A missing girl. A ruthless crime gang. A man so evil he must be stopped at any cost. DI Ray Mason and PI Tina Boyd begin a desperate hunt for the truth that will take them into a dark and terrifying world of corruption and deadly secrets, where murder is commonplace, and nothing and nobody is safe.. When the bones of a 21-year old woman who went missing without trace in Thailand in 1990, are discovered in the grounds of an old Catholic school in Buckinghamshire, an enduring mystery takes on a whole new twist. Her boyfriend at the time, and the man who reported her missing, Henry Forbes, now a middle-aged university lecturer, comes forward with his lawyer and tells DI Ray Mason of the Met’s Homicide Command that he knows what happened to Kitty, and who killed her.
