What I liked most about this book was that the authors raise questions without answering them. Instead of asserting, as so many books of this type do, that (fill in name here) conspired to kill Bobby Kennedy, they admit that they don’t know. But they raise interesting questions. Was there a second gunman in the room when Kennedy was shot in June 1968 after winning the California primary? There is some circumstantial evidence that this may be the case.

Of greatest interest to me is the psychological state of the convicted killer, Sirhan Sirhan. Sirhan suffered from amnesia, and cannot recall what happened that night. Under hypnosis, it became clear to experts that he may well have been hypnotised before. A “Manchurian Candidate”, programmed to assassinate RFK? Not likely.

But in one of those meaningless but inevitable coincidences, Kennedy was brought to the hotel — and was staying at the home of — noted Hollywood director John Frankenheimer. You know, the man who directed the film, “The Manchurian Candidate”.
