Affair of the Diamond Necklace
At this time, the Cardinal was trying to get the Queen's to like him again so that he could become Prime Minister of France. Jeanne de la Motte persuaded Rohan that she had been friends with the Queen. After hearing this, Rohan used Jeanne to get the Queen to like him again (though he did not know that Jeanne was lying to him). Jeanne promised the Cardinal that she will get the Queen to like him.
