Since I did myself the honour of writing to you, I have taken down shortly in writing all the information I have been able to draw from the Sieur de Lestang. By making him perceive, and roughly too, the misery to which his bad conduct exposed him, I induced him to seek for the means of avoiding it, by doing readily and frankly all that was desired of him. I have not said any thing to him which could make him discover the means by which we have been so certainly informed of his treachery; but I have spoken to him in such a manner on that subject, that he cannot doubt that we know it, and are convinced of it. He is a rascal; but I believe him to be honest in his desire of delivering up the papers, either from the fear which his present condition causes him, or with the view of rendering a service to the King, which may be agreeable to him, and may make him forget what is past. The original papers are at Padua, concealed in a hole in the wall of a room, which is in his father’s lodging, and which he says is known to him alone. These papers are the treaty made by M. de Pomponne, signed by him and by Matthioli, signed below by the Duke of Mantua, a blank being left for the insertion of the ratification, when the exchange should be made for that of the King; a blank paper signed by the Duke of Mantua, intended for a letter to the Governor of Casale, to order him to receive the troops of the King; the full power given to M. de Pomponne to treat with him respecting Casale; and a list of the troops destined to the execution of this affair. If we once have possession of these papers, the affair is concluded as far as regards negociation; but this is a fact that we need only make known when we think proper. As I am aware of what importance it is to have possession of these original papers, I have acquainted the Abbé d’Estrades with the expedients I thought might be made use of for this purpose, in order that I may be assisted by his advice. I do not detail them at present to you, Sir, because I expect to-day the Sieur Giuliani, whom the Abbé d’Estrades is to send to me, together with the Abbé de Montesquiou, his relation, for the purpose of the former’s being confronted with the Sieur de Lestang. As this interview will probably suggest to me more certain means of getting possession of these papers, I will not, as yet, acquaint you, Sir, with those that I had proposed to myself. There are, besides, other papers at Bologna, which are only letters and papers we have, as it seems to me, little need of; knowing, as we do, by the list of those which are at Padua, that it is these alone which particularly regard the affair in question. I will do myself the honour to send you word, Sir, by the next post, what shall have been the issue of the interview between the Sieur de Lestang and Giuliani.
