The Abbot confirms that François did not usually leave the abbey, only to do his chores and that he was going to confirm vows in two weeks together with the other novice, Benoît. During the investigation, it is revealed that the strange mark on the victim's hand is related to the last tear of Saint Louis legend and a treasure of the Crusaders.
