The Da Vinci Code post 1

The book starts of by introducing a Harvard profesor named Langdon. During this time he is in france giving presentations. One night someone shows up to his hotel room trying to talk to him he completely ignores him and tells him to come back tomorrow because he is tired. The night after this another person visits him he can't deny him since he is part of the french equivalent to the C.I.A. Langdon is then taken by force because he has to help solve a mistery. The man that had previously tried to contact him was Saunière. Saunière  had been found dead inside the Louvre. That wasn't it though he was found naked and with symbols drawn on him with his own blood. He also left some writing around him that could only be seen with a black light. The weirdest thing about this was that he had done all of this to him self.
