At the time when she came thus dramatically into his life she was living with Madame de Mazarin, a strong-minded woman who had no cause to love Louis, who had thwarted and opposed him more than once, and who was determined at any cost to keep her protégée and pet out of his clutches. And his desires had also two other stout opponents in Cardinal Fleury, his old mentor, and Maurepas, the most subtle and clever of his ministers, each of whom for different reasons was strongly averse to this new and dangerous liaison, which would make him the tool of Richelieu's favourite and Richelieu's party.

Thus, for months, Louis found himself baffled in all his efforts to win the prize on which he had set his heart until, in September, 1742, one formidable obstacle was removed from his path by the death of Madame de Mazarin. To Madame de la Tournelle the loss of her protectress was little short of a calamity, for it left her not only homeless, but practically penniless; and, in her extremity, she naturally turned hopeful eyes to the King, of whose passion she was well aware. At least, she hoped, he might give her some position at his Court which would rescue her from poverty. When she begged Maurepas, Madame de Mazarin's kinsman and heir, to appeal to the King on her behalf, his answer was to order her and her sister, Madame de Flavacourt, to leave the Hotel Mazarin, thus making her plight still more desperate.

But, fortunately, in this hour of her greatest need she found an unexpected friend in Louis' ill-used Queen, who, ignorant of her husband's infatuation for the beautiful Madame de la Tournelle, sent for her, spoke gracious words of sympathy to her, and announced her intention of installing her in Madame de Mazarin's place as a lady of the palace. Thus did fortune smile on Madame just when her future seemed darkest. But her troubles were by no means at an end. Fleury and Maurepas were more determined than ever that the King should not come into the power of a woman so alluring and so dangerous; and they exhausted every expedient to put obstacles in her path and to discover and support rival claimants to the post.

For once, however, Louis was adamant. He had not waited so long and feverishly for his prize to be baulked when it seemed almost in his grasp. Madame de la Tournelle should have her place at his Court, and it would not be his fault if she did not soon fill one more exalted and intimate. Thus it was that when Fleury submitted to him the list of applicants, with la Tournelle's name at the bottom, he promptly re-wrote it at the head of the list, and handed it back to the Cardinal with the words, "The Queen is decided, and wishes to give her the place."

We can picture Madame de Mailly's distress and suspense while these negotiations were proceeding. She had, as we have seen in the previous chapter, been supplanted by one sister in the King's affection; and just as she was recovering some of her old position in his favour, she was threatened with a second dethronement by another sister. In her alarm she flew to Madame de la Tournelle, to set her fears at rest one way or the other. "Can it be possible that you are going to take my place?" she asked, the tears streaming down her cheeks. "Quite impossible, my sister," answered Madame, with a smile; and Madame de Mailly, thus reassured, returned to Versailles the happiest woman in France—to learn, a few days later, that it was not only possible, it was an accomplished fact. For the second time, and now, as she knew well, finally, she was ousted from the affection of the King she loved so sincerely; and again it was a sister who had done her this grievous wrong. She was determined, however, that she would not quit the field without a last fight, and she knew she had doughty champions in Fleury and Maurepas, who still refused to acknowledge defeat.

Although Madame de la Tournelle was now installed in the palace, the day of Louis' conquest had not arrived. The gratification of his passion was still thwarted in several directions. Not only was Madame de Mailly's presence a difficulty and a reproach to him; his new favourite was by no means willing to respond to his advances. Her heart was still engaged to the Due d'Agenois, and was not hers to dispose of. Richelieu, however, was quick to dispose of this difficulty. He sent the handsome Duc to Languedoc, exposed him to the attractions of a pretty woman, and before many weeks had passed, was able to show Madame de la Tournelle passionate letters addressed to her rival by her lover, as evidence of the worthlessness of his vows; thus arming her pride against him and disposing her at last to lend a more favourable ear to the King.

As for Madame de Mailly, her shrift was short. In spite of her tears, her pleadings, her caresses, Louis made no concealment of his intention to be rid of her. "No sorrow, no humiliation was lacking in the death-struggle of love. The King spared her nothing. He did not even spare her those harsh words which snap the bonds of the most vulgar liaisons." And the climax came when he told the heart-broken woman, as she cringed pitifully at his feet, "You must go away this very day." "My sacrifices are finished," she sobbed, a little later to the "Judas," Richelieu, when, with friendly words, he urged her to humour the King and go away at least for a time; "it will be my death, but I will be in Paris to-night."

And while Madame de Mailly was carrying her crushed heart through the darkness to her exile, the King and Richelieu, disguised in large perukes and black coats, were stealing across the great courtyards to the rooms of Madame de la Tournelle, where the King's long waiting was to have its reward. And, the following day, the usurper was callously writing to a friend, "Doubtless Meuse will have informed you of the trouble I had in ousting Madame de Mailly; at last I obtained a mandate to the effect that she was not to return until she was sent for."

"No portrait," says de Goncourt, referring to this letter, "is to be compared with such a confession. It is the woman herself with the cynicism of her hardness, her shameless and cold-blooded ingratitude.... It is as though she drives her sister out by the two shoulders with those words which have the coarse energy of the lower orders."

Louis, at last happy in the achievement of his desire, was not long in discovering that in the third of the Nesle sisters he had his hands more full than with either of her predecessors. Madame de Mailly and the Comtesse de Vintimille had been content to play the rôle of mistress, and to receive the King's none too lavish largesse with gratitude. Madame de la Tournelle was not so complaisant, so easily satisfied. She intended—and she lost no time in making the King aware of her intention—to have her position recognised by the world at large, to reign as Montespan had reigned, to have the Treasury placed at her disposal, and her children, if she had any, made legitimate. Her last stipulation was that she should be made a Duchess before the end of the year. And to all these proposals Louis gave a meek assent.
