Summary: The GPS marker begins moving again. Collet directs Fache via walkie-talkie to follow Langdon. But while Fache believes he is cornering Langdon beneath a tarp on the back of a truck onto which Langdon must have jumped, Langdon and Neveu are actually still inside the Louvre. Sophie had broken the window and tossed the GPS marker (embedded in bar of soap) onto the truck as it passed below.
Analysis: The action picks up speed as Sophie hatches a plan to lead Fache on a merry chase. Langdon thinks to himself, “Sophie Neveu was clearly a hell of a lot smarter than he was,” which continues Sophie’s character development (see Chapter 16) and also subtly and quite appropriately plays on her name. As the novel will make explicit later, Sophie is a diminutive form of “Sophia,” which in Greek means “wisdom.” This chapter shows us her practical wisdom in action.
