Colonel Abel Pargiter visits his mistress Mira in a dingy suburb, then returns home to his children and his invalid wife Rose. His eldest daughter Eleanor is a do-gooder in her early twenties, and Milly and Delia are in their teens. Morris, the eldest brother, is already a practising barrister. Delia feels trapped by her mother's illness and looks forward to her death. Ten-year-old Rose quarrels with twelve-year-old Martin and sneaks off by herself to a nearby toyshop. On the way back she is frightened by a man exposing himself. As the family prepares for bed, Mrs Pargiter seems at last to have died, but she recovers.
