and the creaking of hidden timbers in the centuried house, were enough to give him a sense of strident pandemonium. The darkness always teemed with unexplained sound—and yet he sometimes shook with fear lest the noises he heard should subside and allow him to hear certain other, fainter, noises which he suspected were lurking behind them.
He was in the changeless, legend-haunted city of Arkham, with its clustering gambrel roofs that sway and sag over attics where witches hid from the King’s men in the dark, olden days of the Province. Nor was any spot in that city more steeped in macabre memory than the gable room which harboured him—for it was this house and this room which had likewise harboured old Keziah Mason, whose flight from Salem Gaol at the last no one was ever able to explain. That was in 1692—the gaoler had gone mad and babbled of a small, white-fanged furry thing which scuttled out of Keziah’s cell, and not even Cotton Mather could explain the curves and angles smeared on the grey stone walls with some red, sticky fluid.
Possibly Gilman ought not to have studied so hard. Non-Euclidean calculus and quantum physics are enough to stretch any brain; and when one mixes them with folklore, and tries to trace a strange background of multi-dimensional reality behind the ghoulish hints of the Gothic tales and the wild whispers of the chimney-corner, one can hardly expect to be wholly free from mental tension. Gilman came from Haverhill, but it was only after he had entered college in Arkham that he began to connect his mathematics with the fantastic legends of elder magic. Something in the air of the hoary town worked obscurely on his imagination. The professors at Miskatonic had urged him to slacken up, and had voluntarily cut down his course at several points. Moreover, they had stopped him from consulting the dubious old books on forbidden secrets that were kept under lock and key in a vault at the university library. But all these precautions came late in the day, so that Gilman had some terrible hints from the dreaded Necronomicon of Abdul Alhazred, the fragmentary Book of Eibon, and the suppressed Unaussprechlichen Kulten of von Junzt to correlate with his abstract formulae on the properties of space and the linkage of dimensions known and unknown.
He knew his room was in the old Witch House—that, indeed, was why he had taken it. There was much in the Essex County records about Keziah Mason’s trial, and what she had admitted under pressure to the Court of Oyer and Terminer had fascinated Gilman beyond all reason. She had told Judge Hathorne of lines and curves that could be made to point out directions leading through the walls of space to other spaces beyond, and had implied that such lines and curves were frequently used at certain midnight meetings in the dark valley of the white stone beyond Meadow Hill and on the unpeopled island in the river. She had spoken also of the Black Man, of her oath, and of her new secret name of Nahab. Then she had drawn those devices on the walls of her cell and vanished.
Gilman believed strange things about Keziah, and had felt a queer thrill on learning that her dwelling was still standing after more than 235 years. When he heard the hushed Arkham whispers about Keziah’s persistent presence in the old house and the narrow streets, about the irregular human tooth-marks left on certain sleepers in that and other houses, about the childish cries heard near May-Eve, and Hallowmass, about the stench often noted in the old house’s attic just after those dreaded seasons, and about the small, furry, sharp-toothed thing which haunted the mouldering structure and the town and nuzzled people curiously in the black hours before dawn, he resolved to live in the place at any cost. A room was easy to secure; for the house was unpopular, hard to rent, and long given over to cheap lodgings. Gilman could not have told what he expected to find there, but he knew he wanted to be in the building where some circumstance had more or less suddenly given a mediocre old woman of the seventeenth century an insight into mathematical depths perhaps beyond the utmost modern delvings of Planck, Heisenberg, Einstein, and de Sitter.
He studied the timber and plaster walls for traces of cryptic designs at every accessible spot where the paper had peeled, and within a week managed to get the eastern attic room where Keziah was held to have practiced her spells. It had been vacant from the first—for no one had ever been willing to stay there long—but the Polish landlord had grown wary about renting it. Yet nothing whatever happened to Gilman till about the time of the fever. No ghostly Keziah flitted through the sombre halls and chambers, no small furry thing crept into his dismal eyrie to nuzzle him, and no record of the witch’s incantations rewarded his constant search. Sometimes he would take walks through shadowy tangles of unpaved musty-smelling lanes where eldritch brown houses of unknown age leaned and tottered and leered mockingly through narrow, small-paned windows. Here he knew strange things had happened once, and there was a faint suggestion behind the surface that everything of that monstrous past might not—at least in the darkest, narrowest, and most intricately crooked alleys—have utterly perished. He also rowed out twice to the ill-regarded island in the river, and made a sketch of the singular angles described by the moss-grown rows of grey standing stones whose origin was so obscure and immemorial.
Gilman’s room was of good size but queerly irregular shape; the north wall slanting perceptibly inward from the outer to the inner end, while the low ceiling slanted gently downward in the same direction. Aside from an obvious rat-hole and the signs of other stopped-up ones, there was no access—nor any appearance of a former avenue of access—to the space which must have existed between the slanting wall and the straight outer wall on the house’s north side, though a view from the exterior shewed where a window had been boarded up at a very remote date. The loft above the ceiling—which must have had a slanting floor—was likewise inaccessible. When Gilman climbed up a ladder to the cobwebbed level loft above the rest of the attic he found vestiges of a bygone aperture tightly and heavily covered with ancient planking and secured by the stout wooden pegs common in colonial carpentry. No amount of persuasion, however, could induce the stolid landlord to let him investigate either of these two closed spaces.
As time wore along, his absorption in the irregular wall and ceiling of his room increased; for he began to read into the odd angles a mathematical significance which seemed to offer vague clues regarding their purpose. Old Keziah, he reflected, might have had excellent reasons for living in a room with peculiar angles; for was it not through certain angles that she claimed to have gone outside the boundaries of the world of space we know? His interest gradually veered away from the unplumbed voids beyond the slanting surfaces, since it now appeared that the purpose of those surfaces concerned the side he was already on.
The touch of brain-fever and the dreams began early in February. For some time, apparently, the curious angles of Gilman’s room had been having a strange, almost hypnotic effect on him; and as the bleak winter advanced he had found himself staring more and more intently at the corner where the down-slanting ceiling met the inward-slanting wall. About this period his inability to concentrate on his formal studies worried him considerably, his apprehensions about the mid-year examinations being very acute. But the exaggerated sense of hearing was scarcely less annoying. Life had become an insistent and almost unendurable cacophony, and there was that constant, terrifying impression of other sounds—perhaps from regions beyond life—trembling on the very brink of audibility. So far as concrete noises went, the rats in the ancient partitions were the worst. Sometimes their scratching seemed not only furtive but deliberate. When it came from beyond the slanting north wall it was mixed with a sort of dry rattling—and when it came from the century-closed loft above the slanting ceiling Gilman always braced himself as if expecting some horror which only bided its time before descending to engulf him utterly.
The dreams were wholly beyond the pale of sanity, and Gilman felt that they must be a result, jointly, of his studies in mathematics and in folklore. He had been thinking too much about the vague regions which his formulae told him must lie beyond the three dimensions we know, and about the possibility that old Keziah Mason—guided by some influence past all conjecture—had actually found the gate to those regions. The yellowed county records containing her testimony and that of her accusers were so damnably suggestive of things beyond human experience—and the descriptions of the darting little furry object which served as her familiar were so painfully realistic despite their incredible details.
That object—no larger than a good-sized rat
