In the middle of the night on March 11, 1980, the phone rang in Julia Reed’s Georgetown dorm. It was her boss at Newsweek, where she was an intern. He told her to get in her car and drive to her alma mater, the Madeira School. Her former headmistress, Jean Harris, had just shot Dr. Herman Tarnower, The Scarsdale Diet Doctor. Julia didn’t flinch. She dressed, drove to Madeira, got the story, and her first byline and the new American Gilded Age was off and running.
