A riveting bestseller from one of the UK's biggest thriller writers.

Harry Barnett is a middle-aged failure. Leading a shabby existence in the shadow of a past disgrace, he is reduced to caretaking a friend's villa on the island of Rhodes and working in a bar to earn his keep. Then a guest at the villa - a young woman he had instantly and innocently warmed to - disappears on a mountain peak.
Under suspicion of her murder, Harry stumbles on a set of photographs taken in the weeks before her disappearance. Obsessed by the mystery that has changed his life and determined to clear his name, he begins to trace back the movements and encounters that led to the moment when she vanished into the blue. The trail leads him back to England, to a world he thought he had left for ever - and a past he has tried desperately to forget.
