The three Challoner sisters, Nan, Phillis, and Dulce, who live in a comfortable, gentrified cottage with their rather helpless and dependent widowed mother, discover that they are just like other girls (not well enough educated to become governesses) after the unfortunate investments made by their late father land the family in poverty. They dislike the idea of working as companions, since that would separate them. They become unlike other girls by resolving to exploit their talent for making their own clothes by setting up in business as dressmakers, although this will be regarded by their neighbours as a sad step down the social ladder. (Carrying parcels, for instance, is something that a lady is not supposed to do.) Their plight is particularly hard on Nan, who is being courted by their neighbour Richard Mayne, an only child who has grown up with them like a brother, but whose father has privately set his face against Dick's marrying Nan on the grounds that he might end up supporting the whole Challoner family. Nevertheless, the girls pursue their intention, and by the end of the novel the future looks bright for Nan and Dick, as well as for the others.
