Set in seventeenth-century France, THE MARQUISE OF DARKNESS is based on the real-life exploits and crimes of poisoner Marie-Madeleine d’Aubray, Marquise de Brinvilliers.

As Madeleine’s husband wastes their money on gambling, she turns to her lover Godin de Sainte-Croix the poison maker. With his help, Madeleine poisons a family member to gain an inheritance. When her husband squanders this fortune at the card table, Madeleine commits further atrocities for financial gain.

This petite and pretty aristocrat is really a cold-blooded killer. Aided by Sainte-Croix and cunning servant La Chaussée, Madeleine stops at nothing to get what she wants, be it via seduction, poisoning, or arson. As her ambitions grow, Madeleine takes greater risks. Could this lead to self-destruction, or will Darkness prevail?

Note: contains graphic scenes of torture and violence, plus scenes of a sexual nature.
