Zillah, thus silent and meditative, and so changed from her old self, might well have awakened the wonder of her friend. But whatever Hilda may have thought, and whatever wonder she may have felt, she kept it all to herself; for she was naturally reticent, and so secretive that she never expressed in words any feelings which she might have about things that went on around her. If Zillah chose to stay by herself, or to sit in her company without speaking a word, it was not in Hilda to question her or to remonstrate with her. She rather chose to accommodate herself to the temper of her friend. She could also be meditative and profoundly silent. While Zillah had been talkative, she had talked with her; now, in her silence, she rivaled her as well. She could follow Zillah in all her moods.
At the end of a month they returned to Chetwynde Castle, and resumed the life which they had been leading there. Zillah's new mood seemed to Hilda, and to others also, to last much longer than any one of those many moods in which she had indulged before. But this proved to be more than a mood. It was a change.
The promise which she had given to the Earl she had tried to fulfill most conscientiously. She really had striven as much as possible to "study." That better understanding, born of affection, which had arisen between them, had formed a new motive within her, and rendered her capable of something like application. But it was not until after her visit to Pomeroy Court that she showed any effort that was at all adequate to the purpose before her. The change that then came over her seemed to have given her a new control over herself. And so it was that, at last, the hours devoted to her studies were filled up by efforts that were really earnest, and also really effective.
Under these circumstances, it happened that Zillah began at last to engross Gualtier's attention altogether, during the whole of the time allotted to her; and if he had sought ever so earnestly, he could not have found any opportunity for a private interview with Hilda. What her wishes might be was not visible; for, whether she wished it or not, she did not, in any way, show it. She was always the same--calm, cool, civil, to her music-teacher, and devoted to her own share of the studies. Those little "asides" in which they had once indulged were now out of the question; and, even if a favorable occasion had arisen, Gualtier would not have ventured upon the undertaking. He, for his part, could not possibly know her thoughts: whether she was still cherishing her old designs, or had given them up altogether. He could only stifle his impatience, and wait, and watch, and wait. But how was it with her? Was she, too, watching and waiting for some opportunity? He thought so. But with what aim, or for what purpose? That was the puzzle. Yet that there was something on her mind which she wished to communicate to him he knew well; for it had at last happened that Hilda had changed in some degree from her cool and undemonstrative manner. He encountered sometimes--or thought that he encountered--an earnest glance which she threw at him, on greeting him, full of meaning, which told him this most plainly. It seemed to him to say: Wait, wait, wait; when the time comes. I have that to say which you will be glad to learn. What it might be he knew not, nor could he conjecture; but he thought that it might still refer to the secret of that mysterious cipher which had baffled them both.
