Jack the Ripper, also known as Red Jack, was the name given to an infamous, anonymous 19th century serial killer notable for the murder of at least five prostitutes in the East End of London between August and November 1888. Ultimately Jack went uncaught and there were several theories on his identity including that he was in fact a she, a surgeon, and Queen Victoria's eldest grandson, the Duke of Clarence.
The scalpel he used for his killings was cursed with his psychic residue, and last known to have been taken to Bermuda at the turn of the 20th century.
