Not many murder victims die a decade after the crime, so when Orlando Merced dies ten years after being shot, Bosch catches a case with a fresh body and virtually no evidence. Partnered with rookie detective Lucia Soto, Bosch begins to see political dimensions to the case - a case where, despite the seemingly impossible odds, failure to find the killer is simply not an option. But not only does Soto start showing signs of becoming a loose cannon, the one piece of evidence they have on the Merced shooting points in a shocking and unexpected direction that could unsettle the very people who want Bosch to close out the case. It's looking like Orlando Merced may not be the investigation's only victim-and that includes Bosch himself.
