Unhappily, however, the demon of ambition by which the Duke was possessed proved too powerful for the generous clemency of the King, and he resumed his treasonable practices; but a misunderstanding having ensued between himself and the false friend by whom he was now betrayed, all the private documents which had been exchanged between himself and the foreign princes through whose aid he trusted to obtain the honours of sovereignty, were communicated on this occasion to the monarch whose dignity and whose confidence he had alike outraged.

A free pardon was accorded to the traitor through whose means Henry was made acquainted with the extent of the intrigue, on condition that he should reside within the precincts of the Court and lend his assistance to convict the Duke of his crime, terms to which the perfidious confidant readily consented; while with a tact worthy of his falsehood, he soon succeeded in reinstating himself in the good graces of the Duke, by professing to be earnestly engaged in France in furthering his interests, and by giving him reason to believe that he was still devoted to his cause.

To this deception, and to his own obstinacy, Biron owed his fate.[179]

The alarming facts which had thus been revealed to them were communicated by Henry and his minister to certain members of the privy council, by whom a report was drawn up and placed in the hands of the Chancellor; and, this preliminary arrangement completed, it was determined to recall the Marechal to Court either to justify himself, or to undergo the penalty of his treason.  In order to effect this object, however, it was necessary to exercise the greatest caution, as Biron was then in Burgundy; and his alarm having already been excited by the evasion of his most confidential agent, they felt that he might, should his suspicions be increased, place himself at the head of the troops under his command, by whom he was idolized, and thus become doubly dangerous.  It was, consequently, only by a subterfuge that there was any prospect of inducing him to approach the capital; and the King, by the advice of Sully, and not without a latent hope that he might be enabled to clear himself of blame, openly asserted that he put no faith in the disclosures which had been made to him, and that he would advise the Marechal to be careful of those about him, whose envy or enmity led them to put a misconstruction upon his motives as well as upon his actions.  The Baron de Luz,[180] the confidential friend of Biron, for whose ear these declarations were especially designed, did not fail to communicate them on the instant to the accused party; while La Fin,[181] by whom he had been betrayed, likewise wrote to assure him that in revealing the conspiracy to the King and the ministers he had been cautious not to utter a word by which he could be personally implicated.  It is certain, however, that the Duke placed little reliance either upon the assertions of Henry, or the assurances of
