Schooldays at St Clare's are never dull for twins Pat and Isabel O'Sullivan in Enid Blyton's much-loved boarding school series.
In book four, the twins have made it to second form. New girls Gladys and Mirabel have great talents for acting and music, and Elsie, the form's unpopular Head Girl, learns to be less spiteful.
Expect more mischief at St Clare's!
