Cardinal Mazarin, after his return to Paris, made it his chief study to divide the Fronde. He thought to materially weaken my interest with Monsieur by detaching from me Madame de Chevreuse, for whom he had a natural tenderness, and to give me a mortal blow by embroiling me with Mademoiselle her daughter. To do this effectually he found a rival, who, he hoped, would please her better, namely, M. d'Aumale, handsome as Apollo, and one who was very likely to suit the temper of Mademoiselle de Chevreuse. He had entirely devoted himself to the Cardinal's interest, looked upon himself as very much honoured by this commission, and haunted the Palace of Chevreuse so diligently that I did not doubt but that he was sent thither to act the second part of the comedy which had miscarried so shamefully in the hands of M. de Candale. I watched all his movements, and complained to Mademoiselle de Chevreuse, but she gave me indirect answers. I began to be out of humour, and was soon appeased. I grew peevish again; and Mademoiselle de Chevreuse saying in his presence, to please me and to sting him, that she could not imagine how it was possible to bear a silly fellow, "Pardon me, mademoiselle," replied I, "we suffer fops sometimes very patiently for the sake of their extravagances." This man was notoriously foppish and extravagant. My answer pleased, and we soon got rid of him at the Palace of Chevreuse. But he thought to have despatched me, for he hired one Grandmaison, a ruffian, to assassinate me, who apprised me of his design. The first time I met M. d'Aumale, which was at the Duc d'Orleans's house, I did not fail to let him know it; but I told it him in a whisper, saying that I had too much respect for the House of Savoy to publish it to the world. He denied the fact, but in such a manner as to make it more evident, because he conjured me to keep it secret. I gave him my word, and I kept it. Madame de Guemenee, with whom I had several quarrels, proposed to the Queen likewise to despatch me, by shutting me up in a greenhouse in her garden, which she might easily have done, because I often went to her alone by night; but the Cardinal, fearing that the people would have suspected him as the author of my sudden disappearance, would not enter into the project, so it was dropped. To return to our negotiations for the freedom of the Princes. The Duc d'Orleans was with much difficulty induced to sign the treaty by which a marriage was stipulated between Mademoiselle de Chevreuse and the Prince de Conti, and to promise not to oppose my promotion to the dignity of a cardinal. The Princes were as active in the whole course of these negotiations as if they had been at liberty. We wrote to them, and they to us, and a regular correspondence between Paris and Lyons was never better established than ours. Bar, their warder, was a very shallow fellow; besides, men of sense are sometimes outwitted.
