a far higher encouragement

D'Artagnan went straight to M. de Treville's. He had reflected that in a few minutes the cardinal would be warned by this cursed stranger, who appeared to be his agent, and he judged, with reason, he had not a moment to lose.
The heart of the young man overflowed with joy. An opportunity presented itself to him in which there would be at the same time glory to be acquired, and money to be gained; and as a far higher encouragement, it brought him into close intimacy with a woman he adored. This chance did, then, for him at once more than he would have dared to ask of Providence.
M. de Treville was in his saloon with his habitual court of gentlemen. D'Artagnan, who was known as a familiar of the house, went straight to his office, and sent word that he wished to see him on something of importance.
D'Artagnan had been there scarcely five minutes when M. de Treville entered. At the first glance, and by the joy which was painted on his countenance, the worthy captain plainly perceived that something new was on foot.
All the way along D'Artagnan had been consulting with himself whether he should place confidence in M. de Treville, or whether he should only ask him to give him CARTE BLANCHE for some secret affair. But M. de Treville had always been so thoroughly his friend, had always been so devoted to the king and queen, and hated the cardinal so cordially, that the young man resolved to tell him everything.D'Artagnan saluted M. de Treville, who held out his hand to him; D'Artagnan pressed it with a respect mixed with gratitude. Since his first arrival at Paris, he had had constant occasion to honor this excellent man, whom he had always found worthy, loyal, and great.
His first visit was to Aramis, at whose residence he ha not been since the famous evening on which he had followed Mme. Bonacieux. Still further, he had seldom seen the young Musketeer; but every time he had seen him, he had remarked a deep sadness imprinted on his countenance.
This evening, especially, Aramis was melancholy and thoughtful. D'Artagnan asked some questions about this prolonged melancholy. Aramis pleaded as his excuse a commentary upon the eighteenth chapter of St. Augustine, which he was forced to write in Latin for the following week, and which preoccupied him a good deal.
After the two friends had been chatting a few moments, a servant from M. de Treville entered, bringing a sealed packet.Aramis called Bazin, and, after having ordered him to join them at Athos's residence, said "Let us go then," at the same time taking his cloak, sword, and three pistols, opening uselessly two or three drawers to see if he could not find stray coin. When well assured this search was superfluous, he followed D'Artagnan, wondering to himself how this young Guardsman should know so well who the lady was to whom he had given hospitality, and that he should know better than himself what had become of her.
