In Jane Austen’s Northanger Abbey, the heroine is mesmerized by the scandalous gothic novel, The Mysteries of Udolpho. Readers, I read that novel. My paperback Oxford World’s Classics edition (1998) of The Mysteries of Udolpho is 679 pages long, not counting introduction and notes. That’s a lot of mysteries. I read this so you don’t have to. SPOILERS AHEAD.
