Margarette is on of the workers at the Swiss Embassy of France during 1902. Her job is to watch over Elsa and make sure she doesn't go out at night. Elsa and Margarette have a special bond so she let's Elsa sneak out of the embassy without her father knowing. When Sutekh's mummies attack the embassy it is not clear if Margarette was on duty and killed by them, but since she was not seen it is assumed that she was not working during that hour.
