Input: Question: How long did it take Hugo to write the novel that feature the fictional characters, Jean Valjean and Javert? Passage:In Victor Hugo's Les Misérables (1862), both main characters, the reformed criminal Jean Valjean and Police Inspector Javert, were modeled after Vidocq, as was the policeman Monsieur Jackal in The Mohicans of Paris (1854–1855) by Alexandre Dumas. He also was the basis for Rodolphe de Gerolstein, who secured justice in the serial newspaper novel The Mysteries of Paris of Eugène Sue in the weekly newspaper Journal des débats; and he was the inspiration of Émile Gaboriau for Monsieur Lecoq, one of the first scientific and methodical investigators who played the lead role in many adventures, who in turn was a major influence for the creation of Sherlock Holmes. It is also believed that Edgar Allan Poe was prompted by a story about Vidocq to create the first detective in fiction, C. Auguste Dupin, who appeared, for example, in the short story "The Murders in the Rue Morgue", which is considered the first detective story. Vidocq is also mentioned in Moby Dick ("Chapter 88: Schools and Schoolmasters") and White Jacket ("Chapter VI: The Quarterdeck Officers, etc.") by Herman Melville and Great Expectations by Charles Dickens.
