Mysteries of Paris

Popular 19th century French novel, in English translation. All six volumes in a single file. According to Wikipedia: "Joseph Marie Eugene Sue (20 January 1804 – 3 August 1857) was a French novelist… He was strongly affected by the Socialist ideas of the day, and these prompted his most famous works, the "anti-Catholic" novels: Les Mystères de Paris (10 vols., 1842-1843) and Le Juif errant (tr. "The Wandering Jew") (10 vols., 1844-1845), which were among the most popular specimens of the roman-feuilleton."
