Query: This book was disappointing.

Reading this book was very disappointing. McDonald spends the first three-quarters of the book writing about himself. There is no kind of evidence of any kind dealing with the JFK assasination. It is difficult to tell if this is a true story or not, some parts began to sound like a cheesy spy movie. It was horribly written, lacked facts or even a description of the assassination, and the interview with the supposed killer was very anticlimatic. McDonald runs around claiming he is searching for the killer. He speaks with his usual contacts and they lead him to this guy called Saul. The interview with Saul does not offer any sort of convincing argument that this guy was the assassin either. I was more disappointed with this book than any other I've read on the JFK assassination. I'd spend my money on a better book.
