Who is Kate Fansler in the novel, In the Last Analysis?

Kate is an extremely independent woman who has been trained in old-fashioned grace and manners, yet who drinks martinis and has a series of lovers, albeit discreetly. She is the youngest child and only daughter of a wealthy family, who has rejected her older brothers' Wall Street values to pursue an academic career, though a family inheritance supplements her faculty salary. Like her creator, Carolyn Heilbrun, Kate lives and teaches in New York City.
