Ann Ward Radcliffe 
The Mysteries Of Udolpho [EPUB ebook] 

The Mysteries of Udolpho follows the fortunes of Emily St. Aubert who suffers, among other misadventures, the death of her father, supernatural terrors in a gloomy castle, and the machinations of an Italian brigand. Often cited as the archetypal Gothic novel, The Mysteries of Udolpho, along with Radcliffe’s novel The Romance of the Forest, plays a prominent role in Jane Austen’s novel Northanger Abbey, in which an impressionable young woman, after reading Radcliffe’s novel, comes to see her friends and acquaintances as Gothic villains and victims with amusing results.
