Though disparaged by literary critics of her day, Marie Corelli was one of the most popular novelists of the late Victorian and Edwardian periods. Wormwood (1890) is a lurid tale of unrequited love, betrayal, vengeance, murder, suicide, and addiction. The novel recounts the degeneration of Gaston Beauvais, a promising young Parisian man who, betrayed by his fiancée and his best friend, falls prey to the seductive powers of absinthe. The impact of Gaston’s debauchery and addiction on himself, his family, and his friends is graphically recounted in this important contribution to the literature of fin de siècle decadence. This Broadview edition includes a critical introduction and a generous selection of contextualizing documents, including excerpts from Corelli’s writings on art and literature, nineteenth-century degeneration theories, and clinical and artistic views on absinthe.
