As I began to analyze my sensations during the temporary eclipse of the lights, I was conscious of two things. The being, human or other, that had passed me had been light of step and fleet of motion. There had been something uncanny in the ease and speed of that passing. I was without conviction as to its direction, whether up or down, though I inclined to the former notion for the reason that the employment of a concealed switch above seemed the more reasonable argument. And a faint, an almost imperceptible scent, as of a flower, had seemed to be a part of the passing. Mine is a sensitive nostril, and I was confident that it did not betray me in this. The sensation stirred by that faintest of odors had been agreeable; there was nothing suggestive of grave-mold or cerecloth about it. There was in fact something rather delightfully human and contemporaneous in this fellow that pleased and reassured me. That scamp of a revolutionary British soldier, resenting as was his right the application of hemp to his precious neck, had still a grace in him, and a ghost who prowls undaunted about an electric-lighted house in this twentieth century, having his whim with the switches, cannot be an utterly bad fellow. My respect for all who are doomed to walk the night rose as, leaving the lights on clear to the lower hall, I gathered up my matches and started again for the roof. The trunk-room door opened readily, as on my morning inspection of the chimney-pots, but as I glanced up, I saw that the hatch was open. Through the aperture shone the heavens, a square of stars, and bright with the moon's radiance. Pocketing my matches, I ran nimbly up the ladder. X MY BEFUDDLEMENT INCREASES I had been surprised to find the hatch open, but it is not too much to say that I was greatly astonished by what I saw on the moon-flooded roof. There, midway of a flat area that lay between the two larger chimney-pots, two persons were intently engaged, not in ghostly promenading or posturing, or even in audible conversation, but in a spirited bout with foils! The clicking and scraping of the steel testified unmistakably to the reality of their presence. And I was grateful for those sounds! It needed only silence to tumble me back down the trap with chattering teeth, but these were beyond question corporeal beings, albeit rendered weird and fantastical by the oddity of their playground and the soft effulgence of the moon. The vigor of the onset and the skill of the antagonists held me spellbound. I stood with head and shoulders thrust through the opening, staring at this unusual spectacle, and not sure but that after all my eyes were tricking me. "_Touché!_" It was a woman's voice, faint from breathlessness. She threw off her mask and dropped her foil, and with a most human and feminine gesture put up her hands to adjust her hair. It was Cecilia Hollister, in a short skirt and fencing coat!
