From the "grand duchess" of British mysteries, the twenty-second installment of the New York Times bestselling William Monk series. Commander William Monk has learned to live with the fact that he cannot remember the events of his life prior to a horrific carriage accident years ago. But when a ghost from his past, a man he has no recollection of, attempts to frame him for a series of murders, he must rely on the help of his wife Hester and his close friend Oliver Rathbone in order to free himself-from both the charges, and the demons that have haunted him since the accident.
