Hugo returned to political and social issues in his next novel, "L'Homme Qui Rit" ("The Man Who Laughs"), which was published in 1869 and painted a critical picture of the aristocracy. However, the novel was not as successful as his previous efforts, and Hugo himself began to comment on the growing distance between himself and literary contemporaries such as Flaubert and Émile Zola, whose realist and naturalist novels were now exceeding the popularity of his own work. His last novel, "Quatre-vingt-treize" ("Ninety-Three"), published in 1874, was about a subject that Hugo had previously avoided: the Reign of Terror during the French Revolution.
