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 haze 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.
