“The machinations against Marie Antoinette could not be concealed from the Empress-mother. An extraordinary Ambassador was consequently sent from Vienna to complain of them to the Court of Versailles, with directions that the remonstrance should be supported and backed by the Comte de Mercy, then Austrian Ambassador at the Court of France. Louis XV. was the only person to whom the communication was news. This old dilettanti of the sex was so much engaged between his seraglio of the Parc-aux-cerfs and Du Barry that he knew less of what was passing in his palace than those at Constantinople. On being informed by the Austrian Ambassador, he sent an Ambassador of his own to Vienna to assure the Empress that he was perfectly satisfied of the innocent conduct of his newly acquired granddaughter.
“Among the intrigues within intrigues of the time I mention, there was one which shows that perhaps Du Barry’s distrust of the constancy of her paramour, and apprehension from the effect on him of the charms of the Dauphine, in whom he became daily more interested, were not utterly without foundation. In this instance even her friend, the Duc de Richelieu, that notorious seducer, by lending himself to the secret purposes of the King, became a traitor to the cause of the King’s favourite, to which he had sworn allegiance, and which he had supported by defaming her whom he now became anxious to make his Queen.
“It has already been said, that the famous Duchesse de Grammont was one of the confidential friends of Louis XV. before he took Du Barry under his especial protection. Of course, there can be no difficulty in conceiving how likely a person she would be, to aid any purpose of the King which should displace the favourite, by whom she herself had been obliged to retire, by ties of a higher order, to which she might prove instrumental.
“Louis XV. actually flattered himself with the hope of obtaining advantages from the Dauphin’s coolness towards the Dauphine. He encouraged it, and even threw many obstacles in the way of the consummation of the marriage. The apartments of the young couple were placed at opposite ends of the palace, so that the Dauphin could not approach that of his Dauphine without a publicity which his bashfulness could not brook.
“Louis XV. now began to act upon his secret passion to supplant his grandson, and make the Dauphine his own Queen, by endeavouring to secure her affections to himself. His attentions were backed by gifts of diamonds, pearls, and other valuables, and it was at this period that Boehmer, the jeweller, first received the order for that famous necklace, which subsequently produced such dreadful consequences, and which was originally meant as a kingly present to the intended Queen, though afterwards destined for Du Barry, had not the King died before the completion of the bargain for it.
