Summary
Analysis
Collet and his agents surround Teabing’s château. Fache calls, irritated that no one updated him on Langdon’s location (although he was on a phone call). Fache insists Collet wait until he arrives to arrest Langdon, ignoring his lieutenant’s protests. Collet assumes Fache wants to make the arrest himself, or else new information has made him doubt Langdon’s guilt. Collet himself can’t understand why Sophie—Saunière’s granddaughter—would assist his murderer. One of Collet’s agents discovers a rental car parked nearby, while another spots the bank’s armored truck inside the fence. Realizing the truck driver (Vernet) from earlier lied, Collet wonders who else is involved in Langdon’s scheme. Meanwhile, the update from Paris has upset Aringarosa. He hopes Fache can fix the situation.
Fache’s frequent phone calls suggest he might be the Teacher, especially when the end of this chapter confirms he called Aringarosa. His insistence that Collet wait to arrest Langdon supports this theory, though it could also simply highlight Fache’s hubris. That Collet also makes note of the captain’s strange behavior and the gaps in his narrative of the crime confirms that, at the very least, Fache knows more about the situation than he’s letting on.
