The C. Auguste Dupin Trilogy

The C. Auguste Dupin Trilogy includes the three short stories featuring C. Auguste Dupin.
Le Chevalier C. Auguste Dupin is a fictional character created by Edgar Allan Poe. Dupin made his first appearance in Poe's The Murders in the Rue Morgue (1841), 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. Poe created the Dupin character before the word detective had been coined. The character laid the groundwork for fictional detectives to come, including Sherlock Holmes, and established most of the common elements of the detective fiction genre.
