Fan Casting Holmes: Crimes and Mysteries

Holmes is engaged by Inspector Lestrade to investigate the murder of Peter Carey, known as Black Peter, an ill-tempered whaling captain who was found impaled on the wall of his garden cabin with a whaling harpoon. The case is an adaptation of "The Adventure of Black Peter". This specific case likely takes place prior to the events of Sherlock Holmes versus Jack the Ripper, as the murder weapon in this case is displayed on the wall of 221B Baker Street, which largely takes place between September and November 1888.
