On a late summer's Monday, Doctor Claire Roget takes up her new post of clinical psychiatrist at a secure psychiatric unit in Stoke-on-Trent. Six months earlier, her predecessor, Heidi Faro was brutally murdered by one of the inmates in the office she has now inherited. As Claire is adjusting to her new job, she becomes increasingly suspicious that someone else might have been involved in the murder. But Claire finds herself trapped in a vulnerable position: if she speaks she could be accused of a breach of medical confidentiality. But if she keeps silent she could be guilty of failing to protect the public against a dangerous individual.

A taut and gripping novel that seeks to explore the shifting boundary between sanity and insanity; this book is sure to play on your mind.
