Jeanne engineered an audacious con: she ingratiated herself with the hapless and ambitious Cardinal Louis de Rohan, who longed for the queen's favor. With spiritual charlatan Count Cagliostro vouching for her and a conspirator—known in accounts as Rétaux de Villette—handling communications and contrivances, Jeanne produced intercepted and forged letters that made the Cardinal believe Marie Antoinette was romantically disposed toward him. To seal the deception she arranged a shadowed rendezvous in the gardens of Versailles where an actress, Nicole Leguay d'Oliva, briefly impersonated the queen. Convinced the sovereign wished the necklace purchased discreetly, the Cardinal bought the jewels and handed them to Rétaux de Villette; portions were then sold by Jeanne's husband to finance her restoration to the family home. The scheme collapsed when Minister de Breteuil uncovered the jeweler Benjamin Böhmer's anxious trip to the Cardinal and alerted the king—Louis XVI had the Cardinal arrested and thrown into the Bastille. A highly public trial followed: the Cardinal, Cagliostro and Leguay were sensationally acquitted, Rétaux de Villette was convicted and banished, and Jeanne was found guilty, whipped, branded and imprisoned before escaping to London to publish her memoirs. Rumors dogged her death abroad—she 'fell from a hotel window' and was whispered to have been finished off by Royalists—and the whole affair poisoned the public view of the queen, feeding the swirl of indignation that would soon consume the Ancien Régime. The Necklace Affair remains one of the late-18th century's most theatrical scandals: forgery, impersonation, clerical humiliation, public trial and the branding of an ambitious woman—events that combined to discredit the monarchy on the eve of revolution.
