Query: Hidden or Recalled Evidence?

Jon King and John Beveridge offer some intresting theories for the murder of Diana, Princess of Wales; however, the book lacks focus and wanders from the Jews (BC) to the Stuart dynasty to a supposed plot to put Diana on the throne in order to fill up 400 pages. The authors often make a point, then recant or weaken it by offering other explanations. Some information was given by sources who could not prove their statements, so the book was given a "maybe, maybe not" quality. The whole book could have been summarized in a few pages without all of the extraneous elements thrown in. A bit "over the top" for my taste.
