* * * * * I said nothing to my superiors of the thoughts I had had while listening to the above interrogatories. A theory had presented itself to my mind which explained in some measure the mysteries of the Doctor’s conduct, but I wished for time and opportunity to test its reasonableness before submitting it to their higher judgment. And these seemed likely to be given me, for the Inspectors continued divided in their opinion of the blind physician’s guilt, and the District-Attorney, when told of the affair, pooh-poohed it without mercy, and declined to stir in the matter unless some tangible evidence were forthcoming to substantiate the poor Doctor’s self-accusations. “If guilty, why does he shrink from giving his motives,” said he, “and if so anxious to go to the gallows, why does he suppress the very facts calculated to send him there? He is as mad as a March hare, and it is to an asylum he should go and not to a jail.” In this conclusion I failed to agree with him, and as time wore on my suspicions took shape and finally ended in a fixed conviction. Dr. Zabriskie had committed the crime he avowed, but—let me proceed a little further with my story before I reveal what lies beyond that “but.” Notwithstanding Dr. Zabriskie’s almost frenzied appeal for solitude, a man had been placed in surveillance over him in the shape of a young doctor skilled in diseases of the brain. This man communicated more or less with the police, and one morning I received from him the following extracts from the diary he had been ordered to keep. “The Doctor is settling into a deep melancholy from which he tries to rise at times, but with only indifferent success. Yesterday he rode around to all his patients for the purpose of withdrawing his services on the plea of illness. But he still keeps his office open, and to-day I had the opportunity of witnessing his reception and treatment of the many sufferers who came to him for aid. I think he was conscious of my presence, though an attempt had been made to conceal it. For the listening look never left his face from the moment he entered the room, and once he rose and passed quickly from wall to wall, groping with outstretched hands into every nook and corner, and barely escaping contact with the curtain behind which I was hidden. But if he suspected my presence, he showed no displeasure at it, wishing perhaps for a witness to his skill in the treatment of disease. “And truly I never beheld a finer manifestation of practical insight in cases of a more or less baffling nature than I beheld in him to-day. He is certainly a most wonderful physician, and I feel bound to record that his mind is as clear for business as if no shadow had fallen upon it. * * * * *
