Just a minor note to you. You've got it all wrong and you are passing off phrases from the Da Vinci code without knowing their content!
'Jacques Saunière staggered ... ' because if you remember what you read after that, he was shot. And if you expect a shot man to walk uptight like a military general and not stagger, there's something wrong with you.
Also the description of the killer is NOT given by Saunière, but is given by the author! Do you care to read and understand stuff before shooting off articles like that ? Frankly, YOUR opening lines of the article were so dunderhead that they put me off!
