In Enid Blyton's bestselling series, the Naughtiest Girl and her friends make their own rules at their very unusual boarding school.
Elizabeth Allen is sent away to boarding school and makes up her mind to be the naughtiest pupil there's ever been. The school's strawberry plants have been vandalised and a lost blazer button at the scene of the crime leads straight to the Naughtiest Girl. It is hers, but how did it get there and why would anyone want to pin the blame on Elizabeth?
