The storys heroine is Catherine Morland, an innocent seventeen-year-old woman from a country parsonage. While spending a few weeks in Bath with a family friend, Catherine meets and falls in love with Henry Tilney, who invites her to visit his family estate, Northanger Abbey. Once there, Catherine, a great reader of Gothic thrillers, lets the shadowy atmosphere of the old mansion fill her mind with terrible suspicions.

Northanger Abbey is often referred to as Jane Austens Gothic parody.
