DS Ronnie Brooks and DS Matt Devlin are forced to re-open a contentious murder case after a metal-detecting pensioner unearths a shallow grave by the side of the Thames. But their ensuing investigation leads them to question the conviction of Luke Slade by prosecutor James Steel several years earlier. After Luke is given leave to appeal, it is James who must revisit his past - one of his first cases for the Crown Prosecution Service.

And when the prosecution comes under threat, personal and professional loyalties are tested to the limit. Is Luke really guilty of murder? And why is he taking so much pleasure in the games of cat and mouse with James, whose career is on the line. And there is more murder to come...
