Vernet puts Sophie and Langdon in the back of an armored truck, changes into a driver’s uniform, and hides a gun under his clothes. As he drives them away from the bank, Officer Collet stops him and interrogates him. Vernet pretends to be a blue-collar driver and says he does not have the keys to the trunk. Collet sees Vernet’s Rolex and grows suspicious, but ultimately he lets Vernet go. Langdon realizes that they must be holding the Priory keystone. He says that only the leader of the Priory would have access to the keystone, and Sophie says she thinks her grandfather may have been the leader of the Priory. The car stops and Vernet lets them out, but then apologetically pulls a pistol on them.Vernet tells Langdon and Sophie to give him the box. He just heard over the radio that they are wanted for three other murders. Langdon realizes who the three must have been. He hands the box over to Vernet, but he also manages to put a spent shotgun shell into the mechanism of the door. When Vernet tries to shut them into the truck, the door balks. Langdon bursts out of the door, takes the box back, and gets back into the truck while Sophie drives away.
