"The Cask of Amontillado" by Edgar Allan Poe is a short story first published in November 1846. Set during Carnival in an Italian city, it follows nobleman Montresor as he enacts revenge against fellow noble Fortunato for perceived insults and injuries. Told from the murderer's perspective, the tale lures Fortunato into the catacombs beneath Montresor's home with the promise of rare amontillado wine. What awaits is a carefully planned trap that ends in live burial. The story's central mystery lies not in detection, but in understanding Montresor's true motives for such extreme vengeance.
