In doing so, he may well have solved Washington’s most famous unsolved murder. Based on years of painstaking research and interviews, much of it revealed here for the first time, the author traces the key events and influences in the life of Mary Pinchot Meyer, including her first meeting with Jack Kennedy at the Choate School in 1936; her explorations with psychedelic drugs; her relationship with Timothy Leary; and finally how she supported the president as he turned away from the Cold War toward the pursuit of world peace. As we approach the 50th anniversary of President Kennedy’s assassination—and Mary Meyer’s—Mary’s Mosaic adds to our understanding of why both took place.
