That terrible thought had been borne upon her as a suggestion to account for much that she could not understand in the words and the behavior of Ella during that remarkable evening; and, in spite of her remorse and her prayers, she could not rid herself of it. It left its impression upon her mind, upon her heart. Hitherto she had only heard about the way an unlawful passion sweeps over two people, causing them to fling to the winds all considerations of home, of husband, of religion, of honor; and she felt it to be very terrible to be brought face to face with such a power; it seemed to her as terrible as to be brought face to face with that personal Satan in whom she believed.

It only required such a hint as that which had come from George Holland to set her smoldering suspicion--suspicion of a suspicion--in a flame. It had flamed up before him in those words which she had spoken to him. If Ella were guilty, he, George Holland, was to be held responsible for her guilt.

But Ella was not guilty; Herbert Courtland was not guilty.

"No, no, no!" she cried, in the solitude of her chamber. "She did not talk as a guilty woman would talk; and he--he went straight out of the room where I had told him what Mrs. Haddon said about his mother, his sister--straight aboard the yacht; and she----"

All at once the truth flashed upon her; the truth--she felt that it was the truth; and both of them were guiltless. It was for Herbert Courtland that Ella had put on that lovely dress; but she was guiltless, he was guiltless. (Curiously enough, she felt quite as happy in the thought that he was guiltless.) Yes, Ella had come to her wearing that dress instead of waiting for him, and he---- Ah, she now knew what he had meant when he had called her his good angel. She had saved him.

She flung herself on her knees in a passion of thanksgiving to God for having made her the means of saving a soul from hell--yes, for the time being.

And then she began to think what she should do in order that that soul should be saved forever.

It was time for her to dress for dinner before she had finished working out that great question, possibly the greatest question that ever engrossed the attention of a young woman: how to save the soul of a man, not temporarily, but eternally.
