Shocked beyond all power of self-control by this repetition of what she evidently considered the unhappy ravings of a madman, she let go his arm and turned upon me in frenzy.

"Convince him!" she cried. "Convince him by your questions that he never could have done this fearful thing."I was labouring under great excitement myself, for as a private agent with no official authority such as he evidently attributed to me in the blindness of his passion, I felt the incongruity of my position in the face of a matter of such tragic consequence.

Besides, I agreed with her that he was in a distempered state of mind, and I hardly knew how to deal with one so fixed in his hallucination and with so much intelligence to support it. But the emergency was great, for he was holding out his wrists in the evident expectation of my taking him into instant custody; and the sight was killing his wife, who had sunk on the floor between us, in terror and anguish.

"You say you killed Mr. Hasbrouck," I began. "Where did you get your pistol, and what did you do with it after you left his house?""My husband had no pistol; never had any pistol," put in Mrs.

Zabriskie, with vehement assertion. "If I had seen him with such a weapon--""I threw it away. When I left the house, I cast it as far from me as possible, for I was frightened at what I had done, horribly frightened.""No pistol was ever found," I answered with a smile, forgetting for the moment that he could not see. "If such an instrument had been found in the street after a murder of such consequence, it certainly would have been brought to the police.""You forget that a good pistol is valuable property," he went on stolidly. "Someone came along before the general alarm was given;and seeing such a treasure lying on the sidewalk, picked it up and carried it off. Not being an honest man, he preferred to keep it to drawing the attention of the police upon himself.""Hum, perhaps," said I; "but where did you get it. Surely you can tell where you procured such a weapon, if, as your wife intimates, you did not own one.""I bought it that selfsame night of a friend; a friend whom Iwill not name, since he resides no longer in this country. I--"He paused; intense passion was in his face; he turned towards his wife, and a low cry escaped him, which made her look up in fear.

"I do not wish to go into any particulars," said he. "God forsook me and I committed a horrible crime. When I am punished, perhaps peace will return to me and happiness to her. I would not wish her to suffer too long or too bitterly for my sin.""Constant!" What love was in the cry! It seemed to move him and turn his thoughts for a moment into a different channel.

"Poor child!" he murmured, stretching out his hands by an irresistible impulse towards her. But the change was but momentary, and he was soon again the stem and determined self-accuser. "Are you going to take me before a magistrate?" he asked. "If so, I have a few duties to perform which you are welcome to witness."This was too much; I felt that the time had come for me to disabuse his mind of the impression he had unwittingly formed of me. I therefore said as considerately as I could:

"You mistake my position, Dr. Zabriskie. Though a detective of some experience, I have no connection with the police and no right to intrude myself in a matter of such tragic importance.

If, however, you are as anxious as you say to subject yourself to police examination, I will mention the same to the proper authorities, and leave them to take such action as they think best.""That will be still more satisfactory to me," said he; "for though I have many times contemplated giving myself up, I have still much to do before I can leave my home and practice without injury to others. Good-day; when you want me you will find me here."He was gone, and the poor young wife was left crouching on the floor alone. Pitying her shame and terror, I ventured to remark that it was not an uncommon thing for a man to confess to a crime he had never committed, and assured her that the matter would be inquired into very carefully before any attempt was made upon his liberty.

She thanked me, and slowly rising, tried to regain her equanimity; but the manner as well as the matter of her husband's self-condemnation was too overwhelming in its nature for her to recover readily from her emotions.

"I have long dreaded this," she acknowledged. "For months I have foreseen that he would make some rash communication or insane avowal. If I had dared, I would have consulted some physician about this hallucination of his; but he was so sane on other points that I hesitated to give my dreadful secret to the world.

I kept hoping that time and his daily pursuits would have their effect and restore him to himself. But his illusion grows, and now I fear that nothing will ever convince him that he did not commit the deed of which he accuses himself. If he were not blind I would have more hope, but the blind have so much time for brooding.""I think he had better be indulged in his fancies for the present," I ventured. "If he is labouring under an illusion it might be dangerous to cross him.""If?" she echoed in an indescribable tone of amazement and dread.

"Can you for a moment harbour the idea that he has spoken the truth?""Madam," I returned, with something of the cynicism of my calling, "what caused you to give such an unearthly scream just before this murder was made known to the neighbourhood?"She stared, paled, and finally began to tremble, not, as I now believe, at the insinuation latent in my words, but at the doubts which my question aroused in her own breast.
