Sophie Neveu's Intervention

Sophie Neveu, a cryptologist from the DCPJ, interrupts Fache and Langdon. She claims to have deciphered the numeric code as the Fibonacci sequence. She also tells Langdon he has an urgent message from the U.S. Embassy. Using Fache's phone, Langdon calls a number she gives him, but instead of the embassy, he reaches Sophie's personal voicemail. Her message warns him that he is in danger and that Fache suspects him of the murder. She instructs him to follow her directions.
