“It likes me best,” he said, “but I don’t really know that I like it. And as it won’t drown I think perhaps——”

He shook it off his shoe on to the gravel path and trod on it.

All afternoon the air got heavier and heavier with the Sirocco that was without doubt coming up from the south, and that night again I went up to bed feeling very sleepy; but below my drowsiness, so to speak, there was the consciousness, stronger than before, that there was something wrong in the house, that something dangerous was close at hand. But I fell asleep at once, and—how long after I do not know—either woke or dreamed I awoke, feeling that I must get up at once, or I should be too late. Then (dreaming or awake) I lay and fought this fear, telling myself that I was but the prey of my own nerves disordered by Sirocco or what not, and at the same time quite clearly knowing in another part of my mind, so to speak, that every moment’s delay added to the danger. At last this second feeling became irresistible, and I put on coat and trousers and went out of my room on to the landing. And then I saw that I had already delayed too long, and that I was now too late.

The whole of the landing of the first floor below was invisible under the swarm of caterpillars that crawled there. The folding doors into the sitting-room from which opened the bedroom where I had seen them last night, were shut, but they were squeezing through the cracks of it, and dropping one by one through the keyhole, elongating themselves into mere string as they passed, and growing fat and lumpy again on emerging. Some, as if exploring, were nosing about the steps into the passage at the end of which were Inglis’ rooms, others were crawling on the lowest steps of the staircase that led up to where I stood. The landing, however, was completely covered with them: I was cut off. And of the frozen horror that seized me when I saw that, I can give no idea in words.

Then at last a general movement began to take place, and they grew thicker on the steps that led to Inglis’ room. Gradually, like some hideous tide of flesh, they advanced along the passage, and I saw the foremost, visible by the pale grey luminousness that came from them, reach his door. Again and again I tried to shout and warn him, in terror all the time that they would turn at the sound of my voice and mount my stair instead, but for all my efforts I felt that no sound came from my throat. They crawled along the hinge-crack of his door, passing through as they had done before, and still I stood there making impotent efforts to shout to him, to bid him escape while there was time.

At last the passage was completely empty: they had all gone, and at that moment I was conscious for the first time of the cold of the marble landing on which I stood barefooted. The dawn was just beginning to break in the Eastern sky.

Six months later I met Mrs Stanley in a country house in England. We talked on many subjects and at last she said:

“I don’t think I have seen you since I got that dreadful news about Arthur Inglis a month ago.”

“I haven’t heard,” said I.

“No? He has got cancer. They don’t even advise an operation, for there is no hope of a cure: he is riddled with it, the doctors say.”
