takes back
her badge, leaving 'the Late Show' to rebuild the cold case unit at the elite Robbery-Homicide Division.
For years, Harry Bosch has been working a case that haunts him but that he hasn't been able to crack - the murder of an
entire family by a psychopath who still walks free. Ballard makes Bosch an offer: come work with her as a volunteer
investigator in the new Open-Unsolved Unit, and he can pursue his 'white whale' with the resources of the LAPD behind
him.
The two must put aside old resentments to work together again and close in on a dangerous killer. Propulsive and
unstoppable, this new novel demonstrates once again why 'Connelly is the real deal' (Marilyn Stasio, New York Times
Book Review).
