Can this monk be the monk who went mad in prison at Pignerol, sharing the cell of Mattioli? Did he, too, suffer for his connection with the secret? We do not know, but the position of Charles was awkward. Marsilly, dealing with the Swiss, had come straight from England, where he was lie with Charles's minister, Arlington, and with the Dutch and Spanish ambassadors. The King refers to the matter in a letter to his sister of May 24, 1669 (misdated by Miss Cartwright, May 24, 1668.)[1] [1] Madame, by Julia Cartwright, p. 264. "You have, I hope, received full satisfaction by the last post in the matter of Marsillac [Marsilly], for my Ld. Arlington has sent to Mr. Montague [English ambassador at Paris] his history all the time he was here, by which you will see how little credit he had here, and that particularly my Lord Arlington was not in his good graces, because he did not receive that satisfaction, in his negotiation, he expected, and that was only in relation to the Swissers, and so I think I have said enough of this matter." Charles took it easily! On May 15/25 Montague acknowledged Arlington's letter to which Charles refers; he has been approached, as to Marsilly, by the Spanish resident, "but I could not tell how to do anything in the business, never having heard of the man, or that he was employed by my Master [Charles] in any business. I have sent you also a copy of a letter which an Englishman writ to me that I do not know, in behalf of Roux de Marsilly, but that does not come by the post," being too secret.[1] [1] State Papers, France, vol. 126. France had been well-informed about Marsilly while he was in England. He then had a secretary, two lackeys, and a valet de chambre, and was frequently in conference with Arlington and the Spanish ambassador to the English Court. Colbert, the French ambassador in London, had written all this to the French Government, on April 25, before he heard of Marsilly's arrest.[1] [1] Bibl. Nat., Fonds. Francais, No. 10665. The belief that Marsilly was an agent of Charles appears to have been general, and, if accepted by Louis XIV., would interfere with Charles's private negotiations for the Secret Treaty with France. On May 18 Prince d'Aremberg had written on the subject to the Spanish ambassador in Paris. Marsilly, he says, was arrested in Switzerland, on his way to Berne, with a monk who was also seized, and, a curious fact, Marsilly's valet was killed in the struggle. This valet, of course, was not Dauger, whom Marsilly had left in England. Marsilly "doit avoir demande la protection du Roy de la Grande Bretagne en faveur des Religionaires (Huguenots) de France, et passer en Suisse avec quelque commission de sa part." D'Aremberg begs the Spanish ambassador to communicate all this to Montague, the English ambassador at Paris, but Montague probably, like Perwich, knew nothing of the business any more than he knew of Charles's secret dealings with Louis through Madame.[1]
