The Cask of Amontillado is Edgar Allan Poe's short but enigmatic masterpiece. Set in an unnamed Italian city, we hear the story of how Montresor lures Fortunato through the catacombs into the Montresor family vault and there chains him up and bricks him in for eternity. Why he does it we will never know, but he does so with a casual savagery that is truly chilling.
