 Giles de Rais (Vincent Cassel (qv)s character) was a real person  who after the war and Joans death retired to his lands. Years  later, he was arrested for the murder of more than a hundred young  boys and was executed. Some historians believe that his crimes  became the basis for the French fairy tale "Bluebeard" about a rich  man who murders his wives and hides their bodies in his grand house.
