"A superbly creepy, twisty thriller about obsessive love, psychological torture, and the darkest chambers of the human heart." -The Times(UK) Naomi Jenkins knows all about secrets: three years ago something so terrible happened to her that she's never told anyone about it. Now, Naomi has another secret: her relationship with the unhappily married Robert Haworth. When Robert vanishes without explanation, Naomi knows he must have come to harm. But the police are less convinced, particularly when Robert's wife insists he is not missing. In desperation, Naomi decides that if she can't persuade the detectives that Robert is in danger, she'll convince them that he is a danger to others. Naomi knows how to describe the actions of a psychopath; all she needs to do is dig up her own traumatic past.
