Death stalks London... Police officer and magician's apprentice Peter Grant is more than used to dealing with suspicious deaths, but when a murder mystery leads him to investigate a party in the exclusive London neighborhood, he finds out that the huge mansions of the super-rich and famous hide a bloody past: thousands of people were hanged to death in the Tyburn tree. Magic has returned to town and it's time for Peter and his mentor, Inspector Nightingale, to patrol in search of the supernatural beings that are shedding blood through the most select streets of the English capital.
