Query: utter rubbish

Having read a lot of conspiracy theories over the last few years I can say without a doubt that this is probably one of the worst books I have ever read. Whilst some books create tenuous links supported by few actual facts, this author invents facts all on his own and then presents them as empirical research. I have no doubt that Mr Byrne has had an interesting time researching this book, and (as others have mentioned) there are some items of historical note presented in a highly readable way, this book should be taken no more seriously than Dan Brown - and has about as much a basis in fact as the aforementioned authors own books.In short, if this was sold as a work of fiction then it would be reasonably entertaining, as a conspiracy theory book it borders on lunacy, and considering it as a work of research should result in someone being incarcerated.
