When she judged that the moment for action had arrived, Madame de Prie communicated with Dubois, who, armed with the reports she had sent him, went to the Regent, laid them before him, and told him very plainly that he could no longer support Le Blanc without being immediately compromised. Philippe d’Orléans, after a perusal of the documents, was obliged to acknowledge that the Minister was right, and authorized him to take what steps he considered advisable in the matter. Dubois lost no time in setting the Law in motion; the commission met at the house of the Maréchal de Villars, who had been appointed president; and on 24 May La Jonchère was arrested as he was returning from Versailles, in virtue of a _lettre de cachet_ signed by the Cardinal, and conducted to the Bastille, while the seals were placed on his hôtel in the Rue Saint-Honoré, and all his registers and papers seized by the police. At the Bastille, La Jonchère was subjected to two long interrogatories by Ravot d’Ombreval, a relative of Dubois, who acted as attorney-general to the commission. He appeared very agitated, contradicted himself several times, and ended by admitting that he had acted dishonestly, and that he was not the only one guilty, though he obstinately refused to give the names of his accomplices. A few days later, two of La Jonchère’s principal clerks were also arrested, and on 18 June the treasurer was conducted to his house to be present at the raising of the seals and the sorting of his papers. This operation lasted from eleven o’clock in the morning until nine in the evening, when he was escorted back to the Bastille, guarded by forty archers and followed by two carts filled with his registers and papers. The examination of these, which was carried out under the supervision of the Lieutenant of Police, d’Argenson, revealed immense defalcations, and, moreover, left no room for doubt as to the culpability of Le Blanc. It also showed that La Jonchère had received a great number of the discredited notes of Law’s Bank, for which he had presumably given in exchange gold to the amount of their face value.
