Mapp and Lucia is a 1931 comic novel written by E. F. Benson. It is the fourth of six novels in the popular Mapp and Lucia series, about idle women in the 1920s and their struggle for social dominance over their small communities. It brings together two sets of characters from three previous Benson novels: "Lucia" Lucas, Georgie Pillson and Daisy Quantock from Queen Lucia (1920) and Lucia in London (1927), and Miss Elizabeth Mapp and her neighbours from Miss Mapp (1922).
