Question regarding 'first time alone scene' with Cecile and Danceny

Mme. Merteuil had a secret cottage some where that was decorated with what would be condidered porn at the time. You could call it her love shack. I can't remember if it was located somewhere in Paris or if it was actually on her own estate somewhere, but she did keep it a secret and always entered incognito. The woman who dressed Cecile was either a slave or a servant. You can think of her as Marteuil's partner in sexcapades. I think it was standard at that time for a noble to have at least one servant that they kept very close and in confidence to sort of watch their backs. If you remember Valmont had a valet that did some of his dirty deeds for him, and Merteuil asked Cecile if she had a maid she could trust.
