Is it the end of the line for harry bosch?harry bosch is facing the end of the line. he's been put on the drop - deferred retirement option plan - and given three years before his retirement is enforced. seeing the end of the mission coming, he's anxious for cases. he doesn't have to wait long. first a cold case gets a dna hit for a rape and murder which points the finger at a 29-year-old convicted rapist who was only eight at the time of the murder. then a city councilman's son is found dead - fallen or pushed from a hotel window - and he insists on bosch taking the case despite the two men's history of enmity.the cases seem to be unrelated
