Emile Gaboriau was a 19th century French writer and journalist best known for his detective stories. L'Affaire Lerouge (1866) was his first detective novel. This novel introduced a young police officer named Monsieur Lecoq, who was the hero in three of Gaboriau's later detective novels. Monsieur Lecoq was based on a real-life thief turned police officer, Eugène François Vi docq. Le Dossier n° 113 (File No. 113) was published in 1867. The story begins with an item in a local paper that reads, "A daring robbery, committed against one of our most eminent bankers, M. Andre Fauvel, caused great excitement this morning throughout the neighborhood of Rue de Provence. "The thieves, who were as skilful as they were bold, succeeded in making an entrance to the bank, in forcing the lock of a safe that has heretofore been considered impregnable, and in possessing themselves of the enormous sum of three hundred and fifty thousand francs in bank-notes. "The police, immediately informed of the robbery, displayed their accustomed zeal, and their efforts have been crowned with success. Already, it is said, P. B., a clerk in the bank, has been arrested, and there is every reason to hope that his accomplices will be speedily overtaken by the hand of justice."
