The room was fully lighted by the moon. I could see into each corner. Nothing was visible. The sound I had heard must then have proceeded from outside the door, which was open; and I turned towards it, fully expecting to see Dawson enter in a somnambulistic condition, brought on by his dreams and my soporific. But he did not appear. I rose and looked into the hall. It was empty, as before. Still the breathing continued, and (as I, with now fully-awakened faculties, discovered) proceeded from a corner of the parlour where stood an old-fashioned secretary and a chair. Not daring to believe my senses, I advanced to the spot and listened attentively. The sound continued, and was unmistakably palpable. The breathing was hoarse and laboured, like that of an old man who was suffering from bronchitis or asthma. Every now and then it was interrupted by a short, roupy cough. What I suffered under this mysterious influence I can hardly tell. Interest and curiosity got the better of my natural horror; but even then I could not but feel that there was something very awful in this strange contact of sound without sight. Presently my eyes were attracted by the chair, which was pushed, without any visible agency, towards the wall. Something rose--I could hear the action of the feet. Something moved--I could hear it approaching the spot where I stood motionless. Something brushed past me, almost roughly--I could feel the contact of a cloth garment against my dressing-gown, and heard the sound of coarsely shod feet leaving the room. My hair was almost standing on end with terror; but I was determined to follow the mystery to its utmost limits, whether my curiosity were satisfied by the attempt or not.
