Catherine Morland, a young girl whose head is filled with Gothic romances. At Bath, she meets the Thorpe and Tilney families. Her brother James is attracted to Isabella Thorpe, and John Thorpe becomes attentive to Catherine. She, however, is more interested in Henry Tilney, a younger son, whose father invites her to his home, Northanger Abbey, under the mistaken impression that she is rich and will make a good match for Henry. Overcome by the thrill of being in a real abbey, Catherine makes several foolish blunders, even thinking that her host must have murdered his wife. The visit ends when General Tilney, learning that Catherine is not rich, asks her to leave and forbids Henry to see her. Yet Henry’s love proves strong enough for him to defy his father, and the lovers are finally married.
