Dan Brown and The Lost Symbol

I wanted Dan Brown's latest book for Christmas. Santa brought me a copy (in the guise of my eldest son). I have read and enjoyed all Dan Brown's novels so far. I also enjoyed this one.
The plot for The Lost Symbol is familiar Dan Brown formula: Robert Langdon, the hero, interpreting symbols and puzzles; a frantic race against time across a city - in this case Washington; a deranged religious killer; unlikely twists and turns in the plot; and a tense ending. Where this novel differs from the others is in two regards: firstly, the Freemasons play a central role in the plot. Brown has great sympathy for the Freemasons and portrays them as misunderstood good and enlightened men. The challenge as to why there are no women allowed is conveniently ignored. The second main departure is the overly long pseudo-religious sermonising to finish which is a bit of a yawn after the dramatic conclusion to the story.
For the Christian reader Brown, as a sceptic, still raises questions as to the authority and reliability of The Bible. He also generalises, in the guise of Robert Langdon - the author's mouthpiece, that all religions are fundamentally the same and lead to God who is inside us all. On a positive note he poses some worthwhile questions to consider about: the nature of faith; how we read the The Bible; how we view those of other belief systems and the nature of Truth. The crux of the matter remains however: Is Jesus who He said He was -"The Way The Truth and the Life" ?
