The Unauthorized Guide to the Facts behind Dan Brown’s Bestselling Novel — by Simon Cox
I’ve read the book and it was a bit of a disapointment. It is also not really complete according sources on the internet.
“Cox merely invites more mystifications by repeating the (now long dead in France) Priory of Sion myths and presenting them as mysteries” — Paul Smith
The book addresses a lot of the items from the “Da Vinci Code” as a kind of an encyclopedia. It does definately not answer a lot of questions and is a bit protective to Dan Browns book. It explains some of the historical facts but about the priory of sion is not told a lot. Also the fact that Pierre Plantard — who founded the Priory — was shown to be a criminal and a forger in a French Court in 1992. A bit of a shame and a waste of money.
