She becomes Miss Brodie's closest confidante Miss Brodie believes she has insight the other girls do not. She is both carefully observant of others but also devoted to her fantasies.

Sandy Stranger is one of the Brodie set and has a rich inner life. Miss Brodie attempts to manipulate one of her students into having an affair with him, and another student ultimately betrays her and gets her fired. She is also caught in a love triangle with two male teachers at the school, but the one she loves is married. Rather than get married, however, she is devoted to the girls she teaches. She believes she is in the "prime" of her life. Miss Brodie sees herself as a guide for the girls, and she confides everything about her life to them, from her travels to her relationships to her political beliefs. Miss Brodie is captivating to a set of girls in her class, who find her personal stories and opinions far more fascinating than the lessons they might be learning with another teacher. Her fiancé was killed in World War I and there is a shortage of marriageable men since so many others were killed as well. Jean Brodie is a teacher in her 30s at the Marcia Blaine School for Girls.
