"I come now to the end of the captain's ghost play; and to the difficulty of trying to explain the other peculiar things. In the first place, it was obvious there was something genuinely strange in the house; which made itself manifest as a Woman. Many different people had seen this Woman, under differing circumstances, so it is impossible to put the thing down to fancy; at the same time it must seem extraordinary that I should have lived two years in the house, and seen nothing; whilst the policeman saw the Woman, before he had been there twenty minutes; the landlord, the detective, and the inspector all saw her. "I can only surmise that _fear_ was in every case the key, as I might say, which opened the senses to the presence of the Woman. The policeman was a highly-strung man, and when he became frightened, was able to see the Woman. The same reasoning applies all 'round. _I_ saw nothing, until I became really frightened; then I saw, not the Woman; but a Child, running away from Something or Someone. However, I will touch on that later. In short, until a very strong degree of fear was present, no one was affected by the Force which made Itself evident, as a Woman. My theory explains why some tenants were never aware of anything strange in the house, whilst others left immediately. The more sensitive they were, the less would be the degree of fear necessary to make them aware of the Force present in the house. "The peculiar shining of all the metal objects in the cellar, had been visible only to me. The cause, naturally I do not know; neither do I know why I, alone, was able to see the shining." "The Child," I asked. "Can you explain that part at all? Why _you_ didn't see the Woman, and why _they_ didn't see the Child. Was it merely the same Force, appearing differently to different people?" "No," said Carnacki, "I can't explain that. But I am quite sure that the Woman and the Child were not only two complete and different entities; but even they were each not in quite the same planes of existence.
