Ann Radcliffe's orphaned heroine Emily St. Aubert finds herself imprisoned in her evil guardian Count Montoni's gloomy medieval fortress in the remote Apennines. Terror is the order of the day inside the walls of Udolpho, as Emily struggles against Montoni's rapacious schemes and the threat of her own psychological disintegration. A best-seller in its day and a potent influence on Sade, Poe, and other purveyors of eighteenth and nineteenth-century Gothic horror, The Mysteries of Udolpho remains one of the most important works in the history of European fiction. --from publisher description
