The Prime of Miss Jean Brodie by Muriel Spark a brief summary.

At the staid Marcia Blaine School for Girls, in Edinburgh, Scotland, Miss Jean Brodie--teacher extraordinaire--is unmistakably, and outspokenly, in her prime. She is passionate in the application of her unorthodox teaching methods, in her attraction to the married art master, Teddy Lloyd, in her affair with the bachelor music master, Gordon Lowther, and--most importantly--in her dedication to her girls. And her girls--the students she selects to be her creme de la creme--are devoted to Miss …

…The time is the 1930s. And Miss Brodie, apparently unaware that many might find unacceptable her outspoken admiration for Mussolini and Hitler, revels in, exploits, and shares her prime, only to become a victim of her own irrepressible exuberance. In this "perfect book" (Chicago Tribune), Muriel Spark probes with consummate, compressed artistry the halcyon years of a remarkable woman, whose intelligence, wit, imagination, charm, and elegance--however misguided at times, however fatal--match those of her creator.
