“When the omnibus drove on, and I was alone upon the road, I looked carefully round to ascertain whether the monkey had followed me. To my indescribable relief I saw it nowhere. I can’t describe easily what a shock I had received, and my sense of genuine gratitude on finding myself, as I supposed, quite rid of it.

“I had got out a little before we reached this house, two or three hundred steps. A brick wall runs along the footpath, and inside the wall is a hedge of yew, or some dark evergreen of that kind, and within that again the row of fine trees which you may have remarked as you came.

“This brick wall is about as high as my shoulder, and happening to raise my eyes I saw the monkey, with that stooping gait, on all fours, walking or creeping, close beside me, on top of the wall. I stopped, looking at it with a feeling of loathing and horror. As I stopped so did it. It sat up on the wall with its long hands on its knees looking at me. There was not light enough to see it much more than in outline, nor was it dark enough to bring the peculiar light of its eyes into strong relief. I still saw, however, that red foggy light plainly enough. It did not show its teeth, nor exhibit any sign of irritation, but seemed jaded and sulky, and was observing me steadily.

“I drew back into the middle of the road. It was an unconscious recoil, and there I stood, still looking at it. It did not move.

“With an instinctive determination to try something — anything, I turned about and walked briskly towards town with askance look, all the time, watching the movements of the beast. It crept swiftly along the wall, at exactly my pace.

“Where the wall ends, near the turn of the road, it came down, and with a wiry spring or two brought itself close to my feet, and continued to keep up with me, as I quickened my pace. It was at my left side, so close to my leg that I felt every moment as if I should tread upon it.

“The road was quite deserted and silent, and it was darker every moment. I stopped dismayed and bewildered, turning as I did so, the other way — I mean, towards this house, away from which I had been walking. When I stood still, the monkey drew back to a distance of, I suppose, about five or six yards, and remained stationary, watching me.

“I had been more agitated than I have said. I had read, of course, as everyone has, something about ‘spectral illusions,’ as you physicians term the phenomena of such cases. I considered my situation, and looked my misfortune in the face.

“These affections, I had read, are sometimes transitory and sometimes obstinate. I had read of cases in which the appearance, at first harmless, had, step by step, degenerated into something direful and insupportable, and ended by wearing its victim out. Still as I stood there, but for my bestial companion, quite alone, I tried to comfort myself by repeating again and again the assurance, ‘the thing is purely disease, a well-known physical affection, as distinctly as smallpox or neuralgia. Doctors are all agreed on that, philosophy demonstrates it. I must not be a fool. I’ve been sitting up too late, and I daresay my digestion is quite wrong, and, with God’s help, I shall be all right, and this is but a symptom of nervous dyspepsia.’ Did I believe all this? Not one word of it, no more than any other miserable being ever did who is once seized and riveted in this satanic captivity. Against my convictions, I ............
