"Some laundresses wore gloves in those days," said Rossignol, "because their mistresses would have them go into Paris and buy soap that was loaded with arsenic. They would wash the husband’s clothing in that soap, and he would absorb the poison through his skin. And so for a Duchess to make her own soap, on her own estate, is more than just a quaint tradition. It is a way for her to protect herself and those she loves. When she offers you, mademoiselle, the use of her soap, and of her laundry, it means two things: first, that she has true affection for you, and second, that she fears someone might wish you ill."
