When Mickey Haller is invited by the Los Angeles County District Attorney to prosecute a case for him he knows something strange is going on. Mickeys a defense lawyer one of the best in the business and to switch sides like this would be akin to asking a fox to guard the hen-house. But the high-profile case of Jason Jessup a convicted child-killer who spent almost 25 years on death row before DNA evidence freed him is an intriguing one - particularly since the DAs determination to re-charge and re-try him for the same crime seems doomed to failure. Eager for the publicity and drawn to the challenge Mickey takes the case with Detective Harry Bosch on board as his lead investigator. But as a new trial date is set it starts to look like hes been set up with the renewed prosecution merely a tactic to prevent Jessup from successfully suing the state and county for millions of dollars. To avoid humiliation Mickey and Harry are going to have to dig deep into the past and find the truth about Melissa Landy and what really happened to her all those years ago.
