Dimsie is now engaged to Peter, but has come back to the Jane Willard Foundation as a temporary school secretary, to help the headmistress who has not been very well. But Miss Yorke has a secondary motive in enlisting Dimsie's help - she wants her to improve the 'tone' of the school which has been slipping since she left. Prompted by the tempestuous but good hearted Hilary Garth, Dimsie encourages some of the girls to restart her old Anti-Soppist League.

But, in so doing, Dimsie tangles with the wealthy and sophisticated prefect, Coral. Coral breaks school rules left, right and centre, but always surreptitiously, so she never gets caught, and, among other things, she encourages other, less-well-off girls to gamble more than they can afford to lose. The supercilious Coral also annoys Dimsie by bullying her protegee, Lintie Gordon. And when Coral locks Lintie in her study as a punishment for some innocent mischief done by Lintie's little dog, Jeems, Dimsie is furious. But with her usual good humour and skill at dealing with people, Dimsie ends the term by winning through, though not without some setbacks and excitement along the way.
