Montresor convinces Fortunato to accompany him into the cellar by concocting an elaborate ruse about a very rare cask of wine that he has recently acquired. He knows that Fortunato considers himself to be an expert in wines and appeals to his vanity by asking him to help him determine whether the wine is a genuine "Amontillado." He then makes a show of suggesting that he will ask a rival of Fortunato's, Luchesi, to help him instead. He knows that Fortunato--who is already very drunk--will be unable to resist his request and will follow him willingly to the cellar. Montresor then continues to suggest that Fortunato should turn back because of his health throughout their trip into the cellar. All of these strategies keep Fortunato from noticing that he is being led farther and farther into the cellar and ultimately to his demise.
