At the arrest of La Voisin, her maid Margot stated that the arrest would mean the end of a number of people in all levels of society. La Voisin was imprisoned at Vincennes, where she was subjected to questioning. On 27 December 1679, Louis XIV issued an order that the whole network should be exterminated by all methods regardless of the rank, sex, or age. The arrest of La Voisin was followed by the arrest of her daughter Marguerite Monvoisin, Guibourg, Lesage, Bertrand, Romain and the rest of her network of associates.
