Montresor's greatest fear in "The Cask of Amontillado" is that he will be caught during his crime and be incarcerated for murder. So, he painstakingly details every facet of his plot against Fortunato. He fears that his servants may witness his actions, so he makes sure they will be enjoying the carnival festivities instead. He worries that Fortunato may not follow him into the catacombs, so he tempts him with a bottle of rare amontillado. Montresor fears that a quick murder will not do justice for the crimes committed against him, so he concocts a way to satisfactorily torture Fortunato emotionally as well. He worries that Fortunato's cries may be heard, but the depths of the catacombs will solve this problem--as well as any qualms about whether the body will ever be found.
