But before this serene course of life began which Walter found too happy, there was an interval of anxiety and pain. Mrs. Methven did not escape, like the rest, from the consequences of the night's vigil. She got up indeed from her faint, and received with speechless thanksgiving her son back from the dead, as she thought, but had herself to be carried to his room in the old castle, and there struggled for weeks in the grips of fever, brought on, it was said, by the night's exposure. But this she would not herself allow. She had felt it, she said, before she left her home, but concealed it, not to be hindered from obeying her son's summons. If this was true, or invented upon the spur of the moment to prove that in no possible way was Walter to blame, it is impossible to say. But the fever ran very high, and so affected her heart, worn and tired by many assaults, that there was a time when everything was hushed and silenced in the old castle in expectation of death. By-and-by, however, that terror gave place to all the innocent joys of convalescence--soft flitting of women up and down, presents of precious flowers and fruits lighting up the gloom, afternoon meetings when everything that could please her was brought to the recovering mother, and all the loch came with inquiries, with good wishes, and kind offerings. Mrs. Forrester, who was an excellent nurse, and never lost heart, but smiled, and was sure, in the deepest depth, that all would "come right," as she said, took the control of the sick-room, and recovered there the bloom which she had partially lost when Oona was in danger. And Oona stole into the heart of Walter's mother, who had not for long years possessed him sufficiently to make it bitter to her that he should now put a wife before her. Some women never learn this philosophy; and perhaps Mrs. Methven might have resisted it, had not Oona, her first acquaintance on the loch, her tenderest nurse, won her heart. To have the grim old house in which the secret of the Methvens' fate had been laid up, and in which, even to indifferent lookers-on, there had always been an atmosphere of mystery and terror, thus occupied with the most innocent and cheerful commonplaces, the little cares and simple pleasures of a long but hopeful recovery, was confusing and soothing beyond measure to all around. The old servants, who had borne for many years the presence of a secret which was not theirs, felt in this general commotion a relief which words could not express. "No," old Symington said, "it's not ghosts nor any such rubbitch. I never, for my part, here or elsewhere, saw onything worse than myself; but, Miss Oona, whatever it was that you did on the tap of that tower--and how you got there the Lord above knows, for there never was footing for a bird that ever I saw--it has just been blessed. 'Ding down the nests and the craws will flee away.' What am I meaning? Well, that is just what I canna tell. It's a' confusion. I know nothing.
