Catherine Monvoisin was the wife of a jeweller and silk merchant. She had a comfortable home in the fashionable Villeneuve Sur Gravois neighbourhood in the centre of Paris. She was a mother, an entrepreneur, a philanthropist, and a lover of the arts. But she was also a witch, one who nearly overthrew the French aristocracy and almost succeeded in slaying a king.
