"He has never, never been cross to me, as my step-mother used to be," she thought; "he married me without even knowing who I was, and never asked any cruel questions; and even now, if he knew, I think he would have pity upon me and forgive me."

She sat looking at her husband with an earnest yearning expression in her eyes. It seemed as if she wanted to say something to him, but lacked the courage to approach the subject. He was very ill; it was no time to make any unpleasant communication to him. He had been delirious in the night, and had fancied that Mr. Pawlkatt was present, at an hour when that gentleman was snoring comfortably in his own bed. Isabel had been specially enjoined to keep her husband as quiet as it was possible for an active industrious man, newly stricken down by some unlooked-for malady, to be kept. No; whatever she might have to say to him must be left unspoken for the present. Whatever help he might, under ordinary circumstances, have given her, he was utterly powerless to give her now.

The day in that sick chamber seemed terribly long. Not because Isabel felt any selfish weariness of her task; she was only too anxious to be of use to the man she had so deeply wronged; she was only too eager to do something,—something that Mr. Colborne himself might approve,—as an atonement for her sin. But she was quite unused to sickness; and, being of a hyper-sensitive nature, suffered keenly at the sight of any suffering whatever. If the invalid was restless, she fancied directly that he was worse—much worse—in imminent danger, perhaps: if he rambled a little in his talk betwixt sleeping and waking, she sat with his burning hands clasped in hers, trembling from head to foot: if he fell into a profound slumber, she was seized with a sudden terror, fancying him unnaturally quiet, and was fain to disturb him, in her fear lest he should be sinking into some ominous lethargy.

The Doctor's Wife was not one of those excellent nurses who can settle themselves with cheerful briskness in a sick room, and improve the occasion by the darning of a whole basketful of invalided stockings, reserved for some such opportunity. She was not a nurse who could accept the duties of her position in a businesslike way, and polish off each separate task as coolly as a clerk in a banking-house transacts the work assigned to him. Yet she was very quiet withal,—soft of foot, gentle-handed, tender; and George was pleased to see her sitting in the shadowy room, when he lifted his heavy eyelids a little now and then; he was pleased in a dim kind of way to take his medicine from her hand,—the slender little white hand with tapering fingers,—the hand he had admired as it lay lightly on the moss-grown brickwork of the bridge in Hurstonleigh churchyard on the afternoon when he asked her to be his wife.

Mrs. Gilbert sat all day in her husband's room; but about five in the afternoon George fell into a deep slumber, in which Mr. Pawlkatt found him at a little after six o'clock. Nothing could be better than that tranquil sleep, the surgeon said; and when he was gone, Mrs. Jeffson, who had been sitting in the room for some time, anxious to be of use to her master, suggested that Isabel should go down-stairs and out into the garden to get a breath of fresh air.

"You must be a'most stifled, I should think, sitting all day in this room," Tilly said, compassionately. Mrs. Gilbert's face crimsoned all over, as she answered in a timid, hesitating way:

"Yes; I should like to go down-stairs a little, if you think that George is sure to sleep soundly for a long time; and I know you'll take good care of him. I want to go out somewhere—not very far; but I must go to-night."

The Doctor's Wife sat with her back to the light; and Mrs. Jeffson did not see that sudden tide of crimson that rushed into her face, and faded, as she said this; but George Gilbert's housekeeper gave a sniff of disapproval notwithstanding.

"I should have thought if you was the greatest gadderabout that ever was, you'd have stayed quietly at home while your husband was lying ill, Mrs. Gilbert," she said, sharply; "but of course you know your own business best."

"I'm not going far; only—only a little way on the Briargate Road," Isabel answered, piteously; and then her head sank back against the wall behind her, and she sighed a plaintive, almost heart-broken sigh. Her life was very hard just now,—hard and difficult,—begirt with terror and peril, as she thought.
