I read this book in English ("The Unspeakable") and French. The French version release is quality, well translated and published with great care (nowadays it is unfortunately often have to be indignant at the mediocrity of writing books, full of spelling mistakes). This book argues convincingly in favor of the plot in the style of Oliver Stone film. We are led to believe this version so many strange elements support, even if the demonstration is not (yet) established. Read to know everything, or almost, on the murder of the young president and an extraordinary time that is roughly ended with his death, although Robert Kennedy was able to make the dream last a few years.
