New York Times bestselling author Charles Todd brings back Scotland Yard's Ian Rutledge, who must unravel an unsolved, old case before he can bring a murderer to justice.
In Cornwall an act of mercy is repaid by an arrest for murder. Four young women have been accused of a crime, and when an irate father calls in a favor at the Home Office, Scotland Yard is asked to review the case.
Dispatched to the scene, Detective Inspector Ian Rutledge is hard pressed to deal with the father of another young woman, who swears he witnessed the murder and demands justice. To clear the names of the accused, Rutledge will have to find the key to a much older mystery that was never solved and that still haunts the village to this day.
