At her words, Hetty and Booth started perceptibly; a quick glance passed between them, as if each was inquiring whether the other had caught the extraordinary words of self-indictment. A puzzled frown appeared on Hetty's brow.

"Perfidy?" interposed Mr. Wrandall. His wife's expression changed from one of bored indifference to sharp inquiry. Leslie paused in the act of lighting a cigarette.

"It is the mildest term I can command," said Sara. "I shall be as brief as possible in stating the case, Mr. Wrandall. You will be surprised to hear that I have taken it upon myself, as the wife of Challis Wrandall and, as I regard it, the one MOST vitally concerned if not interested in the discovery and punishment of the person who took his life,—I say I have taken it upon myself to shield, protect and defend the unhappy young woman who accompanied him to Burton's Inn on that night in March. She has had my constant, my personal protection for more than twenty months."

The Wrandalls leaned forward in their chairs. The match burned Leslie's fingers, and he dropped it without appearing to notice the pain.

"What is this you are saying?" demanded Redmond Wrandall.

"When I left the inn that night, after seeing my husband's body in the little upstairs room, I said to myself that the one who took his life had unwittingly done me a service. He was my husband; I loved him, I adored him. To the end of my days I could have gone on loving him in spite of the cruel return he gave for my love and loyalty. I shall not attempt to tell you of the countless lapses of fidelity on his part. You would not believe me. But he always came back to me with the pitiful love he had for me, and I forgave him his transgressions. These things you know. He confessed many things to you, Mr. Wrandall. He humbled himself to me. Perhaps you will recall that I never complained to you of him. What rancour I had was always directed toward you, his family, who would see no wrong in your king but looked upon me as dirt beneath his feet. There were moments when I could have slain him with my own hands, but my heart rebelled. There were times when he said to me that I ought to kill him for the things he had done. You may now understand what I mean when I say that the girl who went to Burton's Inn with him did me a service. I will not say that I considered her guiltless at the time. On the contrary, I looked upon her in quite a different way. I had no means of knowing then that she was as pure as snow and that he would have despoiled her of everything that was sweet and sacred to her. She took his life in order to save that which was dearer to her than her own life, and she was on her way to pay for her deed with her life if necessary when I came upon her and intervened."

"You—you know who she is?" said Mr. Wrandall, in a low, incredulous voice.

"I have known almost from the beginning. Presently you will hear her story, from her own lips."

Involuntarily four pairs of eyes shifted. They looked blankly at Hetty Castleton.

Speaking swiftly, Sara depicted the scenes and sensations experienced during that memorable motor journey to New York City.
