Seventeen-year-old Catherine Morland is one of ten children of a country clergyman. Although a tomboy in her childhood, by the age of 17 she is "in training for a heroine" and is excessively fond of reading Gothic novels, among which Ann Radcliffe's Mysteries of Udolpho is a favourite. Catherine is invited by the Allens, her wealthier neighbours in Fullerton, to accompany them to visit the town of Bath and partake in the winter season of balls, theatre and other social delights. She is soon introduced to a clever young gentleman, Henry Tilney, with whom she dances and converses.
