Mabel suddenly ran her white fingers over the keys, and the music brought me back to a realisation of my true position. I had at length discovered the actual house in which the mysterious tragedy had been enacted, and it became impressed upon me that by the exercise of greatest care I might further be enabled to prosecute secret investigations to a successful issue, and at length solve the enigma.
My eyes fixed themselves upon the couch. It was the very spot where I had rested, sightless, helpless, while those strange events had taken place about me. Was it any wonder that I became filled with apprehensions, or that I sat there petrified as one turned to stone?
The square, dark-green antimacassar had been placed in the exact centre of the couch, and sewed down in order to keep it in its place. Where I was sitting was fortunately in the shadow, and when Mabel commenced playing I rose—unsteadily I think—and reseated myself upon the couch, as being more comfortable. Then, while the woman who held me entranced played a selection from the “Trovatore,” I, unnoticed by the others, succeeded in breaking the stitches which tacked the antimacassar to the brocade. The feat was a difficult one, for one does not care to be detected tearing the furniture of one’s hostess. Nevertheless, after ten minutes or so I succeeded in loosening it, and then, as if by the natural movement of my body, commenced to work aside.
The music ceased, and even though all my attention was now centred upon my investigations, I congratulated Mabel upon her accurate execution. Hickman was standing beside her, and together they began to search for some piece he had requested her to play, while Miss Wells, with her hearts and elephants jingling, turned to me and commenced to talk. By this I was, of course, interrupted; nevertheless, some ten minutes later, I rose, and naturally turned back to straighten the rumpled antimacassar. In doing so I managed to lift it and glance beneath.
In an instant the truth was plain. Concealed beneath that square of green crochet-work was a large dark-brown stain upon the brocade. It was the mark of the life-blood of that thin, well-dressed, unknown victim, who had, in an instant, been struck to the heart!
The shock at its discovery caused me to start, but next instant I smoothed out the antimacassar into its former place without attracting any attention, and passed across the room with the motive of inspecting an object which I well remembered discovering when I had made my blind search. Upon a pedestal of black marble stood an exquisite little statuette of a Neapolitan dancing-woman, undoubtedly the work of some Italian master. Without pausing to examine it, I took in its every detail as I passed. It was exactly as I had felt it, and in the self-same spot as on that fatal night.
Beside the couch, as I turned again to look, I saw that a large skin rug had been thrown down. Without doubt it had been placed there to conceal the ugly stain of blood upon the carpet.
And yet there, on the scene of one of the foulest and most cowardly assassinations, we were actually spending the evening quietly, as became a respectable household. The thing seemed absolutely incredible. A dozen times I endeavoured to persuade myself that the whole discovery was but a chimera, arising from my disordered imagination. Nevertheless, it was impossible to disguise from myself the fact that in every detail the truth was borne out. In that very room the unknown man had been struck dead. The marks of his blood still remained as evidence of the truth.
I saw that beside the high lamps at that moment in use, there was a magnificent candelabra suspended from the ceiling, and in this were electric lamps. Then, at the door, I noticed the switch, and knew that it was the same which I had heard turned off by the assassin before leaving the house.
At the end of the room, too, were the folding doors, now concealed by curtains. It was through those very doors that Edna, my mysterious protectress, had passed and repassed to that inner room whence had come the sound of champagne being uncorked and the woman’s piercing scream.
