Dan Brown, for the love of God! No Pun intended, Dan Brown.
It attempts to be so freaking clever, but everyone that reads those books can always bust the riddles within half a second of reading them, while Tom Hanks (I've forgotten the character's name) bums around for 5 fecking chapters scratching his head like a brain dead neanderthal.
That and the formula for his books is exactly the same for each one.
Dude meets girl, girl has problem, meets confident, evil person appears, turns out the confident is evil, turns out the evil guy was being used, confident/real evil guy is foiled thereby solving girl's problem, dude bags girl.
This was the exact formula used for Angels & Demons, it was a test run to see if he could create a page turner, it worked. So then he just copies and pastes the same page turning, 3 page to a chapter formula and added some controversial subject matter pilfered from more talented authors and the Da Vinci Code was born.
