Cracks

Set in the 1930s in a strict elite British boarding school called St Mathilda's, the story centres on a clique of girls who idolise their enigmatic diving instructor, Miss G, who had been a student at the same school where she now works. Di Radfield has a crush on Miss G, and is the firm favourite and ringleader of the girls who share her dormitory. When a beautiful and world wise aristocratic Spanish girl named Fiamma Corona arrives at the school Miss G's focus is shifted away from the other girls. It becomes a triangle: Miss G becomes obsessed with exotic Fiamma. Fiamma is disturbed by Miss G's somewhat overt advances and also openly disgusted by her hypocrisies and deceptions about her past; Di is terribly jealous and makes Fiamma's life hell.
