Also known as La Voisin (the neighbor), Catherine Monvoisin was the wife of a French jeweler, and became famous thanks to the premonitions she's had ever since she was little. After her husband's business went bankrupt, she extended her field of expertise from palm reading to selling love potions, poisons,
and even abortion drugs. Among her clients were many noblemen, countesses, and princesses. She was arrested, together with her daughter, under the accusation of witchcraft, and was burned at the stake in 1680 at Place de Grieve, near Paris. After her death, her daughter's declarations revealed a series of secrets at the high court, including a plot to poison the king.
