This is what I was told on the subject. In the spring of 1847 Marguerite was so ill that the doctors ordered her to take the waters, and she went to Bagnères. Among the invalids was the daughter of this duke; she was not only suffering from the same complaint, but she was so like Marguerite in appearance that they might have been taken for sisters; the young duchess was in the last stage of consumption, and a few days after Marguerite’s arrival she died. One morning, the duke, who had remained at Bagnères to be near the soil that had buried a part of his heart, caught sight of Marguerite at a turn of the road. He seemed to see the shadow of his child, and going up to her, he took her hands, embraced and wept over her, and without even asking her who she was, begged her to let him love in her the living image of his dead child. Marguerite, alone at Bagnères with her maid, and not being in any fear of compromising herself, granted the duke’s request. Some people who knew her, happening to be at Bagnères, took upon themselves to explain Mademoiselle Gautier’s true position to the duke. It was a blow to the old man, for the resemblance with his daughter was ended in one direction, but it was too late. She had become a necessity to his heart, his only pretext, his only excuse, for living. He made no reproaches, he had indeed no right to do so, but he asked her if she felt herself capable of changing her mode of life, offering her in return for the sacrifice every compensation that she could desire. She consented. It must be said that Marguerite was just then very ill. The past seemed to her sensitive nature as if it were one of the main causes of her illness, and a sort of superstition led her to hope that God would restore to her both health and beauty in return for her repentance and conversion. By the end of the summer, the waters, sleep, the natural fatigue of long walks, had indeed more or less restored her health. The duke accompanied her to Paris, where he continued to see her as he had done at Bagnères. This liaison, whose motive and origin were quite unknown, caused a great sensation, for the duke, already known for his immense fortune, now became known for his prodigality. All this was set down to the debauchery of a rich old man, and everything was believed except the truth. The father’s sentiment for Marguerite had, in truth, so pure a cause that anything but a communion of hearts would have seemed to him a kind of incest, and he had never spoken to her a word which his daughter might not have heard.
