Analysis
Fache is annoyed that Sophie isn’t answering his calls. He tells Collet the Cryptology director called to say his team hasn’t found any references for Saunière’s “Draconian devil” or “lame saint,” but the numbers are from the Fibonacci sequence. Collet is confused: Sophie already told them about the numbers. Fache claims the director never sent Sophie, who left the office immediately after seeing the crime scene photos. Neither Fache nor Collet knew that Saunière was Sophie’s grandfather. Privately, Collet wonders if Saunière left the meaningless numbers to involve his granddaughter. Suddenly, an alarm sounds from the Grand Gallery. Langdon has broken the bathroom window. Fache runs out while Collet watches as Langdon’s dot jumps out the window and onto the pavement.
The Cryptology director’s call exposes Sophie’s manufactured reasons for coming to the crime scene. According to Sophie herself, Collet’s theory that Saunière was trying to involve Sophie in his murder investigation is likely correct, highlighting his detective acumen. That said, Collet doesn’t share his suspicions with Fache, suggesting he is wary of the hierarchical pecking order. Their speculations are cut short by Langdon’s apparent escape attempt.
