First off, some good points about this book: There are many subjects covered here. From the well known ( JFK, Loch Ness monster, Bigfoot) to some lesser known theories ( FeeJee Mermaid, BlueBeard, Cardiff Giant ) All the subjects are broken down into descriptive bite-sized chunks of information, each grouped together with similar stories. There are inserts of photo's, sketches and images of real life documents that relate to each theory.
Now the not so good: While it can be considered admirable not to pander to every strange question or thought people might have about historical events with suspicious circumstances, there is sometimes an overpowering feeling with this book that the writers are poking fun at the very people that these books appeal to. People who question nothing and accept everything are not very likely to invest time and money into buying Conspiracy Theory books so to insult the intelligence of the genuinely curious is not a smart move and left me angry at times while reading this book. Many theories covered have very real facts and questions circling around them e.g Bermuda Triangle, Jack the Ripper, Pyramids, Roswell and to just bluntly deny these facts like this book does on many occasions doesn't help anything but only deepens the mystery of why some things are so vehemently denied by those in charge.
A good way to read this book is from a psychological stand point. If you believe in conspiracy theories ( and I'm guessing you do if you are considering buying this book) then do buy this book and read it with the state of mind being that there are people in this world who who lie and treat the public as fools expecting them to swallow everything that is fed to them. If you come at this book from that point of view you may find that this book is less about finding the truth but more about the rigidity of the mind of idiots who truly believe that WE are the idiots instead.
How wrong they are. Right?
