Book excerpt: Scotland Yard's Duncan Kincaid and Gemma James face their most haunting case yet when the past devastatingly intersects with the present.... The call from Scotland Yard couldn't have come at a worse time for Detective Superintendent Duncan Kincaid. He has promised the weekend to Kit, the eleven-year-old son of his ex-wife. The son he never knew he fathered -- who doesn't yet know Kincaid's true identity. But Duncan's best intentions are shattered by an investigation that draws him in and swiftly consumes him. It seems to begin with the discovery of the body of a beautiful young woman in an East London park. But Kincaid and Sergeant Gemma James will discover that this case has long roots that reach far back into the past, and that resentments which should have been decades buried still have the power to hurt -- and maybe even the capacity to kill.
