Meet Detective Sophie Allen. She’s an expert on murder and violent crime. Her brilliant mind works tirelessly to put the most vicious criminals behind bars, but conceals dark secrets from her own past . . .

A young man’s mutilated body is found on top of the Agglestone, a well-known local landmark on Studland Heath. It seems that he was involved in a people trafficking and prostitution gang. But why is DCI Sophie Allen keeping something back from her team? Is it linked to the extraordinary discovery of her own father’s body, found at the bottom of a disused mine-shaft more than forty years after he disappeared?
