In Poe’s detective stories “The Murders in the Rue Morgue” and “The Purloined Letter,” Dupin serves as a model of rational deduction. Dupin seems to have almost supernatural deductive ability in solving mysteries. Since Dupin’s use of reason to solve mysteries is central to these stories, determining Poe’s views on the nature of reasoning is critical to an understanding of their meaning.

Through this comment, Poe asserts that correct analysis can lead only to the sole true conclusion. The practice of resolution is thus the search for the single correct explanation of the evidence among the many alternatives, just as Dupin and the police search for the true location of the letter among all possible places it could be hidden. Dupin and the police, though, use different
