After I had been some time watching this unintelligible phantasmagoria, and vainly endeavoring to collect a meaning for it, the hall-door opened, and in the momentary gleam of light that shot into the street I saw the dwarf issuing out, muffled to the ears in a cloak. He stood for a moment on the pavement, and adjusting his cloak more carefully about his face, and crushing his hat down over his eyes, he set off at a quick pace in an opposite direction to that part of the street where I was standing. I confess I felt ashamed of the espionage in which I was occupied, and although I followed my mercurial fiend at a safe distance, for the distinct purpose of earthing him wherever he was going, I by no means liked the office which a sort of fatality had forced upon me. But I was somewhat reconciled to it by a secret conviction that the abominable little demon had himself come out upon an equally discreditable expedition, which I soon detected from the infinite pains he took to elude observation. Instead of keeping in the public streets, he darted down numerous dark alleys and lanes, and once with considerable difficulty I chased him through the unsavory depths of a straggling mews, where he doubled in an out with such rapidity as to render it no easy matter to keep upon his track without betraying myself. Two or three times I nearly lost sight of him; and it was not until he emerged out of a gloomy passage, of the existence of which I was until that moment ignorant, into the street where I lived, that I had the least suspicion of the direction he was taking. It was presently evident that his object had some reference to me, for he had no sooner entered the street than he darted into the deep recess of a hall-door, where he stood for full ten minutes crouched and transfixed, looking up at my windows, which were exactly opposite to him. Fortunately I was able to note his movements without being myself perceived, as I lurked in the shadow of the passage from whence he had just issued. The windows of my chambers being dark, I presume he concluded that I was from home; and under that impression, no doubt, he crossed over and knocked stealthily at the door--just as one would knock who did not wish to attract the attention of the inmates, but merely to convey an intimation to the servants. I was seized with a strong impulse to rush upon him suddenly, present myself as the door opened, and confound him on the spot; but I remembered how earnestly Astræa had urged upon me the prudence of avoiding him, and I restrained myself. Stepping cautiously into a doorway, I continued to watch his further proceedings.
