En Route is a novel by the French writer Joris-Karl Huysmans and was first published in 1895. It is the second of Huysmans's books to feature the character Durtal, a thinly disguised portrait of the author himself. Durtal had already appeared in LÃÂ -bas, investigating Satanism. En Route and the two subsequent two novels, The Cathedral () and The Oblate (), trace his conversion to Catholicism, an experience that reflects the author's own. As Huysmans explained: <blockquote>"The plot of the novel is as simple as it could be. I've taken the principal character of LÃÂ -Bas, Durtal, had him converted, and sent him to a Trappist monastery. In studying his conversion, I've tried to trace the progress of a soul surprised by the gift of grace, and developing in an ecclesiastical atmosphere, to the accompaniment of mystical literature, liturgy, and plainchant, against a background of all that admirable art which the Church has created."</blockquote>
