This classic detective novel introduces Monsieur Lecoq, a cunning and resourceful French detective whose methods of investigation helped shape the modern detective genre. When a brutal murder occurs in the outskirts of Paris, Lecoq is called to the scene to unravel a complex case involving false identities, buried secrets, and a dangerous criminal underworld. As Lecoq pieces together the clues, the novel explores themes of justice, deception, and the art of detection. Emile Gaboriau (1833-1873) is an important figure in the history of detective fiction. A French journalist and novelist, he created the "roman policier" with a series of books involving private detective Monsieur Lecoq, who works logically. Lecoq was based on a real-life thief turned policeman named Francois Vidocq (1775-1857), whose memoirs mixed fiction and fact. Gaboriau's huge following was eclipsed by Arthur Conan Doyle's Sherlock Holmes. Interestingly, Holmes may have been at least partly based on another of Gaboriau's characters, consulting detective Father Tabaret, whose methods Monsieur Lecoq adopts in the first Lecoq book.
