The Bone Field (The Bone Field #1) by Simon Kernick
From the best-selling author of Stay Alive, The Final Minute and The Witness.
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.
So begins a hunt for the truth that will focus on a ruthless crime gang, a rich, dysfunctional family with a terrible past, and a highly ambitious man so cruel and ruthless that he must be brought down at any cost…
