Stephen Whyatt, an uneasy man who has been taping his wife’s telephone conversations with her lover, comes to Harry Devlin’s law office wanting information about getting a divorce. But when Harry takes him on, he gets more than he bargained for. Becky’s boyfriend’s voice on the tapes is oddly familiar, and as he listens Harry begins to fear that more is at stake than adultery. Is it part of the story that Stephen’s sinister brother is scheming to sell the family business - which seems to mean more to Stephen than his marriage does? When adultery slides frighteningly toward a case of murder, a trespasser makes a shocking discovery: three dead bodies in a converted church. Events gather speed, and the police conclude it’s a case of suicide and double murder. But Harry thinks they have it wrong - and he must unmask the real killer before time runs out.
