“Please tell me just what you saw when you looked into the den immediately after you heard the shot. You must realize how important this testimony is.” “I do,” was the solemn reply. “I saw, as I told you, both my husband and my daughter looking at Mr. Appleby as he sat in his chair. I did not know then that he was dead, but he must have been dead or dying. The doctors said the death was practically instantaneous.” “And from their attitude or their facial expression could you assume either your husband or daughter to have been the guilty one?” “I can only say they both looked stunned and horrified. Just as one would expect them to look on the occasion of witnessing a horrible tragedy.” “Whether they were responsible for it or not?” “Yes. But I’m not sure the attitude would have been different in the case of a criminal or a witness. I mean the fright and horror I saw on their faces would be the same if they had committed a crime or had seen it done.” Stone considered this. “You may be right,” he said; “I daresay absolute horror would fill the soul in either case, and would produce much the same effect in appearance. Now, let us suppose for a moment, that one or other of the two did do the shooting—wait a moment!” as Mrs. Wheeler swayed uncertainly in her chair. “Don’t faint. I’m supposing this only in the interests of you and yours. Suppose, I say, that either Mr. Wheeler or Miss Wheeler had fired the weapon—as they have both confessed to doing—which would you assume, from their appearance, had done it?” Controlling herself by a strong effort, Sara Wheeler answered steadily, “I could not say. Honestly, to my startled eyes they seemed equally horrified and stunned.” “Of course they would. You see, Mrs. Wheeler, the fact that they both confess it, makes it look as if one of them did do it, and the other having witnessed the deed, takes over the blame to save the guilty one. This sounds harsh, but we have to face the facts. Then, if we can get more or different facts, so much the better.” “You’re suggesting, then, that one of my people did do it, and the other saw it done?” “I’m suggesting that that might be the truth, and so far as we can see now, is the most apparent solution. But I’m not saying it is the truth, nor shall I relax my efforts to find another answer to our problem. And I want to tell you that you have helped materially by withdrawing your own confession. Every step I can take toward the truth is helpful. You have lessened the suspects from three to two; now if I can eliminate another we will have but one; and if I can clear that one, we shall have to look elsewhere.” “That is specious argument, Mr. Stone,” and Sara Wheeler fixed her large, sad eyes upon his face. “For, if you succeeded in elimination of one of the two, it may be you cannot eliminate the third—and then——”
