Description
Jeanne Valois de la Motte is a central antagonist in the story, a character whose desperate ambition and cunning nature set in motion one of the most damaging scandals to plague the royal court. She is introduced as a beautiful young woman with a slender figure, long brunette hair, and green eyes, marked by a small birthmark beneath her left eye. Her appearance, however, belies her humble and impoverished origins.

Born into a family that was once part of the esteemed Valois dynasty, Jeanne is acutely aware of her noble lineage but has only ever known a life of poverty. She grows up in destitution, eating simple meals and wearing dirty clothing, a situation she deeply resents. This resentment festers into an unyielding obsession with reclaiming what she believes is her birthright: a life of wealth, status, and power as a noble lady. Her personality is defined by this relentless drive. She is exceptionally hardworking when it serves her goals, quickly mastering the etiquette and manners required to navigate high society. However, her ambition is coupled with a profound ruthlessness. Jeanne is willing to deceive, manipulate, and even kill anyone who stands in her way, from those who show her kindness to those she claims to love.

Her primary motivation is survival and social ascent, but this evolves into a far grander and more dangerous desire. Having tasted a better life, she becomes insatiable, eventually dreaming of becoming the queen of France herself. To achieve this, she orchestrates the infamous Affair of the Diamond Necklace, a complex fraud designed to enrich herself and simultaneously ruin the reputation of Queen Marie Antoinette.

Jeanne plays a pivotal role in the narrative as the mastermind behind the necklace affair. She begins by securing a patron, the Marquise de Boulainvilliers, by claiming her Valois heritage. Once she has learned the ways of the nobility, she has her husband, Nicolas de la Motte, murder the Marquise so they can forge a will and inherit her fortune. Still unsatisfied, she learns of a magnificent diamond necklace commissioned for Louis XV and sees an opportunity. Using her charm and manipulation, she exploits the desperate infatuation of Cardinal de Rohan, who wishes to regain the queen's favor. Jeanne fabricates letters from Marie Antoinette and even hires a woman, Nicole d'Oliva, to impersonate the queen at a nighttime meeting in the gardens of Versailles, convincing the Cardinal to purchase the necklace for the queen on her behalf. Jeanne then takes the necklace and sells the jewels on the black market.

Her relationships are primarily transactional, serving her ambition. Her younger adoptive sister, Rosalie Lamorlière, is someone Jeanne cared for in their difficult childhood, but once Jeanne achieves wealth, she coldly distances herself and pretends not to know her. Her husband, Nicolas de la Motte, is her most loyal accomplice. She uses him to commit her most heinous crimes, yet a complicated, genuine affection exists between them. He is devoted to her completely, and in her final moments, Jeanne shows a rare tenderness by killing him herself to spare him from a life in prison without her, sharing a passionate final kiss before their deaths.

Jeanne undergoes a clear but tragically consistent development. She transforms from a desperate, impoverished girl into a confident, cunning criminal mastermind. When caught and put on trial, she does not repent. Instead, she desperately tries to save herself by leveling false accusations, claiming she was Queen Marie Antoinette's lesbian lover and that they conspired together, a lie that devastates the queen's public image and fuels revolutionary sentiment. Though she is branded with a hot iron as a thief and imprisoned, she orchestrates an escape. Ultimately cornered, she chooses to end her life in an explosion, taking her husband with her rather than face capture.

Her notable abilities are her sharp intellect, her masterful skill in deception, and her extraordinary charisma. She can read people's desires and weaknesses, as seen in her manipulation of the lovesick Cardinal de Rohan. She is also highly adaptable, capable of assuming the identity and manners of a noblewoman perfectly despite her lowly upbringing. This combination of brains and ruthless ambition makes her one of the most formidable and destructive figures in the story.
