A psychotic killer still stalks LA, but Harry Bosch hasn't given up. This is the twelfth Harry Bosch book by no.1 internationally bestselling crime writer Michael Connelly.

In 1993, when Marie Gesto vanished Harry Bosch was assigned the case. But the 22-year-old woman could not be found-dead or alive-and she haunted Bosch.

Thirteen years later, Harry Bosch, now in the Open-Unsolved Unit, gets a call. A man accused of two heinous killings is willing to come clean on several other murders. One, he claims, is that of Marie Gesto.

Bosch has to get close to a man he hunted-and hated-for thirteen years. But then Harry discovers that he and his partner missed a clue that could have prevented the nine murders that followed Marie Gesto's disappearance.
