Detective Harry Bosch, now in the Open-unsolved Unit, receives a call from the DA telling him a serial killer has confessed to several murders. Harry must interview the man about a case he couldn't crack involving the murder of a 22-year-old woman whose body was never found.

Just as he's on the verge of cracking an unsolved case, Detective Harry Bosch discovers an old clue that could have saved lives -- and the guilt begins to haunt him. In 1995, Marie Gesto disappeared after walking out of a supermarket in Hollywood. Harry Bosch worked the case but couldn't crack it, and the 22-year-old woman never turned up, dead or alive. Now Bosch is in the Open-Unsolved Unit, where he still keeps the Gesto file on his desk, when he gets a call from the DA. A man accused of two heinous killings is willing to come clean about several other murders, including the killing of Marie Gesto. Bosch must now take Raynard Waits's confession and get close to the man he has sought -- and hated -- for eleven years. But when Bosch learns that he and his partner missed a clue back in 1995 that could have led them to Gesto's killer -- and that would have stopped nine murders that followed -- he begins to crack.
