Le Chevalier C. Auguste Dupin (French: [oɡyst dypɛ̃]) is a fictional character created by Edgar Allan Poe. Dupin made his first appearance in Poe's 1841 short story "The Murders in the Rue Morgue", widely considered the first detective fiction story. He reappears in "The Mystery of Marie Rogêt" (1842) and "The Purloined Letter" (1844).
Dupin is not a professional detective and his motivations for solving the mysteries change throughout the three stories. Using what Poe termed "ratiocination", Dupin combines his considerable intellect with creative imagination, even putting himself in the mind of the criminal. His talents are strong enough that he appears able to read the mind of his companion, the unnamed narrator of all three stories.
"The Mystery of Marie Rogêt", often subtitled A Sequel to "The Murders in the Rue Morgue", is a short story by American writer Edgar Allan Poe written in 1842. This is the first murder mystery based on the details of a real crime. It first appeared in Snowden's Ladies' Companion in three installments, November and December 1842 and February 1843. Poe referred to it as one of his "tales of ratiocination".
"The Purloined Letter" is a short story by American author Edgar Allan Poe. It is the third of his three detective stories featuring the fictional C. Auguste Dupin, the other two being "The Murders in the Rue Morgue" and "The Mystery of Marie Rogêt". These stories are considered to be important early forerunners of the modern detective story. It first appeared in the literary annual The Gift for 1845 (1844) and soon was reprinted in numerous journals and newspapers.
