She became the pretended “go-between” between the Cardinal and the Queen, and delivered numerous little notes to him, signed “Antoinette de France.” Finally she arranged an interview for him, at night, in the park of Versailles, ostensibly with the Queen, but in reality with a young girl named d’Oliva who bore a remarkable resemblance to Marie Antoinette. The d’Oliva saw him only for a few moments and presented him with a rose. {66} The Cardinal was completely duped. “Madame de la Motte persuaded him,” says Greeven, “into the belief that the Queen was yearning for the necklace, but, as she could not afford it, he could assure himself of her favor by becoming security for the payment. She produced a forged instrument, which purported to have been executed by the Queen, and upon which he bound himself as security.” The necklace was delivered to the Cardinal, who handed it over to Madame de la Motte, to be given to Marie Antoinette. Thus it was, as Carlyle says, the _collier de la reine_ vanished through “the horn-gate of dreams.” But, asks the curious reader, what has all this to do with Cagliostro? What part had he to play in the drama? This: When the Countess de la Motte was arrested, she attempted to throw the blame of the affair upon the Cardinal and Cagliostro. She alleged that they had summoned her into one of their mystic séances. “After the usual hocus-pocus, the Cardinal made over to her a casket containing the diamonds without their setting and directed her to deliver them to her husband, with instructions to dispose of them at once in London. Upon this information Cagliostro and his wife were arrested. He was detained without hearing, from the 22d of August, 1785, until the 30th of January, 1786, when he was first examined by the Judges, and he was not set at liberty till the 1st of June, 1786.” The trial was the most famous in the annals of the Parliament. Cagliostro and the Cardinal were acquitted with honor. The Countess de la Motte was sentenced to be exposed naked, with a rope around her neck, in front of the Conciergerie, and to be publicly whipped and branded by the hangman with the letter V (_Voleuse—thief_) on each shoulder. She was further sentenced to life imprisonment in the prison for abandoned women. She escaped from the latter place, however, to London, where she was killed on the 23d day of August, 1791, by a fall from a window. The Count de la Motte was sentenced _in contumacium_. He was safe in London at the time and had disposed of the diamonds to various dealers. The d’Oliva was set free without punishment. The man who forged the letter for Madame de la Motte, her secretary, Villette, was banished for life. The Countess de Cagliostro was honorably discharged. {67}
