Harry is back, assigned to the LAPD's Open-Unsolved Unit with his former cop ally and partner, Kizmin Rider. These detectives are the Closers. They are thrown into a politically sensitive and dangerous case when a white supremacist is connected to the 1988 murder of a mixed-race girl. The police department has changed, but one thing hasn't--Harry's nemesis, Irving. The former deputy chief has been pushed from power and given a virtually meaningless new role. Full of vengeance, Irving calls Harry a "retread". He watches from the sidelines like an injured bear, hoping Harry will make a mistake...  Book 11 of series.

Harry Bosch has 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 are unrelated, but they twist around each other like the double helix of a DNA strand...

In 1993 Harry Bosch was assigned the case of a missing person, Marie Gesto. The young woman was never found - dead or alive - and the case has haunted Bosch ever since.

Thirteen years later Bosch is in the Open Unsolved Unit when he gets a call from the DA's office. A man accused of two killings is willing to confess to several other murders in a deal to avoid the death penalty. One of his victims, he says, is Marie Gesto. Bosch begins to crack when he realises he and his partner missed a clue back in 1993 which could have prevented the nine murders that followed the killing of Marie Gesto.

But as he tries to build a case and breach the impenetrable wall of silence in the local community, he finds he is taking a dragon by the tail - a dragon whose talons reach well beyond LA, and even the States.
