Guillaume DUBOIS (1656-1723) cardinal, diplomat and minister. L.S., Briançon October 17, 1706; 4pages in-4. "His Royal Highness [...] was charmed by your relation and said the most pleasant things in the world about what you have done". He congratulates his correspondent on having accomplished this mission so honorably: "the more difficult they are, the better you aquit yourself"... On the other hand, the Duc d'Orléans asks him to pay particular attention to the news and "spare neither care nor money to be informed of everything that concerns Asti, without making too much noise"... He speaks of several details to be settled, and warns that "His Royal Highness believes that we must always keep in prison the partisan who says he wants to withdraw to Morienne, because we will find some proof that he is a spy, or if he is not, he will not harm us in the meantime"...
