The Small House at Allington concerns the Dale family, who live in the "Small House," a dower house intended for the widowed mother (Dowager) of the owner of the estate. The landowner, in this instance, is the bachelor Squire of Allington, Christopher Dale. Dale's mother having died, he has allocated the Small House, rent free, to his widowed sister-in-law and her daughters Isabella ("Bell") and Lilian ("Lily"). When the novel begins Bernard, the squire's nephew and heir, brings his friend Adolphus Crosbie to Allington and introduces him to the family. Crosbie is handsome and well-regarded in London society.
