Haunted by her past, which she keeps carefully hidden, London homicide detective Eve West has buried herself in her work for many years. But when she stumbles into the midst of a covert police operation, with catastrophic consequences, she is suspended from duty, her reputation in tatters. Help comes from an unexpected source when John Duran -- a murderer whom she put behind bars some years earlier -- offers to provide proof that she was set up. In return, she must investigate a possible miscarriage of justice. Eve is in no position to refuse. But why is a hardened criminal like Duran so eager to help a fellow inmate convicted of the killing of a young woman? And why has he chosen Eve to look into the case? Teaming up with crusading journalist Dan Cooper, Eve begins to uncover disturbing flaws in the original investigation. As events spiral out of control and her past is brutally dragged to the surface, she realizes that she has been plunged into a case more complex and sinister than she ever imagined.
