 In Sainte-Marguerite, probably because of the valet La Rivière's death, "Dauger" was authorised to go for walks on the Island.However, the fortress of Sainte-Marguerite, unlike that in Exilles, was a real prison where Dauger was likely to meet other prisoners.He was therefore required to wear a mask, to which Marcel Pagnol does not refer during the previous imprisonments in Pignerol then Exilles.
