It was said that in her prison of Château Gaillard she had suffered violence from her jailer; it is more charitable to suppose that this is so than to assume, as some do, that she was so depraved in morals as voluntarily to abandon herself to debauchery; and one must always remember that it was to the interest of the court party to represent her in colors as dark as possible. The belief in her guilt, nevertheless, cannot be avoided; and even her mother gives silent proof of her belief in it, for after the disgrace of her daughter, that daughter's name appears no more in the accounts of Mahaut's household. Blanche retired to the convent of Maubuisson, where she took the veil in 1325, and died in the next year. Under "a large white stone, much carved and decorated with roses, without any inscription, and bearing a figure representing a nun," lay the body of the unhappy Blanche, once Queen of France in right. Her companion in debauchery, Marguerite de Bourgogne, met a fate more suddenly tragic, though surely not more pathetic. Her marriage with Louis le Hutin could have been dissolved, of course, on the score of adultery; but Louis preferred less public methods. Having become king, on the death of his father, not many months after Marguerite's disgrace, he desired to find another wife; so Marguerite was put to death in the Château Gaillard, being smothered, it is said, between two mattresses. The third of the daughters-in-law of Philippe le Bel, the Countess Jeanne de Poitiers, was more fortunate than her sister and Marguerite. When the three had been arrested she was separated from the other two and sent to Dourdan. Her character seems to have been better formed than that of Blanche, and she had not indulged in the excesses proved against Blanche and Marguerite. Mahaut was from the first firmly convinced of her innocence, and sent frequent messages of consolation and sympathy to her during her confinement in Dourdan. Although she had been aware of the evil practices of her sister and her sister-in-law, it could hardly be held an unpardonable crime for her to have refrained from talebearing. In one of the rhymed chronicles, which gives a graphic account of this tragedy, Jeanne is represented as confessing her small share in the wrong and pleading for mercy before Philippe le Bel: "Sire, for God's sake hear me! Who is it that accuses me? I say I am a good woman, without guilt, without sin or shame." She demanded an investigation, and the king granted her request. While she was confined a strict inquiry was held into her conduct, and the result was that, at Christmastide, 1314, she was adjudged innocent, and came back to her husband, "whereof there was great joy throughout France." She was to become Queen of France not long afterward, and then to be widowed; but during the rest of her life there was no blot on her good name, and no interruption in the affectionate relations existing between herself and her mother.
