If you look carefully at the fine print on the back of some books, there is a classification or genre listed, largely (I think) to help the bookseller know where to shelve the volume. In the case of Dan Brown’s latest novel I think the genre should read “hyperbole” or perhaps “suspension of disbelief.”
That the central character has survived The Da Vinci Code and Angels & Demons, and is highly knowledgeable in the arcane symbols of the world means he ought to accept somethings on faith, right? No. Apparently he isn’t willing to believe what others tell him.
I finished The Lost Symbol only to see how it ended, and I skimmed some sections rather then reading them word for word.
