Là-bas.

Là-Bas, translated as Down There or The Damned, is a novel by the French writer Joris-Karl Huysmans, first published in 1891. It is Huysmans' most famous work after À rebours. Là-Bas deals with the subject of Satanism in contemporary France, and the novel stirred a certain amount of controversy on its first appearance. It is the first of Huysmans' books to feature the character Durtal, a thinly disguised portrait of the author himself, who would go on to be the protagonist of all of Huysmans' subsequent novels: En route, La cathédrale and L'oblat. - wikipedia
