I HAVE delivered to the Abbé d’Estrades, by the hands of his relation, the Abbé de Montesquiou, all the letters and papers of the Sieur de Lestang, which consisted in many letters, of which I have kept a list, containing shortly the subject of each letter. These letters only show his journeys backwards and forwards; there are some of them in which he is advised to take care of himself; one, among others, is from the Ministers of Mantua, informing him of the joy of the Duke at his prosperous return from France, and of his having sent a boat to Placentia for him, in order that he may come to him more securely and more conveniently. He had many other papers, among which I have seen nothing of consequence, except a Spanish cypher, which he confesses to have come from the Count de Melgar.[279] I made him relate before me to the Abbé de Montesquiou, all that he had done since his return from France, without interrupting him; having, nevertheless, let him know, before I permitted him to speak, that we were perfectly well-informed of his villainy, in order to see what colour he would give to his bad conduct. He says, that on his return from France, he went to Turin, where, from gratitude to that court, which had done him the honour of making use of him in many affairs, he thought himself obliged, on account of civility, to see the President Turki;[280] that it was true, in talking of news and of the state of affairs at present, he allowed him to discover that something new was about to take place in Italy; and that the aforesaid President, in the course of the conversation he had with him, gave him to understand that he had no doubt there had been a treaty made respecting Casale. It is thus that the Sieur de Lestang relates what he did at Turin, in order to excuse his treachery there, of which you, Sir, are already perfectly well-informed, as well as of the money he received for it. This was the first discovery that had been made of this affair, which hitherto had been conducted so secretly.
