"The Murders in the Rue Morgue" is a mystery story by Edgar Allan Poe published in Graham's Magazine in 1841. It has been recognized as the first modern detective story; Poe referred to it as one of his "tales of ratiocination". The story opens with a lengthy explanation of ratiocination. Dupin demonstrates his prowess by deducing his companion's thoughts as if through apparent supernatural power. The story then turns to the baffling double murder of Madame L'Espanaye and her daughter at their home in the Rue Morgue, a fictional street in Paris. According to newspaper accounts, the mother was found in a yard behind the house, with multiple broken bones and her throat so deeply cut that her head fell off when the body was moved. The daughter was found strangled to death and stuffed upside down into a chimney. The murders occurred in a fourth-floor room that was locked from the inside; on the floor were found a bloody straight razor, several bloody tufts of gray hair, and two bags of gold coins. Several witnesses reported hearing two voices at the time of the murder, one male and French, but disagreed on the language spoken by the other. The speech was unclear, and every witness admits that he does not know the language he claims to have heard.Paris natives Dupin and his friend, the unnamed narrator of the story, read these newspaper accounts with interest. The two live in seclusion and allow no visitors. They have cut off contact with "former associates" and venture outside only at night.
