Other problems arose in the following years for Liselotte, as she harbored a massive aversion to Madame de Maintenon, the last important mistress and from the end of 1683 the secret wife of Louis XIV, whom she increasingly controlled him. Liselotte couldn't accept the social position and the lust for power of this woman (the widow of a playwright, who rose from difficult circumstances) and described her in numerous letters with epithets like "the King's old drab", "old whore", "old witch", "Megaera", "Pantocrat" or as "mouse filth mixed with the peppercorns". At the instigation of the Maintenon, Liselotte's contacts with her brother-in-law were restricted to formal occasions, and if the King retired to his private apartments with some chosen relatives after dinner, she was no longer admitted. In 1686 she wrote to her aunt Sophia: "Where the devil can't get there, he sends an old woman, whom we all want to find out, being part of the royal family.." and in 1692: "What an executioner We wanted to take our old rumpompel away, should I think he was an honest man and would like to ask him to be ennobled". Since their correspondence was secretly monitored, the King and the Maintenon found out about this and this, of course, had an adverse effect on Liselotte's once good contact with Ludwig.
