This done, he was left for a moment in peace, while the two officials drew aside into the embrasure of the window for a momentary conference. He seemed to notice the hush, for he roused from the torpor into which he was again about to sink, and glanced cautiously about him. The stenographer was busy with his papers, and the other two stood with their backs to him. If help was to come it must come now. This he realized, with a sudden graying of his face which took from it the last vestige of that youthfulness which had been its distinguishing feature; and the finger which had fumbled from time to time in his vest-pocket stole thither once more, bringing forth a little vial which in another moment he raised to his lips. Was there no one to see? No one to stop him? No, the stenographer was closing up his bag; and the two officials deep in conversation. He could drain the last drop unseen. But the sound of the little vial crashing upon the hearthstone whither he had flung it broke the quiet and startled the District Attorney forward in a doubt bordering upon terror. "What is that?" he asked, pointing to the fragments that had just missed the ash heap. "It contained oblivion," was the answer given him in steady tones. "Do you wonder that I sought it? Nothing can save me. I have two minutes before me. I would dedicate them to _her_." His head fell forward on his hands. The clock on the mantel struck. Could it be that when the second hand had circled its small disc twice-- This was the thought of the District Attorney, but not of the Chief Inspector. He had advanced to the desk where Mr. Roberts was still sitting, and remarked with a gravity exceeding any he had hitherto shown: "Mr. Roberts, I have a great disappointment for you. This little vial of yours which held poison yesterday contained nothing but a few drops of harmless liquid to-day. The change was made in the night, by one suspicious of your intention. You will have to face the full consequences of your crime." Carleton Roberts' arms collapsed and his face fell forward upon them, and they heard a groan. Then in the short silence which followed, another and a very different sound broke upon their ears. Seven clear calls from the cuckoo-clock rang out from the room beyond, followed by a woman's smothered cry. It was the one ironic touch the situation had lacked. It pierced the heart of Carleton Roberts and started him in anguish to his feet. "O God!" he cried, "that I should have let that thing of evil shriek out the wicked hours from day to day, only to torment her now with old remembrances! Why did I not crush it to atoms long ago? Why did I leave it hanging on my wall----" With a dash he was in the hall. In another instant he was at the door of his bedroom, followed by the two officials crowding closely up behind him.
