But, as I say, it was not till the winter during which we lately renewed acquaintance with our heroine that the personage in question made again a continuous stay in Rome. Isabel now saw more of her than she had done since her marriage; but by this time Isabel's needs and inclinations had considerably changed. It was not at present to Madame Merle that she would have applied for instruction; she had lost the desire to know this lady's clever trick. If she had troubles she must keep them to herself, and if life was difficult it would not make it easier to confess herself beaten. Madame Merle was doubtless of great use to herself and an ornament to any circle; but was she—would she be—of use to others in periods of refined embarrassment? The best way to profit by her friend—this indeed Isabel had always thought—was to imitate her, to be as firm and bright as she. She recognised no embarrassments, and Isabel, considering this fact,determined for the fiftieth time to brush aside her own.It seemed to her too, on the renewal of an intercourse which had virtually been interrupted, that her old ally was different, was almost detached—pushing to the extreme a certain rather artificial fear of being indiscreet. Ralph Touchett, we know, had been of the opinion that she was prone to exaggeration, to forcing the note—was apt, in the vulgar phrase, to overdo it. Isabel had never admitted this charge—had never indeed quite understood it; Madame Merle's conduct,to her perception, always bore the stamp of good taste,was always "quiet." But in this matter of not wishing to intrude upon the inner life of the Osmond family it at last occurred to our young woman that she overdid a little. That of course was not the best taste; that was rather violent. She remembered too much that Isabel was married; that she had now other interests;that though she, Madame Merle, had known Gilbert Osmond and his little Pansy very well, better almost than any one, she was not after all of the inner circle.She was on her guard; she never spoke of their affairs till she was asked, even pressed—as when her opinion was wanted; she had a dread of seeming to meddle.Madame Merle was as candid as we know, and one day she candidly expressed this dread to Isabel.
