One key element, the Priory of Sion which Brown claims as fact. for one example, is a debunked fraud.
thanks for that -- I dropped by the English-language section of the bookstore for lunch and yes, that's on the front page claiming that the Priory of Sion is real.
This is claimed to be something created in 1099 when actually it was created by Pierre Plantard in 1956.
To claim this as a "fact" on its first page is devious at best.
