About This Book

A young woman is found unconscious in a hospital parking lot with no memory of who she is or how she got there. Around the same time, two apparent suicides disturb the quiet city of Bath — a woman falls from a rooftop, and an elderly farmer is found shot. Detective Peter Diamond, never one to chase cases that aren't his to chase, has enough on his hands without adding a nameless amnesiac to the mix. But these seemingly unconnected threads have a way of pulling toward the same dark center, and Lovesey builds genuine unease from the simple, unsettling question: what happens when no one can tell you who you are?

What distinguishes this fifth Diamond novel is how Lovesey manages multiple storylines without ever letting the tension go slack. His plotting is intricate but never showy — the puzzle pieces arrive naturally, embedded in character behavior and quiet observation rather than contrived coincidence. Diamond himself remains one of crime fiction's more believable detectives: stubborn, occasionally wrong, and refreshingly human. Lovesey writes Bath with the same attention he gives his characters, making the city feel like a participant in the mystery rather than mere backdrop.
