In "The Cask of Amontillado," the wicked Montresor uses verbal irony on a number of occasions as a way of masking his true intentions regarding the hapless Fortunato. He also uses verbal irony to express his immense pleasure at finally gaining revenge on the man who's alleged to have done him a thousand wrongs.
One example of this comes toward the end of the story. At long last, Montresor has finally exacted a most terrible revenge on Fortunato by walling him up alive inside the catacombs. As Fortunato realizes to his horror, this is not an elaborate joke on Montresor's part; he's about to be consigned to his final resting place.
