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.” Now during all these six months I do not think a day had passed on which I had not had in my mind the dreams (or whatever you like to call them) which I had seen in the Villa Cascana. “It is awful, is it not?” she continued, “and I feel, I can’t help feeling, that he may have----” “Caught it at the villa?” I asked. She looked at me in blank surprise. “Why did you say that?” she asked. “How did you know?” Then she told me. In the unoccupied bedroom a year before there had been a fatal case of cancer. She had, of course, taken the best advice and had been told that the utmost dictates of prudence would be obeyed so long as she did not put anybody to sleep in the room, which had also been thoroughly disinfected and newly white-washed and painted. But---- THE CAT
