When Liverpool solicitor and detective Harry Devlin takes on a client who has been taping his wife's telephone conversations with her lover, he gets more than he bargained for. The first mystery is the identity of Becky's boyfriend; whose voice Harry finds oddly familiar. Then, as a case of adultery slides frighteningly into conspiracy to murder, a trespasser makes a shocking discovery: three dead bodies in a converted church. Who are they? Who has killed them, and why? Trapped in a maze where neither victims nor apparent culprit are who they seem to be, Harry must go into the dark places of the human heart to find the answers.
