You will not keep her.

She is mine, ain't you, Jerry ?' Harold exclaimed, eagerly; while Jerry, who, with a child's instinct scented danger from Harold's manner and associated that danger with the strange man looking so curiously at her, sprang to her feet, which she stamped vigorously, while she cried, ''ess, 'ess, 'ess,' with her face all in wrinkles, and her blue eyes anything but soft and sunny, as they usually were.
In this mood she was not much like Gretchen in the picture, but she was like some one else whom Frank had seen in excited moods, and he grew faint and sick as he watched her, and saw the varying expression of her face and eyes.

The way she shook her head at him and flourished her hands was a way he had seen many times and remembered so well, and he felt as if his heart would leap from his throat as he tried to speak to her.

A turn of the head, a gesture of the hands, a curve of the eyelashes, a tone in the voice, seemed slight actions on which to base a certainty; but Frank did feel certain, and his brain reeled for a second as his thoughts leaped forward years and years until he was an old man, and he wondered if he could bear it and make no sign.
Then, just as he had decided that he could not, the tempter suggested a plan which seemed so feasible and fair that the future, with a secret to guard, did not look so formidable, and to himself he said: 'It is not likely I can ever be positive; and so long as there is a doubt, however small, it would be preposterous to give up what otherwise must come to my children, if not to me; but I will not wrong her more than I can help.' 'Come, little girl, go with me,' he said, in his kindest tones, as he advanced toward her, while Harold went for her cloak and hood.
Jerry knew then that she was expected to go with the stranger, and without Harold, and resisted with all her might.

Standing behind him, as if safe there, and clinging to his coat, she sobbed piteously, intermingling her sobs with 'Ess, 'ess, 'ess,' the only English word she knew, and which she seemed to think would avail in every emergency.
And it did help her now, for Harold pleaded that he might go, too, and when Jerry saw him with his coat and hat, and understood that he was to be her escort, she ceased to sob, and allowing herself to be made ready, was soon in the sleigh, and on her way to Tracy Park..
