Escape from the Louvre

Sophie devises a plan to escape. She embeds the GPS tracking dot in a bar of soap and throws it out the bathroom window onto a passing truck, tricking Fache into thinking Langdon has jumped. While Fache and his men chase the truck, Sophie and Langdon hide in the Grand Gallery. They then use an emergency stairwell to leave the museum, successfully evading the police. Langdon is now a fugitive, forced to trust Sophie.
