By this unwise and ill-calculated concession the King had afforded an opportunity to the restless and disaffected noble of pursuing a correspondence with Philip as dangerous as it was convenient. Couriers were permitted to come and go unquestioned; and it was not long ere every measure of the French Cabinet was as intimately known at Madrid as it was in the Privy Council of Henry himself. This evil was, moreover, increased by the unconditional pardon which had enabled M. d'Auvergne, after his strange and degrading offer, to return to the Court; and he profited so eagerly by the opportunity which was thus afforded to him that he had little difficulty in convincing the false and vindictive Philip that the moment was at length come in which he might overthrow the power of the sovereign whom he hated. M. de Loménie, however, who, unaware of the promise made by the Count to Henry, became uneasy at the constant communication which the former maintained with the Court of Spain, at length determined to satisfy himself as to its nature, and for this purpose he intercepted some letters, by which he instantly became convinced of the treason meditated against his royal master. Indignant at the discovery which supervened, he suffered his displeasure to reach the ears of the culprit, who forthwith quitted the capital, and hastened to secure himself from arrest in Auvergne, of which province he was the governor, and where he made instant preparations to leave the kingdom should such a step become necessary. It was consequently in vain that the King, when informed of the circumstance, despatched the Sieur d'Escures[257] to summon the Count to his presence in order that he might justify himself. D'Auvergne resolutely refused to quit his retreat until he had received a formal promise from the sovereign that he should be absolved from all blame of whatever description, and received by his Majesty with his accustomed favour, alleging as a pretext for making this demand, that he was on bad terms with all the Princes of the Blood, with the Grand Equerry, and even with his sister, Madame de Verneuil, and that he could not make head against such a host of enemies except he were supported by the King.
