An updated third edition of the true crime expose, with new evidence and never-before-seen government documents further corroborating the conspiracy to assassinate JFK’s last true love and trusted ally.

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? 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?

Drawing on years of painstaking research and interviews, much of it revealed here for the first time, author Peter Janney traces the most important events and influences in the life of Mary Pinchot Meyer-her first meeting with Jack Kennedy, her exploration of psychedelic drugs, and her support of her secret lover, the president of the United States, as he turned away from the Cold War toward the pursuit of world peace. Fifty years after President Kennedy’s assassination - and Mary Meyer’s - Mary’s Mosaic deepens our understanding of why both took place.

This third edition-the culmination of the author’s two-year, grueling battle for documents from the U.S. Army and the National Personnel Records Center-has been updated with a final chapter on the mysterious man who may be the key to uncovering the truth behind Meyer’s mysterious murder.
