The stars were shining when we again took our seats in the boat; and if the scene of our crossing to Jersey was impressive, what shall be said of that of our return?
The Doctor, as before, sat in the stern, an awesome figure, upon which the moon shone with a white radiance that seemed to lift his face out of the surrounding darkness and set it, like an image of frozen horror, before our eyes. Against his breast he held the form of his dead wife, and now and then I saw him stoop as if he were listening for some tokens of life at her set lips. Then he would lift himself again, with hopelessness stamped upon his features, only to lean forward in renewed hope that was again destined to disappointment.
The Inspector and the accompanying physician had taken seats in the bow, and unto me had been assigned the special duty of watching over the Doctor. This I did from a low seat in front of him. I was therefore so close that I heard his laboring breath, and though my heart was full of awe and compassion, I could not prevent myself from bending toward him and saying these words:
"Dr. Zabriskie, the mystery of your crime is no longer a mystery to me. Listen and see if I do not understand your temptation, and how you, a conscientious and God-fearing man, came to slay your innocent neighbor.
"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 if all was false that came to your ears, 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 fake 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 a coach with your friend.
"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's, 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 ready cocked and drawn 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, killing 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.
