What form these took seems clear from an investigation held at the close of 1678 into a supposed plot to poison the King and the Dauphin--a plot of which La Voisin, one of the greatest criminals in history, was suspected of being the ringleader. During this inquiry La Voisin confessed that the Comtesse de Soissons had come to her house one day "and demanded the means of getting rid of Mile de la Vallière"; and, further, that the Comtesse had avowed her intention to destroy not only Louis' mistress, but the King himself. Such a confession was well calculated to rouse a storm of indignation in France, where Madame de Soissons had made many powerful enemies. The Chambre unanimously demanded her arrest; but before it could be effected, Madame, stoutly declaring her innocence, had shaken the dust of Paris off her feet, and was on her way to Brussels. During her flight to safety, we are told, "the principal inns in the towns and villages through which she passed refused to receive her"; and more than once she was compelled to sleep on straw and suffer the insults of the populace, which reviled her as sorceress and poisoner. "We are assured," Madame de Sevigné writes, "that the gates of Namur, Antwerp, and other towns have been closed against the Countess, the people crying out, 'We want no poisoner here'!" Even at Brussels, whenever she ventured into the streets she was assailed by a storm of insults; and on one occasion, when she entered a church, "a number of people rushed out, collected all the black cats they could find, tied their tails together, and brought them howling and spitting into the porch, crying out that they were devils who were following the Comtesse." In the face of such chilling hospitality Madame de Soissons was not tempted to make a long stay in Brussels; and after a few months of restless wandering in Flanders and Germany, she drifted to Spain where she succeeded in ingratiating herself with the Queen. She found little welcome however from the King, who, as the French Ambassador to Madrid wrote, "was warned against her. He accused her of sorcery, and I learn that, some days ago, he conceived the idea that, had it not been for a spell she had cast over him, he would have had children.... The life of the Comtesse de Soissons consists in receiving at her house all persons who desire to come there, from four o'clock in the evening up to two or three hours after midnight. There is, sire, everything that can convey an air of familiarity and contempt for the house of a woman of quality."
