Fran lost control over herself. "Do you think, knowing what I know, that I'll stand quietly by and see you disgrace your wife as you disgraced…Do you think I'll let you have this Grace Noir for your…to be the third—Do you think I've come out of your past life to fold my hands? I tell you plainly that I'll ruin you with that secret before I'll let you have this woman."

Gregory beheld the awful secret quivering upon her lips. The danger drove him mad. "You devil!" he shouted, rushing upon her.

Fran stood immovable, her eyes fastened on his. "Don't strike me," she said tensely, "don't strike me, I warn you, unless you kill at the first blow."

He staggered back as if her words possessed physical impact. He shrunk in a heap in the library chair and dropped his head upon his arms. To prevent Grace from learning the truth, he could have done almost anything in that first moment of insane terror; but he could not strike Fran.

In the meantime, Mrs. Gregory had been ascending the stairs. They could hear her now, as she softly moved along the hall. No one in the library wished, at that moment, to confront the wife, and absolute silence reigned in the apartment. They heard her pause, when opposite the door, doubtless to assure herself that the typewriter was at work. If she did not hear the clicking of the keys, she might conclude that Grace was absent, and enter.

Gregory raised his haggard head with an air suggesting meditated flight. Even Grace cowered back instinctively. Swift as a shadow, Fran darted on tiptoe to the typewriter, and began pounding upon it vigorously.

Mrs. Gregory passed on her way, and when she reached the farther end of the hall, an old hymn which she had been humming, broke into audible words. Fran snatched the sheet from the typewriter, and bent her head to listen. The words were soft, full of a thrilling faith, a dauntless courage—

"Still all my song shall be
Nearer my God to Thee,
Nearer—"

A door closed. She was gone. Gregory dropped his head with a groan.
