"Five actors playing allotted parts on a set stage; and now he, for whom no part had been written, had walked onto the stage unexpectedly, because one of the players had turned rebel, as she had once before. He threw everything out of focus, and them into a fever. The heat and intensity of these flying questions was enough to make a man with even partially trained clairvoyant faculties feel as if he sat in a room filled with flashing fireflies. He took warning and withdrew himself to a cold inner isolation, as he knew how to do, even while laughing and talking with surface ease. It would not do to let his mind become clouded with emotion; or open any door of his imagination. But the impressions that came across that safer inner distance did not make his companions seem less dramatic, more normal: they were still out of focus. Something about the picture was distorted, even to a clear vision. The sense of evil was as strong as ever although the lurking Presence seemed to have retreated into a far background. He saw presently what the distortion was. Their modern figures were somehow incongruous in the old house, not at home. Like actors who had somehow got onto the wrong stage, onto sets with which their voices and costumes clashed. Interlopers. Or else-actors of an old school dressed up in an unbecoming masquerade. Witch House was an old house. Not old as other houses are old, that remain beds of the continuous stream of life, of marriages and births and deaths, of children crying and children laughing, where the past is only part of the pattern, root of the present and the future. Joseph de Quincy, dead nearly a quarter of a thousand years, was still its master: he had been strong, so strong that no later personality could dim or efface him here where he had set his seal. "He left his evil here when he could no longer stay himself," Carew thought. "As a man with diphtheria leaves germs on the things he has handled, the bed he has lain in. Thoughts are tangible things; on their own plane they breed like germs and, unlike germs, they do not die. He may have forgotten; he may even walk the earth in other flesh, but what he has left here lives." As probably it had been meant to do. For the man whose malignance, swollen with the contributions of the centuries, still ensouled these walls would not have cared to build a house or found a family except as a means to an end. Witch House was set like a mold, steeped in ritual atmosphere as a temple. Dangerous business, for who could say that such a temple would not find a god? There are low, non-human beings that coalesce with and feed on such leftover forces: lair in them."
