Was John Kennedy’s death really the work of a lone assassin? What happened to Lord Lucan? Could Marilyn Monroe have been murdered? Who was the Fifth Man? Despite tireless police work, advanced technology and the attention of the media, the case files of many major crimes remain resolutely open.

          This volume examines twenty-three of these intriguing mysteries, bringing together all the available facts and examining each case objectively and at length. In a few instances, it has been possible to construct a scenario that fits the existing information, but in the final analysis, it may be that the truth about these deaths, disappearances and defections will never be revealed.
