Philathea is justly proud of the famous Marriott bookshop, which is an extensive business that began in the reign of William III. She and her sisters, Vida and Salathiel, have old family names.
The Headmistress, Miss Heriot, firmly believes in treating people according to their merits, not their wealth and status. Brenda resents being mistaken for Beatrice Lowe by the caretaker, who knew Beatrice as a baby. In the future, she is always unpleasant to Beatrice.
Brenda has five friends (Lotty, Adeline, Linda, Lorna and Jessie) who follow her lead in forming a society for girls whose fathers are of high professional class, which they invite Dorcas to join - but not her friends. This insult to her friends leads to a fight between Dorcas and Brenda. At the subsequent prefects' meeting, Dorcas loses her position as team-captain of the hockey, but is reinstated after Philathea tells the prefects the truth behind the fight.
Philathea, as captain of the netball, chooses Brenda to play in the inter-form match. However, Brenda purposely pulls out on the morning of the match. Beatrice takes her place and helps Fifth Remove win the game, while Brenda is dropped from the team.
Brenda's parents are displeased with her rude behaviour at home. Brenda and her friends decide on a campaign to strike against the prefects, which widens the feud within the form. A prefects' meeting deprives the six of games for the rest of the term, and severe warnings are issued to Lotty and Adeline.
A fight between Brenda and Philathea culminates in an accident whereupon Philathea is nearly killed. As a result, Lotty is expelled and the rest suspended. Brenda is excluded despite her improved behaviour until Philathea returns and forgives her, and the feud is ended as the term finishes.
