It is a country house somewhere in England, just before the first world war. It is the day when the annual pageant is to be performed in the grounds of the house. The pageant is traditionally a celebration of English history, and is attended by the entire local community. The owner of the house is a widower Bartholemew Oliver a retired Indian Army officer. His sister Lucy, who is also living in the house is slightly eccentric but harmless. Oliver has a son Giles who has a job in the city and is restless and frustrated. His wife Isa is staying at the house with her two children and has lost interest in Giles. She is attracted to a local gentleman farmer Haines, although the relationship goes no further than eye contact. In the course of the day, a Mrs Manresa and her friend William Dodge turn up, and stay for the pageant. The pageant has been written by Miss Le Trobe, a strange and domineering spinster. The day is interspersed with events leading up to the pageant. Lucy Swithin fusses around making all kinds of preparations from the decorations to the food. Oliver frightens his grandson by jumping out at him from behind a newspaper, and then calls him a coward when he cries. Mrs Manresa flirts with Oliver and Giles and is clearly being provocative,and William Dodge is dismissed as obviously gay. The pageant takes place in the evening and is made up of three main parts. After a prologue by a child, the first scene is a Shakespearean scene with romantic dialogue. The second scene is a parody of a restoration comedy, and the third scene is a panorama of Victorian triumph based on a policeman directing the traffic in Hyde Park. The final scene is entitled "Ourselves", at which point Miss La Trobe shocks the audience by turning mirrors on them. The book ends quietly with life returning to normal.
