This man, whose name was Nicholas L'Hôte, was the son of an old and trusted follower of the Duc de Villeroy, to whose family his own ancestors had been attached for several generations, while he himself was the godson of the Duke, who had obtained for him the honourable office of secretary to M. de Rochepot, when that nobleman accepted the embassy to Spain. On the return of the Count to France, L'Hôte, whose services were no longer necessary to him, was dismissed, and upon an application to his old patron, was unhesitatingly received into his bureau; where, believing that his loyalty and devotion to himself were beyond all suspicion, he was employed by M. de Villeroy in deciphering his despatches; an occupation which afforded the traitor ample means of continuing his nefarious correspondence with his Spanish confederates. Leyré had no sooner obtained this important information, and moreover convinced himself of its probability by various circumstances connected with L'Hôte which he was careful to learn from other sources, than he proceeded to the residence of M. de Barrault, and solicited an interview on business connected with his government. The ambassador, who was still striving by every method in his power to discover the author of the active and harassing treason by which his official measures were perpetually trammelled, with a vague hope that the object of this request might prove to be connected with the mystery which so disagreeably occupied his thoughts, at once granted the required audience; when Leyré, having explained his own position, and expressed the deepest contrition for his past disloyalty, together with his ardent desire to obliterate, by an essential service to his rightful sovereign, a fault which was now irreparable, proceeded to inform M. de Barrault that he was prepared to reveal a system of treachery which was even at that moment in operation to the prejudice of France; but added that, as in communicating this secret he should be compelled immediately to escape from Spain, he would not consent to do so until the ambassador pledged himself that he should be permitted to return to his own country with a free pardon, and a sufficient pension to secure him against want; and concluded by saying that should it be beyond the power of M. de Barrault to give such a pledge without the royal authority, and that should he consider it necessary to mention him by name, and to state the nature of the promised service to his government, he must entreat him to make this revelation solely to the monarch, and by no means to commit the affair to writing.
