When Mrs. Bizzey brought me the candles, she asked me if I required anything else, as she and Mr. Bizzey were about to retire to the marital couch, which I afterwards ascertained was erected in the scullery. I answered in the negative, and wished her good-night, hearing her afterwards distinctly close the door at the head of the kitchen stairs and descend step by step to the arms of her lord and master. But Mrs. Bizzey’s intrusion had murdered my reverie. I could not take up the chain of thought where she had severed the links. The night air, too, seemed to have grown suddenly damp and chilly, and I pulled down the window sash with a jerk, and taking out my note-book and writing-case drew a chair up to the table and commenced to think, playing idly with my pen the while. Soon the divine afflatus (the symptoms of which every successful writer knows so well) came down upon me. I ceased to think--or rather to be aware that I was thinking. My pen ran over the paper as though some other hand guided it than my own, and I wrote rapidly, filling page after page with a stream of ideas that seemed to pour out of my brain involuntarily. Time is of no account under such circumstances, and I may have been scribbling for one hour or for three, for aught I knew to the contrary, before I was roused to a sense of my position by hearing a footfall sound through the silent, deserted house. Now, although I have described my condition to be such as to render me impervious to outer impressions, I am certain of one thing--that no noise, however slight, had hitherto broken in upon it. It was the complete absence of sound that had permitted my spirit to have full play irrespective of my body; and directly the silence was outraged, my physical life re-asserted its claims, and my senses became all alive to ascertain the cause of it. In another moment the sound was repeated, and I discovered that it was over my head--not under my feet. It could not, then, proceed from either of the old couple, whom I had heard lock themselves up together down below. Who could it be? My first idea, emanating from my landlady’s information that the noise might proceed from rats, I had already dismissed with contempt. It was the reverberation of a footstep. There could be no doubt about that; and my next thought naturally flew to burglars, who were making an attempt on the safes in the offices above. What could I do? I was utterly unarmed, and to go in pursuit of midnight robbers in so defenceless a condition would be simply delivering myself into their power. I certainly might have shied a couple of Jones’ black-lettered books at their heads, for they were ponderous enough to knock any man down, but I might not take a steady aim, and it is better not to attempt at all than to attempt and fail.
