Career
She was one of the key figures in the famous Poison Affair. In late 1678, Vigoreaux hosted the party were Maitre Perrin heard Marie Bosse say that she was a professional poisoner. This led to the arrest of Vigoreaux and Bosse as well as Bosse"s family on 4 January 1679.
They were the first to be arrested in the actual Poison Affair, and their testimony led to the arrest of Louisiana Voisin and the exposure of her whole organisation.
Marie Vigoreaux was proven to be closely linked to the Bosse family, as she was claimed to have had sexual relations with all of the family members. At the threat of torture, Vigoreaux and Bosse confessed to be poisoners and made a list of their customers and colleagues.
Vigoreaux implicated Marguerite de Poulaillon by naming her as her client: when Poulaillon expressed that she wished to be a widow, Vigoreaux had recommended her to Bosse. Vigoreaux had also been commissioned by the Marquis de Feuquieres to make him untouchable in battle by the use of magic, and to murder someone who tried to prevent him from marrying.
4 May 1679, Vigoreaux and Bosse was sentenced to be tortured and burned to death.
Marie Vigoreaux died during torture in a device designed to crush bones. Marie Vigoreaux is portrayed in a novel by Judith Merkle Riley: The Oracle Glass (1994).
