Harry Bosch is facing the end of the line. Hes been put on the DROP
- Deferred Retirement Option Plan
- & given three years before his retirement is enforced. Seeing the end of the mission coming hes anxious for cases. He doesnt have to wait long. First a cold case gets a DNA hit for a rape & 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 councilmans son is found dead
- fallen or pushed from a hotel window
- & he insists on Bosch taking the case despite the two mens history of enmity. The cases seem to be unrelated; one leads to the discovery of a killer operating in the city for as many as three decades the other to a deep political conspiracy that reached back into the dark history of the police department...
