Dominique Guillaume Lebel (1696–1768) or also Le Bel, had the important court role of Premier valet de chambre for King Louis XV of France.
The tactic for this was to invite the young woman to a supper in a dining room in the palace of Versailles, and the monarch could examine her through a hole in the wall next door.
As soon as Richelieu and Lebel spoke of the king's need for a new mistress to save him from his depression, the count pounced on the opportunity.
When Lebel's conscience could take no more, he divulged all about Jeanne to the king, who scolded him harshly to have her married off to gain a title in order for her to become next royal mistress.
During her time in Versailles awaiting a date for her official presentation, Jeanne was given Lebel's quarters as living space.
