In the L.A.P.D.'s Open-Unsolved Unit, not many murder victims die almost a decade after the crime. So when a man succumbs to complications from being shot by a stray bullet nine years earlier, Bosch catches a case in which the body is still fresh, but any other evidence is virtually non-existent. Now Bosch and his new partner, rookie Detective Lucia Soto, are tasked with solving what turns out to be a highly charged, politically sensitive case.
