'I wonder if Arnold will recognise me,' thought Mildred, sorrowfully, that night, as she sat by her window, looking out on her little strip of garden, shimmering in the moonlight. 'I feel so old and changed, and have grown into such quiet ways. Are there some women who are never young, I wonder? Am I one of them? Is it not strange,' she continued, musingly, 'that such beautiful lives as Betha's are struck so suddenly out of the records of years, while I am left to take up the incompleted work she discharged so lovingly? Dear Betha! what a noble heart it was! Arnold reverenced as much as he loved her. How vain to think of replacing, even in the faintest degree; one of the sweetest women this earth ever saw: sweet, because her whole life was in exact harmony with her surroundings.' And there rose before Mildred's eyes a faint image that often haunted her--of a face with smiling eyes, and brown hair just touched with gold--and the small firm hand that, laid on unruly lips, could hush coming wrath, and smooth the angry knitting of baby brows. It was strange, she thought, that neither Olive nor Chrissy were like their mother. Roy's fairness and steady blue eyes were her sole relics--Roy, who was such a pretty little fellow when Mildred had seen him last. Mildred tried to trace out a puzzled thought in her head before she slept that night. A postscript in Arnold's letter, vaguely worded, but most decidedly mysterious, gave rise to a host of conjectures. 'I have just found out that Heriot's business must be settled long before the end of next month--when you come to us. You know him by name and repute, though not personally. I have given him your address. I think it will be better for you both to talk the matter over, and to give it your full consideration, before you start for the north. Make any arrangements you like about the child. Heriot's a good fellow, and deserves to be helped; he has been everything to us through our trouble.' What could Arnold mean? Betha's chatty letters--thoroughly womanly in their gossip--had often spoken of Arnold's friend, Dr. Heriot, and of his kindness to their boys. She had described him as a man of great talents, and an undoubted acquisition to their small society. 'Arnold (who was her universal referee) wondered that a man like Dr. Heriot should bury himself in a Westmorland valley. Some one had told them that he had given up a large West End practice. There was some mystery about him; his wife made him miserable. No one knew the rights or the wrongs of it; but they would rather believe any thing than that he was to blame.' And in another letter she wrote: 'A pleasant evening has just been sadly interrupted. The Bishop was here and one or two others, Dr. Heriot among them; but a telegram summoning him to his wife's deathbed had just reached him.
