Edgar Allan Poe's "The Cask of Amontillado"

In Edgar Allan Poe’s “The Cask of Amontillado” the narrator presents himself in a way that calls to question his trustworthiness. Montresor presents farfetched ideas in his retelling of his story, rooms filled with human remains that are connected in some way to his wine cellar. Also, why wouldn’t Fortunato become suspicious at this sight, even if he was drunk? Another question of the narrator’s integrity is his reasons for telling the story. Is he confessing or simply telling a tall tale? Montresor is not a trustworthy man in his recount of the tale as seem in his deception of Fortunato. His integrity as a story-teller depends on his reasons for telling the story. If he is simply trying to entertain, then he still may be trustworthy. If he actually believes that the events happened actually happened, then his trust is in question.
I have never called into question the integrity of a narrator before. I have always assumed that everything in a story was true, or of course, if it was a tall tale, simply for entertainment. Poe writes in a way that leaves a lot of mystery. He progresses through the story by escalating the tension as the two characters search for the wine. He leads the reader to begin to suspect the narrator as an untrustworthy fellow, which turns out to be true. However, if one looks deeper into the text, the reader can also call to question the truth of the events being recounted, even if it is in the context of the story. I am speaking about the narrator telling his story, knowing if his account is completely true to himself or not. Of course the story is fiction, but within the context of the narrator’s mind, he may or may not be telling the truth. For the reasons listed in the first paragraph, I believe the narrator has exaggerated the scenes in the body filled room and the moving chains. Whatever the case, Montresor is certainly an entertaining narrator.
