She remained duly respectful towards her patroness until her Valois ancestry was formally recognised in 1776 and the King granted her a civil-list pension of 800 livres. Then she summoned her one surviving younger sister, Marie-Anne, and together they entered the convent at Longchamps, where only the daughters of the aristocracy were admitted as pupils.

Jeanne was twenty-one, and her restlessness was steadily increasing. No matter what happened, she could not erase the memory of her childhood: she would always be the Valois heir who had begged in the dust of the highway; the déclassée: an enemy of the entire social order.

“My indomitable pride I was given by nature,” she wrote, “and Mme de Boulainvilliers’s charity simply exacerbated it. Oh God, why was I born of Valois blood? Fatal name, you exposed my soul to savage pride! You are the cause of these tears; it is because of you that I am so unhappy.”

This sort of person always possesses a certain insinuating eloquence: especially when they are parading their sorrows.

She did not remain long in the convent. She felt not the slightest calling to become a nun, and one fine day she and her sister made their escape. The word went round Bar-sur-Aube that two duchesses had come to recover their ancestral lands and had taken rooms at the very cheapest hotel. A Mme Surmont, wife of the Master of the Law Court and the lynchpin of local society, decided it was her duty to take them—two young ladies in distress, no doubt pursued by mysterious enemies—into her home. Since both were clad in the meanest of attire, she immediately lent each of them one of her own dresses, much to the amusement of the young people present, since the good lady was extremely large. By the next day they had been completely retailored to make a perfect fit. The Master’s wife was somewhat taken aback, but she slowly became used to the fact that Jeanne was now mistress of the house. The two girls came for a week and stayed for a year. That year, the lady said later, was the most painful of her entire life.

It was here that Jeanne met Marc-Antoine-Nicolas de la Motte. He was a young nobleman, an officer with the gendarme regiment stationed at nearby Lunéville, where his father, a Knight of the Order of St Louis, had also once served. The local aristocracy in Bar were keen on amateur dramatics, as was the whole world at that time. La Motte was considered a great theatrical talent, and there can be no doubt that Jeanne really was one. They were often in the same play. “They recited and rehearsed together,” comments Funck-Brentano, in his benevolent elderly manner, “to the point where it became urgently necessary to marry.” They were united on 6th June 1780.

The Master’s wife finally took the opportunity to throw Jeanne out, and after a period of wandering the young couple settled in Lunéville. Twins were born, but they died soon after, and it seems that, for reasons of economy, Jeanne returned for a while to the convent. Otherwise the couple lived on credit and from La Motte’s shady dealings. At around this time he began to call himself Comte.

There is nothing particularly to be said about this gentleman, and no need to describe him in detail. He was one of those suave and thoroughly loathsome characters, those shameless and craven pimps that everyone who goes to France has met by the thousand—a type long established in that country, it seems. He hated work, loved women, was extremely ugly, but thought himself so extraordinarily handsome that every so often some woman or other actually believed him.

In September 1781 the young couple learnt that Jeanne’s patroness the Marquise de Boulainvilliers was staying at Saverne Castle as the guest of Cardinal Rohan. The mysterious inner voice that directed all Jeanne’s talents spoke again—they packed up and removed to Saverne.

Jeanne was now twenty-five. Her hair was naturally curled and chestnut brown, her eyes blue and expressive, her mouth equally so, if a little on the large side. Her smile was enchanting. As Beugnot, speaking from experience, put it, it “spoke to the heart”. Her bosom was considered by contemporaries to be rather underdeveloped. Her main attractions, it seems, were her voice and her conversation. “Nature gave her the dangerous gift of eloquence,” said one of the leading actors in the necklace trial, who added: “—eminently suitable for discussing those matters of civil law and ethics of whose existence Mme de la Motte, in all her innocence and eternal naturalness, had not the slightest suspicion.”

The Grand Seigneur

THE GREAT HISTORIANS OF ANTIQUITY, in particular Livy, would always introduce their account of some major event by detailing the signs and auguries that foretold it. This was partly a religious requirement, since they did after all believe in these things, but it was also, it seems, a device to elevate the tone of the writing.
