An analysis of the alleged facts and speculations about the assassination of President John F. Kennedy. Parts of the book were first published in early 1964 as a series of articles in the French newspaper, L’Express. It was published in book form in May 1964 in the U.K. and France and was soon translated into many other languages, becoming a best-seller in 19 countries. The U.S. edition was published only later, and contained additions and revisions based on information that had come to light since the first publication, including the Warren Commission’s Report. The U.S. edition included a commentary on the Report.
