Letters from Whitechapel is a deduction and bluffing game set in 1888 London, where one player takes on the role of Jack the Ripper and the others play police detectives. Jack moves secretly on a map, choosing victims and escaping, while detectives patrol streets, gather clues, and attempt to arrest him. The game ends after four nights; Jack wins by taking five victims without being caught, or the police win by catching Jack.
