Ann Radcliffe 
Mysteries of Udolpho 

This 1794 classic tells the tale of Emily St. Aubert, a young woman imprisioned within the towering Castle Udolpho by Signor Montoni. Stranded far from civilisation, she must seek a way out past the castles looming stone walls, and escape the clutches of her captor – all as strange, frightening events plague the castle’s every inhabitant.
