Gaudy Night explores questions that were of pressing interest to Dorothy L. Sayers in 1935, but there is no aspect of her fiction that has travelled better into our own time. If anything, the novel is more timely today than when it was written, for the educated, professional woman is now more the norm than the striking exception. By addressing one of the important concerns of this century—the tentative emergence of women into all areas of society—in the timeless terms of realistic human psychology, Sayers created a classic novel. The book has survived many of its contemporaries in both the mystery genre and more ostensibly serious fiction because it is not a piece of social propaganda, but a work of art.
