Book excerpt: HISTORY OF THE AMERICAS. De Mey received international appraisal for Cold Case Kennedy - 'Flip has written a very interesting book. I would recommend reading it.' Barry Ernest, author of bestselling JFK book The Girl on the Stairs. Lawyer and forensic auditor Flip de Mey has for years studied the files on the assassination of President John F. Kennedy. His research, based on the original documents, led to a startling and ground-breaking theory, which he described in Cold Case Kennedy. In a follow-up to that bestseller, The Lee Harvey Oswald Files, de Mey investigates exactly what part Oswald played in the Kennedy assassination. With the same attention to detail that enabled him to prove Kennedy was the victim of a conspiracy, he examines the files and presents new information derived from unique photographs of Oswald's rifle and contact with two of Oswald's friends. De Mey's conclusion is unambiguous: Oswald could not have killed Kennedy.
