It's time for a new head girl. There are plenty of candidates, but after a terrible accident, and an hilarious school play, the true leaders are revealed.

Pat breaks her arm and misses the first weeks of term. Will Pat be upset when new girl Amanda becomes Isabel's new best friend?

There'll be mischief at St Clare's!
