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 seven, Eileen's mother is the new Matron and Mam'zelle's niece, Claudine, joins St Clare's and causes havoc wherever she goes. The twins are enchanted by rebellious Claudine and her mad-cap plans, but will she last the term? Expect more mischief at St Clare's! Between 1941 and 1946, Enid Blyton wrote six novels set at St Clare's. This edition features the original text and is unillustrated.
