“Fourth floor,” she said, writing out the room-ticket and handing it to me.

In another moment I was in the lift.

No. 221 was the last door but one at the end of the eastern corridor of the fourth floor. It proved to be a double-bedded room, large, exquisitely ugly, but perfectly appointed in all matters of comfort; in short, it was characteristic of the hotel. I knew that every bedroom in that corridor, and every bedroom in every corridor, presented exactly the same aspect. One instinctively felt the impossibility of anything weird, anything bizarre, anything terrible, entering the precincts of an abode so solid, cheerful, orderly, and middle-class. And yet—but I shall come to that presently.

It will be well for me to relate all that I did that evening. I washed, and then took some valuables out of my bag and put them in my pocket. Then I glanced round the chamber, and amongst other satisfactory details noticed that the electric lights were so fixed that I could read in bed without distressing my eyes. I then went downstairs, by the lift, and into the smoke-room. I had dined on board the express, and so I ordered nothing but a café noir and a packet of Virginian cigarettes. After finishing the coffee I passed into the billiard-room, and played a hundred up with the marker. To show that my nerves were at least as steady as usual that night, I may mention that, although the marker gave me fifty and beat me, I made a break of twenty odd which won his generous approval. The game concluded, I went into the hall and asked the porter if there were any telegrams for me. There were not. I noticed that the porter—it was the night-porter, and he had just come on duty—seemed to have a peculiarly honest and attractive face. Wishing him good-night, I retired to bed. It was something after eleven. I read a chapter of Mr. Walter Crane’s “The Bases of Design,” and having turned off the light, sank into the righteous slumber of a man who has made a pretty break of 20 odd and drunk nothing but coffee. At three o’clock I awoke—not with a start, but rather gradually. I know it was exactly three o’clock because the striking of a notoriously noisy church clock in the neighbourhood was the first thing I heard. But the clock had not wakened me. I felt sure that something else, something far more sinister than a church clock, had been the origin of disturbance.

I listened. Then I heard it again—It. It was the sound of a groan in the next room.

“Someone indisposed, either in body or mind,” I thought lightly, and I tried to go to sleep again. But I could not sleep. The groans continued, and grew more poignant, more fearsome. At last I jumped out of bed and turned on the light—I felt easier when I had turned on the light.

“That man, whoever he is, is dying.” The idea, as it were, sprang at my throat. “He is dying. Only a dying man, only a man who saw Death by his side and trembled before the apparition, could groan like that.”

I put on some clothes, and went into the corridor. The corridor seemed to stretch away into illimitable distance; and far off, miles off, a solitary electric light glimmered. My end of the corridor was a haunt of gloomy shadows, except where the open door allowed the light from my bedroom to illuminate the long monotonous pattern of the carpet. I proceeded to the door next my own—the door of No. 222, and put my ear against the panel. The sound of groans was now much more distinct and more terrifying. Yes. I admit that I was frightened. I called. No answer. “What’s the matter?” I inquired. No answer. “Are you ill, or are you doing this for your own amusement?” It was with a sort of bravado that I threw this last query at the unknown occupant of the room. No answer. Then I tried to open the door, but it was fast.

“Yes,” I said to myself; “either he’s dying or he’s committed a murder and is feeling sorry for it. I must fetch the night-porter.”

Now, hotel lifts are not in the habit of working at three a.m., and so I was compelled to find my way along endless corridors and down flights of stairs apparently innumerable. Here and there an electric light sought with its yellow eye to pierce the gloom. At length I reached the hall, and I well recollect that the tiled floor struck cold into my slippered but sockless feet.
