Perhaps you will consider me the victim of unmanly feelings in this matter. I can only say that those vile crimson drops now seemed as imprinted upon my brain as they had been upon my wrist and my writing-paper. There was something about Leng—about the manner in which he had looked at me, there upon my doorstep—that made me feel almost a stranger in my own home. There was some manner of chill speculativeness behind those indifferent-looking eyes that froze my blood. I could no longer tolerate having the man under my roof without knowing the full breadth of his work.
By some personal caprice unfathomable to me, Leng had recently begun donating his medical services to a few local Houses of Industry. As a result, he was invariably absent from his chambers during the latter part of the afternoon. It was on Monday last, July 11, that I saw him through the front windows of the Cabinet. He was crossing the avenue, clearly on his way to the workhouses.
I knew this was no accident: fate had afforded me this opportunity.
It was with some trepidation that I ascended to the third floor. Leng had changed the lock on the door leading into his room, but I retained a skeleton key which turned the wards and unshot the bolt. I let the door fall open before me, then stepped inside.
Leng had decorated the front room into the semblance of a parlor. I was struck by his choice of decoration: gaudy sporting prints were on the walls, and the tables were aclutter with tabloids and penny-dreadfuls. Leng had always struck me as a man of elegance and refinement; yet this room seemed to reflect the tastes of uncultured youth. It was the sort of dive a pool-room tramp or a girl of low breeding would find inviting. There was a pall of dust over everything, as if Leng had spent little time in the parlor of late.
A heavy brocade curtain had been hung over the doorway leading into the rear rooms. I lifted it aside with the end of my walking stick. I thought I had been prepared for almost anything, but what I found was, perhaps, what I least expected.
The rooms were almost entirely empty. There were at least half a dozen large tables, here and there, whose scarred surfaces bore mute testimony to hours of experimental labor. But they were devoid of furnishing. There was a strong ammoniac smell in the air of these rooms that almost choked me. In one drawer I found several blunt scalpels. All the other drawers I examined were empty, save for dust mites and spiders.
After much searching, I located the spot in the floorboards through which the blood had seeped a few nights before. It seemed to have been etched clean with acid; aqua regia, judging by the odor. I glanced around at the walls then, and noticed other patches, some large, others small, that also seemed to indicate recent cleaning.
I must confess to feeling rather a fool at that moment. There was nothing here to excite alarm; nothing that would rouse the faintest trace of suspicion in even the most perspicacious policeman. And yet the sense of dread refused to wholly leave me. There was something about the oddly decorated parlor, the smell of chemicals, the meticulously cleaned walls and floor, that troubled one. Why were these hidden back rooms clean, while the parlor had been allowed to gather dust?
It was at that moment I remembered the basement.
Years before, Leng had asked, in an offhand way, if he could use the old coal tunnel in the basement for storing excess laboratory equipment. The tunnel had fallen into disuse a few years earlier, with the installation of a new boiler, and I had no need of it myself. I had given him the key and promptly forgotten the matter.
My feelings on descending the cellar stairway behind the Cabinet can scarcely be described. On one occasion I halted, wondering if I should summon an escort. But once again, sane reasoning prevailed. There was no sign of foul play. No—the only thing for it was to proceed myself.
Leng had affixed a padlock to the coal cellar door. Seeing this, I was momentarily overcome by a sense of relief. I had done my utmost; there was nothing else but mount the stairs. I even went so far as to turn around and take the first step. Then I stopped. The same impulse that had brought me this far would not let me leave until I had seen this bad business through.
I raised my foot to kick in the door. Then I hesitated. If I could contrive to remove the lock with a pair of bolt cutters, I reasoned, Leng would think it the work of a sneak-thief.
It was the work of five minutes to retrieve the necessary implement and cut through the hasp of the lock. I dropped it to the ground, then pushed the door wide, allowing the afternoon light to stream down the stairway behind me.
Immediately upon entering, I was overwhelmed with far different sensations than those that had gripped me on the third floor. Whatever work had ceased in Leng’s chambers was, clearly, still active here.
