Northanger Abbey, was the first of Jane Austen's novels to be completed for publication, though she had previously made a start on Sense and Sensibility and Pride and Prejudice. She also becomes friends with Eleanor Tilney, Henry's younger sister. Henry captivates her with his view on novels and his knowledge of history and the world. General Tilney (Henry and Eleanor's father) invites Catherine to visit their estate, Northanger Abbey, which, from her reading of Ann Radcliffe's Gothic novel The Mysteries of Udolpho, she expects to be dark, ancient and full of Gothic horrors and fantastical mystery.
