Seldom in the course of their old and tried friendship has Jim Burgoyne felt less disposed for the company and conversation of his valued ally, Mrs. Byng, than when he knocks at the door of her sitting-room on the morning following the excursion to Certosa. He cannot talk to her about the Le Marchants, seeing that she has never even heard of their existence; and if out of the abundance of the heart the mouth speaketh, his talk upon any other topic must be scant and jejune indeed. The only cheerful side which his prospective visit turns to him is, that if he were not with Mrs. Byng, he would be with Amelia; and that the friendlily indifferent eyes of the former will, at all events, be less likely than the hungrily loving ones of the latter to detect that he has not slept a wink, and that he has not the remotest idea what he is talking about. If he were to follow his inclination, he would be bestowing his company this morning upon neither friend nor sweetheart, but would be ransacking Florence for the piece of information he had yesterday promised those two woebegone women to procure for them. Even into the very midst of his heartfelt sore compassion for them, there pierces a shamed unwilling flash of elation at the thought of what a stride to intimacy his being entrusted with this commission implies, of what an opening to indefinitely numerous future visits it affords. His determination to conduct the search is at present a good deal more clearly defined than the method in which that search is to be effected. He can consult _Galignani_ as to the names and whereabouts of new arrivals; but they could do that much for themselves. He could examine the visitors' books of the different hotels; but Florence, though a little city, is rich in hostelries, and this course would take time. He could consult Mr. Greenock, the head and fount of all Florentine gossip, and who, since he had seen him in conversation with the object of his inquiries, would probably be able to satisfy them; but his acquaintance with the good-natured newsmonger is not sufficiently intimate for him to be able to pay him a morning visit with any air of probability of having been impelled thereto by a desire for his company; and, moreover, he shrinks with a morbid fear from any action which may lead, however obliquely, to his being himself apprised of the terrible secret which--it is no longer mere matter of conjecture--lies couched somewhere in those two poor creatures' past. And meanwhile he knocks at Mrs. Byng's door, and is quickly bidden enter by a cheerful English voice, the welcoming alacrity of whose tones shames his own want of pleasure in the meeting. But he is too unfortunately honest to express a joy he does not experience, and only says, with a slight accent of reproach as he takes her ready hand, heartily held out: "You should not spring these surprises upon us." She laughs a little guiltily. "It--it was a sudden thought; you see I--I had never seen Perugia."
