Pinchesne was, at this time, convinced of the perfidy of Matthioli, having, in addition to various other suspicious circumstances, discovered that he had been secretly at Milan for some days. He, however, did not think it advisable entirely to break with him; but advised him to go and confer with Estrades, at Turin; representing to him the danger to which he exposed himself if this affair failed of success through his fault.[69] Matthioli followed the advice of Pinchesne to his own ruin, and going to Turin, presented himself forthwith to Estrades,[70] to whom he offered many insufficient excuses for his delay. The vindictive Lewis had, meanwhile, determined to satisfy his wounded pride and frustrated ambition, by taking the most signal vengeance of Matthioli; as we find by the following note from Louvois to his creature, St. Mars, dated, St. Germain, April 27th, 1679.--“The King has sent orders to the Abbé d’Estrades, to try and arrest a man, with whose conduct his Majesty has reason to be dissatisfied; of which he has commanded me to acquaint you, in order that you may not object to receiving him when he shall be sent to you; and that you may guard him in a manner, that not only he may not have communication with any one, but that also he may have cause to repent of his bad conduct; and that it may not be discovered that you have a new prisoner.”[71] Nothing therefore could be more opportune to Estrades, than the arrival of Matthioli at Turin, and accident soon enabled him to lay a successful plan for executing the wishes of the French monarch. The plan he is said to have communicated to the Duchess of Savoy, who consented to the arrest taking place, but objected to its happening on her territories.[72] Matthioli complained much of want of money, occasioned by the expenses of his journies, and the bribes he had been obliged to offer to the Duke’s mistresses. Estrades took this opportunity of forwarding his scheme, by telling him that Catinat, who, under the name of Richemont, commanded the troops destined to take possession of Casale, had considerable sums at his disposal, which he would be happy to make so good a use of as in ministering to his wants; provided he, Matthioli, would give him a meeting on the frontier towards Pignerol, at which also Estrades would be present.[73] Of course, the reason assigned for naming the frontier as the place of rendezvous was, that Catinat could not leave the neighbourhood where his troops were stationed.
