Villette begins with its famously passive protagonist, Lucy Snowe, age 14, staying at the home of her godmother Mrs. Bretton in "the clean and ancient town of Bretton", in England. Also in residence are Mrs. Bretton's son, John Graham Bretton (whom the family calls Graham), and a young visitor, Paulina Home (who is called Polly). Polly is a peculiar little girl who soon develops a deep devotion to Graham, who showers her with attention. But Polly's visit is cut short when her father arrives to take her away.
For reasons that are not stated, Lucy leaves Mrs. Bretton's home a few weeks after the Polly's departure. Some years pass, during which an unspecified family tragedy leaves Lucy without family, home, or means. After some initial hesitation, she is hired as a caregiver by Miss Marchmont, a rheumatic crippled woman. Lucy is soon accustomed to her work and has begun to feel content with her quiet lifestyle.
