The Adventure of the Eleven Cuff-Buttons — Hector Malot

According to Wikipedia: Hector Malot (May 20, 1830 - July 17, 1907) was a French writer born in La Bouille, Seine-Maritime. He studied law in Rouen and Paris, but eventually literature became his passion. He worked as a dramatic critic for Lloyd Francais and as a literary critic for L'Opinion Nationale. His first book, published in 1859, was Les Amants. In total Malot wrote over 70 books. By far his most famous book is Sans Famille (Nobody's Boy, 1878), which deals with the travels of the young orphan Remi, who is sold to the streetmusician Vitalis at age 10. Sans Famille gained fame as a children's book, though it was not originally intended as such.
