Monsieur Lecoq is the creation of Émile Gaboriau, a 19th-century French writer and journalist. Monsieur Lecoq is a fictional detective employed by the French Sûreté. The character is one of the pioneers of the genre and a major influence on Sherlock Holmes (who, in A Study in Scarlet, calls him "a miserable bungler"), laying the groundwork for the methodical, scientifically minded detective. In French, "Monsieur" is "Mister" and his surname literally means "The Rooster".
In the person of armchair detective Tabaret, nicknamed Père Tireauclair, (lit. Father Bringer of Light, or "Old man Brings-to-light"), a title Lecoq himself will eventually inherit, Gaboriau also created an older mentor for Lecoq who, like Mycroft Holmes and Nero Wolfe, helps the hero solve particularly challenging puzzles while remaining largely inactive physically. In Tabaret's case, aid is dispensed from the comfort of his bed.
One inspiration for the character of Monsieur Lecoq came from a certain Eugène François Vidocq, a real life criminal who later became a policeman and eventually the first director of the Sûreté. Another influence was a character named Monsieur Lecoq, who appeared in Les Habits Noirs, written by Paul Féval, père who had been Gaboriau's employer in 1862.
Honoré de Balzac introduced the notorious Vautrin, also inspired by Vidocq, in Le Père Goriot in 1834. Also, Alexandre Dumas, père created the character of Monsieur Jackal, the mysterious head of the Paris Sûreté in Les Mohicans de Paris (1854–59).
Lecoq first appears in L'Affaire Lerouge, published in 1866, in which he is described as "formerly an habitual criminal, now at one with the law, skilful at his job". Lecoq plays only a minor role in this story, much of which is taken up by Mister Tabaret, an amateur sleuth nicknamed "Tirauclair" (French for "clarifier"), whom Lecoq recommends to help solve a murder.
Monsieur Lecoq appears in five novels and one short story written by Gaboriau and several pastiches.
