Who really murdered Mary Pinchot Meyer in the fall of 1964? Why was there a mad rush by CIA counterintelligence chief James Angleton to locate and confiscate her diary? What in that diary was so explosive? Had Mary Meyer finally put together the intricate pieces of a plan to assassinate her lover, President Kennedy, with the trail ultimately leading to the CIA? And was it mere coincidence that Mary was killed less than three weeks after the release of the Warren Commission report? <br /> <br />These are the questions that author Peter Janney finally answers in a way that no one else ever has. 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—<em>Mary's Mosaic</em> adds to our understanding of why both took place. <br />
