Read Poe's, "The Cask of Amontillado" and at least three scholarly articles about the story. Write and submit a 2,000 word essay in which you cite the research in order to convince your reader of your understanding of the story.
The topic of your essay should be an argument proving that Monstresor has undergone a "transformation" in the 50 years since he murdered Fortunato and explaining why he underwent that transformation. (If you cannot agree that Montresor has changed, however, write an essay proving the opposite, that is, that Montresor did not undergo a transformation in the 50 years since the incident.)
Poe's story is easy to find online. One of the best ways is to go the Google and type in The University of Virginia Library, Electronic Texts, The Cask of Amontillado. You will have your own reactions to the story; you will want to use those reactions along with three or four scholarly articles to present your own literary essay. You'll provide in-text references and a works cited listing according to MLA guidelines. In addition to your own textbook, Owl Purdue online is a very good additional source of information about writing a research paper in the MLA or Modern Language Association's standard format.
