Jean Harris belonged to the last generation of Americans brought up to believe that nice girls get married. But her love affair with Dr. Herman Tarnower went on for fourteen years without a marital commitment. One night Jean Harris, the prim headmistress of an elite girls' school, shot the famous Scarsdale Diet doctor to death. Was she a jealous woman bent on revenge? Or the desperate victim of a Dr. Feelgood who kept her enslaved by drugs and passion? In this incredible book, acclaimed journalist Shana Alexander exposes the dark truth behind the killing, the high drama of a sensational trial, and the fate of a complex woman doomed by her love and her own desire.
