“A friend of yours, or so he called himself, had for a long time filled your ears with tales tending to make you suspicious of your wife and jealous of a certain man whom I will not name. You knew that your friend had a grudge against this man, and so for many months turned a deaf ear to his insinuations. But finally some change which you detected in your wife’s bearing or conversation roused your own suspicions, and you began to doubt her truth and to curse your blindness, which in a measure rendered you helpless. The jealous fever grew and had risen to a high point when one night—a memorable night—this friend met you just as you were leaving town, and with cruel craft whispered in your ear that the man you hated was even then with your wife and that if you would return at once to your home you would find him in her company.
“The demon that lurks at the heart of all men, good or bad, thereupon took complete possession of you, and you answered this false friend by saying that you would not return without a pistol. Whereupon he offered to take you to his house and give you his. You consented, and getting rid of your servant by sending him to Poughkeepsie with your excuses, you entered your friend’s automobile.
“You say you bought the pistol, and perhaps you did, but, however that may be, you left his house with it in your pocket, and declining companionship, walked home, arriving at the Colonnade a little before midnight.
“Ordinarily you have no difficulty in recognizing your own doorstep. But, being in a heated frame of mind, you walked faster than usual and so passed your own house and stopped at that of Mr. Hasbrouck, one door beyond. As the entrances of these houses are all alike, there was but one way by which you could have made yourself sure that you had reached your own dwelling, and that was by feeling for the doctor’s sign at the side of the door. But you never thought of that. Absorbed in dreams of vengeance, your sole impulse was to enter by the quickest means possible. Taking out your night key, you thrust it into the lock. It fitted, but it took strength to turn it, so much strength that the key was twisted and bent by the effort. But this incident, which would have attracted your attention at another time, was lost upon you at this moment. An entrance had been effected, and you were in too excited a frame of mind to notice at what cost, or to detect the small differences apparent in the atmosphere and furnishings of the two houses, trifles which would have arrested your attention under other circumstances, and made you pause before the upper floor had been reached.
“It was while going up the stairs that you took out your pistol, so that by the time you arrived at the front room door you held it already drawn and cocked in your hand. For, being blind, you feared escape on the part of your victim, and so waited for nothing but the sound of a man’s voice before firing. When, therefore, the unfortunate Mr. Hasbrouck, roused by this sudden intrusion, advanced with an exclamation of astonishment, you pulled the trigger, and killed him on the spot. It must have been immediately upon his fall that you recognized from some word he uttered, or from some contact you may have had with your surroundings, that you were in the wrong house and had killed the wrong man; for you cried out, in evident remorse, ‘God! what have I done!’ and fled without approaching your victim.
“Descending the stairs, you rushed from the house, closing the front door behind you and regaining your own without being seen. But here you found yourself baffled in your attempted escape, by two things. First, by the pistol you still held in your hand, and secondly, by the fact that the key upon which you depended for entering your own door was so twisted out of shape that you knew it would be useless for you to attempt to use it. What did you do in this emergency? You have already told us, though the story seemed so improbable at the time, you found nobody to believe it but myself. The pistol you flung far away from you down the pavement, from which, by one of those rare chances which sometimes happen in this world, it was presently picked up by some late passer-by of more or less doubtful character. The door offered less of an obstacle than you had anticipated; for when you turned again you found it, if I am not greatly mistaken, ajar, left so, as we have reason to believe, by one who had gone out of it but a few minutes before in a state which left him but little master of his actions. It was this fact which provided you with an answer when you were asked how you succeeded in getting into Mr. Hasbrouck’s house after the family had retired for the night.
“Astonished at the coincidence, but hailing with gladness the deliverance which it offered, you went in and ascended at once into your wife’s presence; and it was from her lips, and not from those of Mrs. Hasbrouck, that the cry arose which startled the neighbourhood and prepared men’s minds for the tragic words which were shouted a moment later from the next house.
“But she who uttered the scream knew of no tragedy save that which was taking place in her own breast. She had just repulsed a dastardly suitor, and seeing you enter so unexpectedly in a state of unaccountable horror and agitation, was naturally stricken with dismay, and thought she saw your ghost, or what was worse, a possible avenger; while you, having failed to kill the man you sought, and having killed a man you esteemed, let no surprise on her part lure you into any dangerous self-betrayal. You strove instead to soothe her, and even attempted to explain the excitement under which you laboured, by an account of your narrow escape at the station, till the sudden alarm from next door distracted her attention, and sent both your thoughts and hers in a different direction. Not till conscience had fully awakened and the horror of your act had had time to tell upon your sensitive nature, did you breathe forth those vague confessions, which, not being supported by the only explanations which would have made them credible, led her, as well as the police, to consider you affected in your mind. Your pride as a man and your consideration for her as a woman kept you silent, but did not keep the worm from preying upon your heart.
“Am I not correct in my surmises, Dr. Zabriskie, and is not this the true explanation of your crime?”
With a strange look, he lifted up his face.
