When two bodies are washed up in the Kentish marshes, Detective Chief Inspector Henry Johnstone is propelled into a disturbing investigation.

December, 1928. When two bodies are found washed up in the Kentish marshes, it doesn’t take long for DCI Henry Johnstone and DS Mickey Hitchens to identify at least one of them. Billy Crane was a known associate of Josiah Bailey, one of the East End’s most notorious gangsters. But what were the victims doing in this remote and desolate spot? Is it a set-up? A revenge attack? Or could this be the start of a vicious turf war?

If so, who would be brave enough to challenge Josiah Bailey, whose tentacles have a disturbingly long reach? With witnesses too frightened to talk, the two London detectives must dig deep into the past if they are to make headway in the investigation and stop the escalating violence.
