So here are Rohan, Cagliostro, and Jeanne all brought acquainted. The Cardinal (and this is one of the oddest features in the affair) was to come to believe that Jeanne was the Queen's most intimate friend, and could and would make his fortune with her; while, at the same time, he was actually relieving her by little tips of from two to five louis! This he was doing, even after, confiding in Jeanne, he handed to her the diamond necklace for the Queen, and, as he believed, had himself a solitary midnight interview with her Majesty. If Jeanne was so great with the Queen as Rohan supposed, how could Jeanne also be in need of small charities? Rohan was a man of the world. His incredible credulity seems a fact so impossible to accept that it was not accepted by public opinion. The Queen, people could not but argue, must have taken his enormous gifts, and then robbed and denounced him. With the case before our eyes of Madame Humbert, who swindled scores of hard-headed financiers by the flimsiest fables, we can no longer deem the credulity of the Cardinal incredible, even though he displayed on occasion a sharpness almost as miraculous as his stupidity.
Rohan conferred a few small favours on Jeanne; her audacity was as great as that of Madame Humbert, and, late in 1781, she established herself both at Paris and in Versailles. The one card in her hand was the blood of the Valois, and for long she could not play it to any purpose. Her claims were too old and musty. If a lady of the name of Stewart were to appear to-day, able to prove that she was of royal blood, as being descended from Francis, Earl of Bothwell (who used to kidnap James VI., was forfeited, and died in exile about 1620), she could not reasonably expect to be peculiarly cherished and comforted by our royal family. Now Jeanne's claims were no better, and no nearer, in 1781, than those of our supposed Stewart adventuress in 1904. But Jeanne was sanguine. Something must be done, by hook or by crook, for the blood of the Valois. She must fasten on her great relations, the royal family. By 1783 Jeanne was pawning her furniture and dining at the expense of her young admirers, or of her servants, for, somehow, they were attached to a mistress who did not pay their wages. She bought goods on her credit as a countess, and sold them on the same day. She fainted in the crowd at Versailles, and Madame Elizabeth sent her a few louis, and had her tiny pension doubled. Jeanne fainted again under the eyes of the Queen, who never noticed her.
Her plan was to persuade small suitors that she could get them what they wanted by her backstairs influence with her royal cousin; she had a lover, Retaux de Villette, who was an expert forger, and by April 1784, relying on his skill, she began to hint to Rohan that she could win for him the Queen's forgiveness. Her Majesty had seen her faint and had been full of kindness. Nothing should be refused to the interesting daughter of the Valois. Letters from the Queen to Jeanne, forged by Villette on paper stamped with blue fleurs de lys, were laid before the eyes of the infatuated prelate. Villette later confessed to his forgeries; all confessed; but as all recanted their confessions, this did not impress the public. The letters proved that the Queen was relenting, as regarded Rohan. Cagliostro confirmed the fact. At a séance in Rohan's house, he introduced a niece of Jeanne's husband, a girl of fifteen, who played the part of crystal gazer, and saw, in the crystal, whatever Cagliostro told her to see. All was favourable to the wishes of Rohan, who was as easy of belief as any spiritualist, being entirely dominated by the Neapolitan. Cagliostro, none the less, knew nothing of the great final coup, despite his clairvoyance.
So far, in the summer of 1784, the great diamond fraud had not risen into Jeanne's consciousness. Her aim was merely to convince the Cardinal that she could win for him the Queen's favour, and then to work upon his gratitude. It was in July 1784 that Jeanne's husband made the acquaintance of Marie Laguay, a pretty and good-humoured but quite 'unfortunate' young woman—'the height of honesty and dissoluteness'—who might be met in the public gardens, chaperoned solely by a nice little boy. Jeanne de Valois was not of a jealous temperament. Mademoiselle Laguay was the friend of her husband, the tawdry Count. For Jeanne that was enough. She invited the young lady to her house, and by her royal fantasy created her Baronne Gay d'Oliva (Valoi, an easy anagram).
She presently assured the Baronne that the Queen desired her collaboration in a practical joke, her Majesty would pay 600l. for the freak. This is the Baronne's own version; her innocence, she averred, readily believed that Marie Antoinette desired her assistance.
'You are only asked to give, some evening, a note and a rose to a great lord, in an alley of the gardens of Versailles. My husband will bring you hither to-morrow evening.'
Jeanne later confessed that the Baronne really was stupid enough to be quite satisfied that the whole affair was a jest.
Judged by their portraits, d'Oliva, who was to personate the Queen, in an interview with the Cardinal, was not at all like Marie Antoinette. Her short, round, buxom face bears no resemblance to the long and noble outlines of the features of the Queen. But both women were fair, and of figures not dissimilar. On August 11, 1784, Jeanne dressed up d'Oliva in the chemise or gaulle, the very simple white blouse which Marie Antoinette wears in the contemporary portrait by Madame Vigée-Lebrun, a portrait exhibited at the Salon of 1783. The ladies, with La Motte, then dined at the best restaurant in Versailles, and went out into the park. The sky was heavy, without moon or starlight, and they walked into the sombre mass of the Grove of Venus, so styled from a statue of the goddess which was never actually placed there. Nothing could be darker than the thicket below the sullen sky.
A shadow of a man appeared: Vous voilà! said the Count, and the shadow departed. It was Villette, the forger of the Queen's letters, the lover and accomplice of Jeanne de Valois.
Then the gravel of a path crackled under the feet of three men. One approached, heavily cloaked. D'Oliva was left alone, a rose fell from her hand, she had a letter in her pocket which she forgot to give to the cloaked man, who knelt, and kissed the skirt of her dress. She murmured something; the cloaked Cardinal heard, or thought he heard, her say: 'You may hope that the past is forgotten.'
