The Second Form at St. Clare's

The Second Form at St. Clare's is the fourth novel in the St. Clare's series of children's school stories by Enid Blyton. The series is about the boarding school adventures of twin girls Patricia and Isabel O'Sullivan. Their form mistress is now Miss Jenks and they no longer have to bear the severeness of the first form mistress, Miss Roberts - who is extremely sarcastic and firm but can be kind when she feels like it, a bit like Mam'zelle, the French teacher that used to teach and is still teaching the girls.
