One rainy morning in June, two years after the end of WWII, a minor traffic accident brings together Eleanor Moskowitz and Patricia Bellamy. Their encounter seems fated: Eleanor, a teacher and recent Vassar graduate, needs a job. Patricia's difficult 13-year-old daughter Margaux, recovering from polio, needs a private tutor. Though she feels out of place in the Bellamys' rarefied and elegant Park Avenue milieu, Eleanor forms an instant bond with Margaux.
