Romantic hero Auguste Dupin as

Dupin was a young gentleman of an excellent; indeed of an illustrious family, but, by a variety of untoward events, had been reduced to poverty. He read, wrote or conversed with his friend, until warned by the clock of the advent of the true Darkness.

The most important strains of Dupin’s character were his observation and ability to draw conclusions on the basis of the analysis of his supervision and remarks. He is one of the most important creations in history of a detective genre on two principal causes.

Undoubtedly, the image of Auguste Dupin had been created by Edgar Poe because of the influence of memoirs of Francois Vidocq. Dupin had specified only the basic version that the police had found the most authentic. The second cause is that Edgar Poe’s three short stories about him, which do not exceed more than one hundred pages, had been written when the detective genre did not exist yet. The researches of English writer Michael Harrison defined that Dupin had been named (and his image is partly based on) in honour of French aristocrat F. The story has been based on a real crime – Marie Roget's murder. That’s why we can explain that Poe called him “ Monsieur” only in the first story "The Murders in the Rue Morgue”, but “Chevalier” in the next two stories " The Mystery of Marie Roget “ and "The Purloined Letter ". He shows his tricks and comments them. It seems natural that Dupin had turned his talent to unearth different crimes.
