How It All Goes Down
- Langdon is obeying Neveu's orders, despite thinking she may be a bit touched in the head.
- They meet in the men's room. Sophie tells him that he's Fache's primary suspect for Saunière's murder, and as such is under strict observation.
- This is confirmed when Langdon finds the GPS tracking dot Collet had snuck into his pocket back in his hotel room.
- Sophie tells him that the reason Fache is so sure that he killed Saunière is because there was a fourth line in his dying message that read: "P.S. Find Robert Langdon."
- Oh. That's a pretty good reason.
