When London's legal establishment is shaken to its foundation by the crucifixion of a retired Lord Chief Justice, Detective Chief Inspector Joelle Levy is tasked with finding his killer. With fifty years of potential enemies to choose from, only the identical murder of former solicitor Adam Blunt offers a ray of hope: what is it that connects these victims who met such a gruesome end? Assigned to the story from the start, news reporter Sarah Truman sets out to investigate on her own, not suspecting that the trail will lead straight back to her fiance Michael Devlin. A criminal barrister determined to prove the innocence of his own client, Michael is at first oblivious to the return of the murderous figure from his past, until tragedy strikes closer to home. Struggling with his grief and guilt and now caught up in a madman's terrible quest for revenge, Michael must race to bring the killer to justice - before it's too late.
