I prayed uncle that we might be driven home by the way of Eighty-sixth Street. I wanted to look at the Fairbrother house. I had seen it many times, but I felt that I should see it with new eyes after the story I had just heard in the inspector’s office. That an adventure of this nature could take place in a New York house taxed my credulity. I might have believed it of Paris, wicked, mysterious Paris, the home of intrigue and every redoubtable crime, but of our own homely, commonplace metropolis—the house must be seen for me to be convinced of the fact related. Many of you know the building. It is usually spoken of with a shrug, the sole reason for which seems to be that there is no other just like it in the city. I myself have always considered it imposing and majestic; but to the average man it is too suggestive of Old-World feudal life to be pleasing. On this afternoon—a dull, depressing one—it looked undeniably heavy as we approached it; but interesting in a very new way to me, because of the great turret at one angle, the scene of that midnight descent of two men, each in deadly fear of the other, yet quailing not in their purpose,—the one of flight, the other of pursuit. There was no railing in front of the house. It may have seemed an unnecessary safeguard to the audacious owner. Consequently, the small door in the turret opened directly upon the street, making entrance and exit easy enough for any one who had the key. But the shaft and the small room at the bottom—where were they? Naturally in the center of the great mass, the room being without windows. It was, therefore, useless to look for it, and yet my eye ran along the peaks and pinnacles of the roof, searching for the skylight in which it undoubtedly ended. At last I espied it, and, my curiosity satisfied on this score, I let my eyes run over the side and face of the building for an open window or a lifted shade. But all were tightly closed and gave no more sign of life than did the boarded-up door. But I was not deceived by this. As we drove away, I thought how on the morrow there would be a regular procession passing through this street to see just the little I had seen to-day. The detective’s adventure was like to make the house notorious. For several minutes after I had left its neighborhood my imagination pictured room after room shut up from the light of day, but bearing within them the impalpable aura of those two shadows flitting through them like the ghosts of ghosts, as the detective had tellingly put it.
