‘Lock your door on the inside,’ I added as I left him, ‘and don’t get up whether the handle moves or not. Then, at all events, you will feel secure till the morrow.’

‘Keys won’t keep them out,’ muttered Dawson, as he entered his sleeping apartment.

But I would not notice the allusion, though I understood it.

I went up to bed with my wife as usual; and it was not until I saw she was sound asleep that, habited in my dressing-gown and slippers, I ventured to creep softly out of the room and take my way downstairs again.

It was then about twelve o’clock. The moonlight was as bright as it had been the night before, and made every object distinctly visible. From the loud snoring which proceeded from Dawson’s room, I concluded that my opiate had taken due effect, and that I should be permitted to hold my vigil undisturbed. In one hand I grasped a loaded revolver, and in the other a huge knotted stick, so determined was I not to be taken by my tormentors at a disadvantage. I turned into the general sitting-room, which opened on the hall. All was as we had left it; and I ensconced myself on one of the large old-fashioned sofas, trusting to my curiosity to keep me awake.

It was weary waiting. I heard one and then two sound from the big clock in the hall; still there was no other noise to break the silence. I began to relapse into my first belief that the whole business was due to imagination. From this I passed to self-satisfaction; self-satisfaction induced inertion, and inertion brought on heavy sleep. How long I slept I do not know, but I had reason afterwards to think, not more than half-an-hour.

However, that point is immaterial. But what waked me—waked me so completely that in a moment all my faculties were as clear as daylight—was the sound of a hoarse breathing. I sat up on the sofa and rubbed my eyes.

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.

I rushed after the clumping feet into the hall; and I heard them slowly and painfully, and yet most distinctly, commence to toil up the staircase. But before they had reached the first landing, and just as I was about to follow in their wake, my attention was distracted by another sound, which appeared to be close at my elbow—the sound of which Dawson had complained the night before—that of a creeping step, and a stifled sobbing, as though a woman were feeling her way along the passage in the dark. I could discern the feeble touch as it felt along the wall, and then placed an uncertain hold upon the banisters—could hear the catching breath, which dared not rise into a cry, and detect the fear which caused the feet to advance and retreat, and advance a little way again, and then stop, as though dread of some unknown calamity overpowered every other feeling. Meanwhile, the clumping steps, that had died away in the distance, turned, and appeared to be coming downstairs again. The moon streamed brightly in at the landing window. Had a form been visible, it would have been as distinctly seen as by day. I experienced a sense of coming horror, and drew back in the shadow of the wall. As the heavy footsteps gained the lower landing, I heard a start—a scuffle—a faint cry of ‘Father!’ and then a curse—the flash of a firearm—a groan—and I remember nothing more.
