Yet she uttered no word of response, and apparently did not move. I advanced, crossing towards the window, where I believed she must be standing, but with a quick movement my mysterious visitor eluded me, passing me by so near that her warm breath fanned my cheek, and next instant she had escaped and slammed the outer door of my chambers. I stood wondering. Her presence there was most extraordinary. The faithful Parker, too, was absent, a circumstance which aroused misgivings within me. Could this strange female visitor have entered the place with a false key; or was she a mere pilferer whom I had disturbed in her search for plunder? Numbers of female thieves haunt the London streets, and it seemed more than likely that she was one who had ascended the stairs on pretence of selling something or other. At any rate, I had returned at an unexpected moment, or she would not have given vent to that involuntary cry of dismay. I groped about the familiar room in order to ascertain whether it were disordered, but could find nothing whatsoever out of place. I called Parker loudly by name, but all was silence save the quick ticking of the timepiece upon the mantelshelf. The clock of St Clement Danes chimed merrily, then slowly struck the hour. I counted, and found that it was eleven o'clock in the morning. How much had happened during the past fifteen hours! I had twice nearly lost my life. Having cast aside my hat, I sank into my armchair, muddy and dirty, just as I was. My head, where it had been struck in the accident, pained me considerably, and I felt that I had a touch of fever coming on. Yet all my thoughts were concentrated upon the future and what the curious alliance with my strange protectress might bring upon me. Surely no man had ever found himself in a more remarkable situation than I was at that moment; certainly no man could be more mystified and puzzled. Deeply I pondered again and again, but could make nothing of that tangled web of startling facts. By no desire or inclination of my own I had fallen among what appeared to be very undesirable company, and had involuntarily promised to become the assistant of some person whom I could not see. The strange oppression that fell upon me seemed precursory of evil. My wet clothes sticking to me chilled me to the bone, and, with a sudden resolve to shake off the gloomy apprehensions that seemed to have gripped my heart, I rose and passed into my own room to wash and get a change of clothing. The prolonged absence of Parker caused me much wonder. She never went out unless to go into the Strand to purchase the diurnal steak or tri-weekly chop which constituted my chief sustenance; or, perhaps, on Sunday afternoon she would, on rare occasions, go "to take a cup o' tea" with her daughter, who was a music-hall artiste, and lived somewhere off the Kensington Road.
