Description
Jeanne Valois, also known as the Countess de la Motte, is a central antagonist in the story, serving as the mastermind behind the infamous Affair of the Diamond Necklace. In the narrative, she is depicted as a beautiful young woman of slender build, possessing long brunette hair and green eyes, with a small birthmark located beneath her left eye. Her appearance is noted to change alongside her fortunes, initially clad in simple red dresses during her impoverished youth and later adorning herself in the expensive gowns and jewelry she believes are her birthright.

Her background is rooted in a deep sense of lost nobility. Jeanne is a descendant of the Valois family, a dynasty that ruled France before the Bourbons. Raised in dire poverty by her mother, Nicole Lamorlière, alongside her younger adoptive sister, Rosalie, Jeanne grew up hating her circumstances. She rejects the life of wearing dirty clothing and eating simple meals, feeling that her noble blood entitles her to a far grander existence. This obsession leads her to abandon her family to pursue her dream of living as a lady.

Driven by an insatiable ambition and a willingness to do anything to escape poverty, Jeanne is a master manipulator. She is a hard-working individual, but her efforts are directed entirely toward social climbing and acquiring wealth. To achieve her goals, she proves herself capable of deceiving, using, and even eliminating those who help her, as well as those who have wronged her. After convincing a noblewoman, the Marquise de Boulainvilliers, to take her in based on her lineage, Jeanne quickly masters the manners of high society. However, gratitude does not temper her greed; she ultimately conspires with her devoted husband, Nicolas de la Motte, to murder her benefactor and forge a will to inherit the fortune.

Her primary motivation evolves from simply wanting a comfortable life to a destructive desire for ultimate power. Dissatisfied with the money she manipulates from a sympathetic Marie Antoinette, Jeanne sets her sights on becoming queen of France. To achieve this, she engineers the Affair of the Diamond Necklace, a complex criminal plot designed to frame the queen and ruin her reputation. When she learns of a priceless diamond necklace originally commissioned for Madame du Barry, she devises a scheme to steal it. Using Cardinal de Rohan's well-known affection for the queen, Jeanne convinces him that she is Marie Antoinette's trusted agent. She orchestrates forged letters, false bribes, and a late-night rendezvous where a prostitute named Nicole d'Oliva, who resembles the queen, impersonates Marie Antoinette.

Jeanne's role in the story is that of a catalyst for disaster, both for the royal family and for those in her personal orbit. While she maintains a complex and deeply possessive love for her husband, Nicolas, she routinely views him as a tool to commit crimes. Similarly, she shows a moment of pity for the prostitute Nicole d'Oliva, unable to bring herself to kill the blind woman to silence her. Her relationship with her sister Rosalie is particularly strained; after achieving wealth, Jeanne cruelly ignores and abandons Rosalie, refusing to acknowledge her past connection.

Throughout the narrative, Jeanne exhibits notable abilities in deception and social engineering. Her talent for manipulation is so profound that she is able to sway public opinion against Marie Antoinette. When finally arrested and put on trial, she refuses to confess until confronted with evidence. Even then, she does not repent. To save herself and further damage the crown, she delivers a final, devastating act of false testimony, publicly claiming that she and the queen were lesbian lovers who conspired together, only to be betrayed by Marie Antoinette. This declaration severely damages the queen's reputation.

In her final development, Jeanne faces the consequences of her actions. Sentenced to be branded as a thief and imprisoned, she manages to escape. However, her end is tragic and intimate. When cornered by the royal guard and facing certain death, she refuses to let her husband, Nicolas, be captured and executed. Demonstrating a twisted form of love and a fear of dying alone, she kills him herself, and the two share a passionate kiss before she ignites gunpowder, ending their lives together in a final embrace. Despite her cruelty to nearly everyone else, her devotion to Nicolas in death reveals a rare, albeit destructive, tender spot within her.
