"The Murders in the Rue Morgue" is a short story by Edgar Allan Poe published in Graham's Magazine in 1841. It has been claimed as the first detective story; Poe referred to it as one of his "tales of ratiocination". Similar works predate Poe's stories, including Das Fraulein von Scuderi (1819) by E.T.A. Hoffmann and Zadig (1748) by Voltaire.
C. Auguste Dupin is a man in Paris who solves the mysterious brutal murder of two women. Numerous witnesses heard a suspect, though no one agrees on what language was spoken. At the murder scene, Dupin finds a hair that does not appear to be human.
As the first true detective in fiction, the Dupin character established many literary devices which would be used in future fictional detectives including Sherlock Holmes and Hercule Poirot. Many later characters, for example, follow Poe's model of the brilliant detective, his personal friend who serves as narrator, and the final revelation being presented before the reasoning that leads up to it. Dupin himself reappears in "The Mystery of Marie Roget" and "The Purloined Letter".
Edgar Allan Poe è nato a Boston (USA) nel 1809 da una famiglia di attori girovaghi. Non ebbe modo di conoscerli approfonditamente poiché la madre morì quando ancora era un infante e il padre, alcolizzato, abbandonò la famiglia subito dopo la morte della moglie. Il piccolo Edgar fu quindi allevato da un ricco mercante di Richmond di nome John Allan.
Anche Edgar Allan Poe era solito deliziarsi dell'uso di alcool e gioco d'azzardo, motivo per cui John Allan lo estromise dal testamento.
