POST 3--Inoder to bring the real picture to light -Let me tell you first that Dan Browns book is pure fiction!.What he wanted was readers and to tell you the fact ,he achieved it-Da Vinci code is the fiction that sold the highest number of copies,till date.To immerse a reader in his book ,he included a page called FACTS! in his work of pure fiction where he alleges the truth of two things
The first of which is a harmless fact,which tells the existance of Opus Dei,a catholic organization and their relegious practices (who cares!!!!!)
The second FACT!! is the foundation of his novel-He claims the existance of a secret organization called 'priory-of-sion'and of its alleged Grand Masters-Well,if that was indeed a fact then his book would have had some historical importance.
But fortunately or unfortunately -that is a hoax and since we cannot question a mans right to speech,his ideas have now reached millions of readers

The Holy Blood,Holy Grail
The Da Vinci Code

What is this 'Priory of sion'?--I give you two references to the 'priory of sion' which will undoubtedly reveal its fakeness
The priory of sion
Priory-of-sion.com
So there is no point in believing Dan Brown,Let me add as a fiction Da Vinci code is very thrilling to read!
