La Voisin denied ever meeting or serving Montespan. She did admit that "Paris is full of this kind of thing and there is an infinite number of people engaged in this evil trade" but refused to mention further clients nor did she mention having arranged or participated in black masses. She once mentioned to the guards that the question she feared most was that they would ask her about her visits to the royal court. It is likely that she was referring to Montespan as her client and her attempt at murdering the King, and that she feared that such a confession should result in her execution for regicide. Her list of clients, the arranging of the black masses, her connection to Montespan and the murder attempt on the King were not revealed until after her death, when it was stated by her daughter and confirmed by the testimonies of her former associates.
