Héloïse Villefort is the second wife of Villefort and Valentine's stepmother. She is bitter towards her stepdaughter because she knows that Valentine will inherit fortunes from both her maternal grandparents and Noirtier while Madame de Villefort's son Edouard will barely inherit anything from the Villefort estate. Her hobby is gardening in her private greenhouse. She is fascinated by toxicology, and most of the plants she grows are highly poisonous. From her flirtations with the Count and indifference towards her husband, she gives the strong impression that she is a social climber.
