This, as I said, interested Bourgonef immensely. He seemed to enter completely into the minds of the sorrowing, pleading parents, and the sorrowing, denying lover. He appreciated and expounded their motives with a subtlety and delicacy of perception which surprised and delighted me. It showed the refinement of his moral nature. But, at the same time, it rendered his minor degree of interest in the other episodes of the story, those which had a more direct and overpowering appeal to the heart, a greater paradox. Human nature is troubled in the presence of all mystery which has not by long familiarity lost its power of soliciting attention; and for my own part, I have always been uneasy in the presence of moral problems. Puzzled by the contradictions which I noticed in Bourgonef, I tried to discover whether he had any general repugnance to stories of crimes, or any special repugnance to murders, or, finally, any strange repugnance to this particular case now everywhere discussed. And it is not a little remarkable that during three separate interviews, in the course of which I severally, and as I thought artfully, introduced these topics, making them seem to arise naturally out of the suggestion of our talk, I totally failed to arrive at any distinct conclusion. I was afraid to put the direct question: Do you not share the common feeling of interest in criminal stories? This question would doubtless have elicited a categorical reply; but somehow, the consciousness of an arriere-pensee made me shrink from putting such a question. Reflecting on this indifference on a special point, and on the numerous manifestations I had noticed of his sensibility, I came at last to the conclusion that he must be a man of tender heart, whose delicate sensibilities easily shrank from the horrible under every form; and no more permitted him to dwell unnecessarily upon painful facts, than they permit imaginative minds to dwell on the details of an operation. I had not long settled this in my mind before an accident suddenly threw a lurid light upon many details noticed previously, and painfully revived that inexplicable repulsion with which I had at first regarded him. A new suspicion filled my mind, or rather, let me say, a distinct shape was impressed upon many fluctuating suspicions. It scarcely admitted of argument, and at times seemed preposterous, nevertheless it persisted. The mind which in broad daylight assents to all that can be alleged against the absurdities of the belief in apparitions, will often acknowledge the dim terrors of darkness and loneliness--terrors at possibilities of supernatural visitations. In like manner, in the clear daylight of reason I could see the absurdity of my suspicion, but the vague stirrings of feeling remained unsilenced. I was haunted by the dim horrors of a possibility.
