Arthur, who had been only a mite of two years old when he first came to Castle Trevlyn, knew nothing, of course, of any other home; and he and Monica had grown up like brother and sister, and were tenderly attached, perhaps all the more so from radical differences of character and temperament. Their childhood had been uncloudedly happy; they had enjoyed a glorious liberty in their wild Cornish home that could hardly have been accorded to them anywhere else. Monica’s had always been the leading spirit; physically as well as mentally, she had always been the stronger; but he adored her, and emulated her with the zeal and enthusiasm of youth. He followed her wherever she led like a veritable shadow, until that fatal day, five years ago, which had laid him upon a bed of sickness, and had turned Monica in a few hours’ time from a child to a woman.

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.

Lady Diana, on the other hand, had grown more sharp and dictatorial with advancing age. She was a “modish” old lady, who, although quite innocent of such adornments, always suggested the idea of powder and patches, high-heeled shoes and hoops. She generally carried a fan in her hand, dressed richly and quaintly, and looked something like a human parrot, with her hooked nose, keen black eyes, and quick, sharp voice and movements. She had an independent and sufficient income of her own, and divided her time between her London house and her brother’s Cornish castle. She had always expressed it as her intention to provide for Monica, as her father could do little for his daughter, everything going with the entail in the male line; but there was a sort of instinctive hostility between aunt and niece, of which both were well aware, and Lady Diana was always deeply offended and annoyed by Monica’s quiet independence, and her devotion to Arthur.

It was of Monica they were talking this boisterous autumn evening.

“She has a sadly independent spirit,” remarked Lady Diana, sighing, and fanning herself slowly, although the big panelled room was by no means warm. “I often think of her future, and wonder what will become of her.”
