The household, however, though it presented an aspect of such gentle calm, was not in reality so undisturbed as it appeared. In Oona's chamber, for one, there was a tumult of new emotions which to the girl were incomprehensible, strange, and terrible, and sweet. Lord Erradeen was but a new acquaintance, she said to herself, as she sat over her fire, with everything hushed and silent about her; nevertheless the tumult of feeling in her heart was all connected with him. Curiously enough, the strange encounter in the garden--of which she had received no explanation--had disappeared from her thoughts altogether. The rise and sudden dawn of a new life in her own being was more near and momentous than any mysterious circumstances, however unlike the common. By-and-by she might come to that--in the mean time a sentiment "_nova, sola, infinita_," occupied all her consciousness. She had known him during the last week only: three times in all, on three several days, had they met; but what a change these three days had made in the life that had been so free and so sweet, full of a hundred interests, without any that was exclusive and absorbing. In a moment, without knowing what was coming, she had been launched into this new world of existence. She was humbled to think of it, yet proud. She felt herself to have become a sort of shadow of him, watching his movements with an anxiety which was without any parallel in her experience, yet at the same time able to interpose for him, when he could not act for himself, to save him. It seemed to Oona suddenly, that everything else had slipped away from her, receding into the distance. The things that had occupied her before were now in the background. All the stage of life was filled with him, and the events of their brief intercourse had become the only occupation of her thoughts. She wondered and blushed as she wandered in that maze of recollections, at her own boldness in assuming the guidance of him; yet felt it to be inevitable--the only thing to be done. And the strange new thrill which ran through her veins when he had appealed to her, when he had implored her to stand by him, came back with an acute sweet mixture of pleasure and pain. She declared to herself, Yes!--with a swelling of her heart--she would stand by him, let it cost her what it might. There had been no love spoken or thought of between them. It was not love: what was it? Friendship, fraternity, the instinctive discovery of one by another, that divination which brings those together who can help each other. It was he, not she, who wanted help--what did it matter which it was? in giving or in receiving it was a new world. But whether it was a demon or an angel that had thus got entrance into that little home of peace and security--who could tell? Whatever it was, it was an inmate hitherto unknown, one that must work changes both in earth and Heaven.
