Montresor (Left) has always disliked Fortunato (Right), but when he feels that Fortunato has insulted him, he decides that he must have vengeance to make it right.
Montresor finds Fortunato at the carnival, drunk and dressed as a jester. He convinces him to help test his new cask of Amontillado wine down in his family's catacombs.
Montresor leads Fortunato into the damp catacombs near his house, and Fortunato's cough seems to worsen once they enter. However, Fortunato refuses to turn back when Montresor offers.
As they reach the end of the cellar, Monteresor wraps chains around Fortunato and ties him to the wall. He then retrieves the masonry tools he had stashed within a pile of bones.
Montresor begins to create a wall, trapping Fortunato in the catacombs. Fortunato cried and screamed while the wall was being built, but Montresor keeps building.
Fortunato's cries turned to silence, and only the jingle of his costume's bells could be heard by Montresor as he sealed the final brick into the wall. Nobody saves Fortunato, and he is still left undisturbed when Montresor writes this story a half century later.
