The stopping of the carriage seemed to awaken both from thoughts that separated rather than united them. He turned his face in her direction, and she stretching forth her hand, prepared to lead him from the carriage, without any of that display of timidity which had previously been evident in her manner.

As his guide she seemed to fear nothing; as his lover, everything.

“There is another and a deeper tragedy underlying the outward and obvious one,” was my inward conclusion, as I followed them into the presence of the gentlemen awaiting them.

Dr. Zabriskie’s quiet appearance was in itself a shock to those who had anticipated the feverish unrest of a madman; so was his speech, which was calm, straightforward, and quietly determined.

“I shot Mr. Hasbrouck,” was his steady affirmation, given without any show of frenzy or desperation. “If you ask me why I did it, I cannot answer; if you ask me how, I am ready to state all that I know concerning the matter.”

“But, Dr. Zabriskie,” interposed one of the inspectors, “the why is the most important thing for us to consider just now. If you really desire to convince us that you committed this dreadful crime of killing a totally inoffensive man, you should give us some reason for an act so opposed to all your instincts and general conduct.”

But the doctor continued unmoved:

“I had no reason for murdering Mr. Hasbrouck. A hundred questions can elicit no other reply; you had better keep to the how.”

A deep-drawn breath from the wife answered the looks of the three gentlemen to whom this suggestion was offered. “You see,” that breath seemed to protest, “that he is not in his right mind.”

I began to waver in my own opinion, and yet the intuition which has served me in cases seemingly as impenetrable as this bade me beware of following the general judgment.
