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 eight, the girls are in the fifth form, about to reach the sixth, but they are not too old for tricks and escapades, jokes and excitement. Especially amusing is French girl Antoinette who, like her sister Claudine, doesn't always understand the ways of St. Clare's. Expect more mischief at St Clare's!
