Upon that day there had been a terrible end to the mad-cap exploits in cliff-climbing in which the girl had always delighted, and Arthur had been carried back to the castle, as all believed, to die. He did not die, however, but recovered to a suffering, helpless, invalid life; and Monica, who held herself sternly responsible for all, and who had nursed him with a devotion that no mother could have surpassed, now vowed deep down in her heart that her own life should henceforth be devoted to him, that for him she would in future live, and that whatever she could do to lighten his load of pain and make his future happier should be done, at whatever cost to herself, as the one atonement possible for the rashness which had cost him so dear. Five years ago that vow had been recorded, and Monica, from a gay, high-spirited girl, had grown into a pale, silent, thoughtful woman; but she had never wearied of her self-imposed charge—never faltered in her resolution. Arthur was her special, sacred charge. Anything that would conduce to his welfare and happiness was to be accomplished at whatever cost. So far, to tend and care for him had been her aim and object of life, and her deep love had made the office sweet. It had never occurred to her that any contingency could possibly arise by which separation from him should prove the truest test of her devotion. Whilst Arthur and Monica were dreaming their own dreams upstairs, by the light of his dancing fire, no thought of coming changes clouding the horizon of their imagination, downstairs, in the earl’s study, a consultation was being held between him and his sister which would have startled Monica not a little had she heard it. Lord Trevlyn was a tall, stately, grey-headed man of sixty, with a finely-chiselled face and the true Trevlyn cast of countenance that his daughter had inherited. His countenance wore, however, a look of pallor and ill-health that, to a practised eye, denoted weakness of the heart, and his figure had lost its old strength and elasticity, and had grown thin and a little bowed. His expression had much of gentleness mingling with its pride and austerity, as if, with the advance of years, his nature had softened and sweetened, as indeed had been the case.
