Who really murdered Mary Pinchot Meyer in the fall of 1964? Why was there a mad rush by CIA counter intelligence chief James Angleton to immediately locate and confiscate her diary? Had Mary Meyer finally put together the intricate pieces of a bewildering, conspiratorial mosaic of information that revealed a plan to assassinate her lover, President Kennedy, with the trail ultimately ending at the doorstep of the Central Intelligence Agency? And was it mere coincidence that Mary Meyer was killed less than three weeks after the release of the Warren Commission Report? Based on years of painstaking research and interviews, much of it revealed here for the first time, author Peter Janney traces some of the most important events and influences in the life of Mary Pinchot Meyer - including her explorations with psychedelic drugs and how she supported her secret lover, the president of the United States, as he turned away from the Cold War toward the pursuit of world peace. As we approach the fiftieth anniversary of President Kennedy's assassination - and Mary Meyer's - Mary's Mosaic adds to our understanding of why both took place.
