But what threw Gilman into a cold perspiration was the report of a pair of revellers who had been walking past the mouth of the gangway just after midnight. They admitted they had been drunk, but both vowed they had seen a crazily dressed trio furtively entering the dark passageway. There had, they said, been a huge robed negro, a little old woman in rags, and a young white man in his night-clothes. The old woman had been dragging the youth, while around the feet of the negro a tame rat was rubbing and weaving in the brown mud.

Gilman sat in a daze all the afternoon, and Elwood–who had meanwhile seen the papers and formed terrible conjectures from them–found him thus when he came home. This time neither could doubt but that something hideously serious was closing in around them. Between the phantasms of nightmare and the realities of the objective world a monstrous and unthinkable relationship was crystallizing, and only stupendous vigilance could avert still more direful developments. Gilman must see a specialist sooner or later, but not just now, when all the papers were full of this kidnapping business.

Just what had really happened was maddeningly obscure, and for a moment both Gilman and Elwood exchanged whispered theories of the wildest kind. Had Gilman unconsciously succeeded better than he knew in his studies of space and its dimensions? Had he actually slipped outside our sphere to points unguessed and unimaginable? Where–if anywhere–had he been on those nights of demoniac alienage? The roaring twilight abysses–the green hillside–the blistering terrace–the pulls from the stars–the ultimate black vortex–the black man–the muddy alley and the stairs–the old witch and the fanged, furry horror–the bubble-congeries and the little polyhedron–the strange sunburn–the wrist-wound–the unexplained image–the muddy feet–the throat marks–the tales and fears of the superstitious foreigners–what did all this mean? To what extent could the laws of sanity apply to such a case?

There was no sleep for either of them that night, but next day they both cut classes and drowsed. This was April thirtieth, and with the dusk would come the hellish Sabbat-time which all the foreigners and the superstitious old folk feared. Mazurewicz came home at six o’clock and said people at the mill were whispering that the Walpurgis revels would be held in the dark ravine beyond Meadow Hill where the old white stone stands in a place queerly devoid of all plant-life. Some of them had even told the police and advised them to look there for the missing Wolejko child, but they did not believe anything would be done. Joe insisted that the poor young gentleman wear his nickel-chained crucifix, and Gilman put it on and dropped it inside his shirt to humour the fellow.

Late at night the two youths sat drowsing in their chairs, lulled by the praying of the loom-fixer on the floor below. Gilman listened as he nodded, his preternaturally sharpened hearing seeming to strain for some subtle, dreaded murmur beyond the noises in the ancient house. Unwholesome recollections of things in the Necronomicon and the Black Book welled up, and he found himself swaying to infandous rhythms said to pertain to the blackest ceremonies of the Sabbat and to have an origin outside the time and space we comprehend.

Presently he realized what he was listening for–the hellish chant of the celebrants in the distant black valley. How did he know so much about what they expected? How did he know the time when Nahab and her acolyte were due to bear the brimming bowl which would follow the black cock and the black goat? He saw that Elwood had dropped asleep, and tried to call out and waken him. Something, however, closed his throat. He was not his own master. Had he signed the black man’s book after all?

Then his fevered, abnormal hearing caught the distant, windborne notes. Over miles of hill and field and alley they came, but he recognized them none the less. The fires must be lit, and the dancers must be starting in. How could he keep himself from going? What was it that had enmeshed him? Mathematics–folklore–the house–old Keziah–Brown Jenkin…and now he saw that there was a fresh rat-hole in the wall near his couch. Above the distant chanting and the nearer praying of Joe Mazurewicz came another sound–a stealthy, determined scratching in the partitions. He hoped the electric lights would not go out. Then he saw the fanged, bearded little face in the rat-hole–the accursed little face which he at last realized bore such a shocking, mocking resemblance to old Keziah’s–and heard the faint fumbling at the door.

Ahead was the robed black man he had seen in the peaked space in the other dream, while from a lesser distance the old woman was beckoning and grimacing imperiously. Brown Jenkin was rubbing itself with a kind of affectionate playfulness around the ankles of the black man, which the deep mud largely concealed. There was a dark open doorway on the right, to which the black man silently pointed. Into this the grinning crone started, dragging Gilman after her by his pajama sleeves. There were evil-smelling staircases which creaked ominously, and on which the old woman seemed to radiate a faint violet light; and finally a door leading off a landing. The crone fumbled with the latch and pushed the door open, motioning to Gilman to wait, and disappearing inside the black aperture.

The youth’s over-sensitive ears caught a hideous strangled cry, and presently the beldame came out of the room bearing a small, senseless form which she thrust at the dreamer as if ordering him to carry it. The sight of this form, and the expression on its face, broke the spell. Still too dazed to cry out, he plunged recklessly down the noisome staircase and into the mud outside, halting only when seized and choked by the waiting black man. As consciousness departed he heard the faint, shrill tittering of the fanged, rat-like abnormality.

On the morning of the twenty-ninth Gilman awaked into a maelstrom of horror. The instant he opened his eyes he knew something was terribly wrong, for he was back in his old garret room with the slanting wall and ceiling, sprawled on the now unmade bed. His throat was aching inexplicably, and as he struggled to a sitting posture he saw with growing fright that his feet and pajama bottoms were brown with caked mud. For the moment his recollections were hopelessly hazy, but he knew at least that he must have been sleep-walking. Elwood had been lost too deeply in slumber to hear and stop him. On the floor were confused muddy prints, but oddly enough they did not extend all the way to the door. The more Gilman looked at them, the more peculiar they seemed; for in addition to those he could recognize as his there were some smaller, almost round markings–such as the legs of a large chair or a table might make, except that most of them tended to be divided into halves. There were also some curious muddy rat-tracks leading out of a fresh hole and back into it again. Utter bewilderment and the fear of madness racked Gilman as he staggered to the door and saw that there were no muddy prints outside. The more he remembered of his hideous dream the more terrified he felt, and it added to his desperation to hear Joe Mazurewicz chanting mournfully two floors below.

Descending to Elwood’s room he roused his still-sleeping host and began telling of how he had found himself, but Elwood could form no idea of what might really have happened. Where Gilman could have been, how he got back to his room without making tracks in the hall, and how the muddy, furniture-like prints came to be mixed with his in the garret chamber, were wholly beyond conjecture. Then there were those dark, livid marks on his throat, as if he had tried to strangle himself. He put his hands up to them, but found that they did not even approximately fit. While they were talking, Desrochers dropped in to say that he had heard a terrific clattering overhead in the dark small hours. No, there had been no one on the stairs after midnight, though just before midnight he had heard faint footfalls in the garret, and cautiously descending steps he did not like. It was, he added, a very bad time of year for Arkham. The young gentleman had better be sure to wear the crucifix Joe Mazurewicz had given him. Even the daytime was not safe, for after dawn there had been strange sounds in the house–especially a thin, childish wail hastily choked off.

Gilman mechanically attended classes that morning, but was wholly unable to fix his mind on his studies. A mood of hideous apprehension and expectancy had seized him, and he seemed to be awaiting the fall of some annihilating blow. At noon he lunched at the University spa, picking up a paper from the next seat as he waited for dessert. But he never ate that dessert; for an item on the paper’s first page left him limp, wild-eyed, and able only to pay his check and stagger back to Elwood’s room.

There had been a strange kidnapping the night before in Orne’s Gangway, and the two-year-old child of a clod-like laundry worker named Anastasia Wolejko had completely vanished from sight. The mother, it appeared, had feared the event for some time; but the reasons she assigned for her fear were so grotesque that no one took them seriously. She had, she said, seen Brown Jenkin about the place now and then ever since early in March, and knew from its grimaces and titterings that little Ladislas must be marked for sacrifice at the awful Sabbat on Walpurgis Night. She had asked her neighbour Mary Czanek to sleep in the room and try to protect the child, but Mary had not dared. She could not tell the police, for they never believed such things. Children had been taken that way every year ever since she could remember. And her friend Pete Stowacki would not help because he wanted the child out of the way.

But what threw Gilman into a cold perspiration was the report of a pair of revellers who had been walking past the mouth of the gangway just after midnight. They admitted they had been drunk, but both vowed they had seen a crazily dressed trio furtively entering the dark passageway. There had, they said, been a huge robed negro, a little old woman in rags, and a young white man in his night-clothes. The old woman had been dragging the youth, while around the feet of the negro a tame rat was rubbing and weaving in the brown mud.

For three days Gilman and Elwood canvassed the local museums in an effort to identify the strange spiky image, but always without success. In every quarter, however, interest was intense; for the utter alienage of the thing was a tremendous challenge to scientific curiosity. One of the small radiating arms was broken off and subjected to chemical analysis. Professor Ellery found platinum, iron and tellurium in the strange alloy; but mixed with these were at least three other apparent elements of high atomic weight which chemistry was absolutely powerless to classify. Not only did they fail to correspond with any known element, but they did not even fit the vacant places reserved for probable elements in the periodic system. The mystery remains unsolved to this day, though the image is on exhibition at the museum of Miskatonic University.

On the morning of April twenty-seventh a fresh rat-hole appeared in the room where Gilman was a guest, but Dombrowski tinned it up during the day. The poison was not having much effect, for scratchings and scurryings in the walls were virtually undiminished.

Elwood was out late that night, and Gilman waited up for him. He did not wish to go to sleep in a room alone–especially since he thought he had glimpsed in the evening twilight the repellent old woman whose image had become so horribly transferred to his dreams. He wondered who she was, and what had been near her rattling the tin can in a rubbish-heap at the mouth of a squalid courtyard. The crone had seemed to notice him and leer evilly at him–though perhaps this was merely his imagination.

The next day both youths felt very tired, and knew they would sleep like logs when night came. In the evening they drowsily discussed the mathematical studies which had so completely and perhaps harmfully engrossed Gilman, and speculated about the linkage with ancient magic and folklore which seemed so darkly probable. They spoke of old Keziah Mason, and Elwood agreed that Gilman had good scientific grounds for thinking she might have stumbled on strange and significant information. The hidden cults to which these witches belonged often guarded and handed down surprising secrets from elder, forgotten eons; and it was by no means impossible that Keziah had actually mastered the art of passing through dimensional gates. Tradition emphasizes the uselessness of material barriers in halting a witch’s notions, and who can say what underlies the old tales of broomstick rides through the night?

Whether a modern student could ever gain similar powers from mathematical research alone, was still to be seen. Success, Gilman added, might lead to dangerous and unthinkable situations, for who could foretell the conditions pervading an adjacent but normally inaccessible dimension? On the other hand, the picturesque possibilities were enormous. Time could not exist in certain belts of space, and by entering and remaining in such a belt one might preserve one’s life and age indefinitely; never suffering organic metabolism or deterioration except for slight amounts incurred during visits to one’s own or similar planes. One might, for example, pass into a timeless dimension and emerge at some remote period of the earth’s history as young as before.

Whether anybody had ever managed to do this, one could hardly conjecture with any degree of authority. Old legends are hazy and ambiguous, and in historic times all attempts at crossing forbidden gaps seem complicated by strange and terrible alliances with beings and messengers from outside. There was the immemorial figure of the deputy or messenger of hidden and terrible powers–the “Black Man” of the witch-cult, and the “Nyarlathotep” of the Necronomicon. There was, too, the baffling problem of the lesser messengers or intermediaries–the quasi-animals and queer hybrids which legend depicts as witches’ familiars. As Gilman and Elwood retired, too sleepy to argue further, they heard Joe Mazurewicz reel into the house half drunk, and shuddered at the desperate wildness of his whining prayers.

That night Gilman saw the violet light again. In his dream he had heard a scratching and gnawing in the partitions, and thought that someone fumbled clumsily at the latch. Then he saw the old woman and the small furry thing advancing toward him over the carpeted floor. The beldame’s face was alight with inhuman exultation, and the little yellow-toothed morbidity tittered mockingly as it pointed at the heavily-sleeping form of Elwood on the other couch across the room. A paralysis of fear stifled all attempts to cry out. As once before, the hideous crone seized Gilman by the shoulders, yanking him out of bed and into empty space. Again the infinitude of the shrieking abysses flashed past him, but in another second he thought he was in a dark, muddy, unknown alley of foetid odors with the rotting walls of ancient houses towering up on every hand.

Ahead was the robed black man he had seen in the peaked space in the other dream, while from a lesser distance the old woman was beckoning and grimacing imperiously. Brown Jenkin was rubbing itself with a kind of affectionate playfulness around the ankles of the black man, which the deep mud largely concealed. There was a dark open doorway on the right, to which the black man silently pointed. Into this the grinning crone started, dragging Gilman after her by his pajama sleeves. There were evil-smelling staircases which creaked ominously, and on which the old woman seemed to radiate a faint violet light; and finally a door leading off a landing. The crone fumbled with the latch and pushed the door open, motioning to Gilman to wait, and disappearing inside the black aperture.

When the blood was washed away the wrist wound proved very slight, and Gilman puzzled over the location of the two tiny punctures. It occurred to him that there was no blood on the bedspread where he had lain–which was very curious in view of the amount on his skin and cuff. Had he been sleep-walking within his room, and had the rat bitten him as he sat in some chair or paused in some less rational position? He looked in every corner for brownish drops or stains, but did not find any. He had better, he thought, sprinkle flour within the room as well as outside the door–though after all no further proof of his sleep-walking was needed. He knew he did walk and the thing to do now was to stop it. He must ask Frank Elwood for help. This morning the strange pulls from space seemed lessened, though they were replaced by another sensation even more inexplicable. It was a vague, insistent impulse to fly away from his present situation, but held not a hint of the specific direction in which he wished to fly. As he picked up the strange spiky image on the table he thought the older northward pull grew a trifle stronger; but even so, it was wholly overruled by the newer and more bewildering urge.

He took the spiky image down to Elwood’s room, steeling himself against the whines of the loom-fixer which welled up from the ground floor. Elwood was in, thank heaven, and appeared to be stirring about. There was time for a little conversation before leaving for breakfast and college, so Gilman hurriedly poured forth an account of his recent dreams and fears. His host was very sympathetic, and agreed that something ought to be done. He was shocked by his guest’s drawn, haggard aspect, and noticed the queer, abnormal-looking sunburn which others had remarked during the past week.

There was not much, though, that he could say. He had not seen Gilman on any sleep-walking expedition, and had no idea what the curious image could be. He had, though, heard the French-Canadian who lodged just under Gilman talking to Mazurewicz one evening. They were telling each other how badly they dreaded the coming of Walpurgis Night, now only a few days off; and were exchanging pitying comments about the poor, doomed young gentleman. Desrochers, the fellow under Gilman’s room, had spoken of nocturnal footsteps shod and unshod, and of the violet light he saw one night when he had stolen fearfully up to peer through Gilman’s keyhole. He had not dared to peer, he told Mazurewicz, after he had glimpsed that light through the cracks around the door. There had been soft talking, too–and as he began to describe it his voice had sunk to an inaudible whisper.

Elwood could not imagine what had set these superstitious creatures gossiping, but supposed their imaginations had been roused by Gilman’s late hours and somnolent walking and talking on the one hand, and by the nearness of traditionally-feared May Eve on the other hand. That Gilman talked in his sleep was plain, and it was obviously from Desrochers’ keyhole listenings that the delusive notion of the violet dream-light had got abroad. These simple people were quick to imagine they had seen any odd thing they had heard about. As for a plan of action–Gilman had better move down to Elwood’s room and avoid sleeping alone. Elwood would, if awake, rouse him whenever he began to talk or rise in his sleep. Very soon, too, he must see the specialist. Meanwhile they would take the spiky image around to the various museums and to certain professors; seeking identification and stating that it had been found in a public rubbish-can. Also, Dombrowski must attend to the poisoning of those rats in the walls.

Braced up by Elwood’s companionship, Gilman attended classes that day. Strange urges still tugged at him, but he could sidetrack them with considerable success. During a free period he showed the queer image to several professors, all of whom were intensely interested, though none of them could shed any light upon its nature or origin. That night he slept on a couch which Elwood had had the landlord bring to the second-storey room, and for the first time in weeks was wholly free from disquieting dreams. But the feverishness still hung on, and the whines of the loom-fixer were an unnerving influence.

During the next few days Gilman enjoyed an almost perfect immunity from morbid manifestations. He had, Elwood said, showed no tendency to talk or rise in his sleep; and meanwhile the landlord was putting rat-poison everywhere. The only disturbing element was the talk among the superstitious foreigners, whose imaginations had become highly excited. Mazurewicz was always trying to make him get a crucifix, and finally forced one upon him which he said had been blessed by the good Father Iwanicki. Desrochers, too, had something to say; in fact, he insisted that cautious steps had sounded in the now vacant room above him on the first and second nights of Gilinan’s absence from it. Paul Choynski thought he heard sounds in the halls and on the stairs at night, and claimed that his door had been softly tried, while Mrs. Dombrowski vowed she had seen Brown Jenkin for the first time since All-Hallows. But such naïve reports could mean very little, and Gilman let the cheap metal crucifix hang idly from a knob on his host’s dresser.

For three days Gilman and Elwood canvassed the local museums in an effort to identify the strange spiky image, but always without success. In every quarter, however, interest was intense; for the utter alienage of the thing was a tremendous challenge to scientific curiosity. One of the small radiating arms was broken off and subjected to chemical analysis. Professor Ellery found platinum, iron and tellurium in the strange alloy; but mixed with these were at least three other apparent elements of high atomic weight which chemistry was absolutely powerless to classify. Not only did they fail to correspond with any known element, but they did not even fit the vacant places reserved for probable elements in the periodic system. The mystery remains unsolved to this day, though the image is on exhibition at the museum of Miskatonic University.

So Gilman climbed upstairs again in mental turmoil, convinced that he was either still dreaming or that his somnambulism had run to incredible extremes and led him to depredations in unknown places. Where had he got this outré thing? He did not recall seeing it in any museum in Arkham. It must have been somewhere, though; and the sight of it as he snatched it in his sleep must have caused the odd dream-picture of the balustraded terrace. Next day he would make some very guarded inquiries–and perhaps see the nerve specialist.

Meanwhile he would try to keep track of his somnambulism. As he went upstairs and across the garret hall he sprinkled about some flour which he had borrowed–with a frank admission as to its purpose–from the landlord. He had stopped at Elwood’s door on the way, but had found all dark within. Entering his room, he placed the spiky thing on the table, and lay down in complete mental and physical exhaustion without pausing to undress. From the closed loft above the slanting ceiling he thought he heard a faint scratching and padding, but he was too disorganized even to mind it. That cryptical pull from the north was getting very strong again, though it seemed now to come from a lower place in the sky.

In the dazzling violet light of dream the old woman and the fanged, furry thing came again and with a greater distinctness than on any former occasion. This time they actually reached him, and he felt the crone’s withered claws clutching at him. He was pulled out of bed and into empty space, and for a moment he heard a rhythmic roaring and saw the twilight amorphousness of the vague abysses seething around him. But that moment was very brief, for presently he was in a crude, windowless little space with rough beams and planks rising to a peak just above his head, and with a curious slanting floor underfoot. Propped level on that floor were low cases full of books of every degree of antiquity and disintegration, and in the centre were a table and bench, both apparently fastened in place. Small objects of unknown shape and nature were ranged on the tops of the cases, and in the flaming violet light Gilman thought he saw a counterpart of the spiky image which had puzzled him so horribly. On the left the floor fell abruptly away, leaving a black triangular gulf out of which, after a second’s dry rattling, there presently climbed the hateful little furry thing with the yellow fangs and bearded human face.

The evilly-grinning beldame still clutched him, and beyond the table stood a figure he had never seen before–a tall, lean man of dead black colouration but without the slightest sign of negroid features: wholly devoid of either hair or beard, and wearing as his only garment a shapeless robe of some heavy black fabric. His feet were indistinguishable because of the table and bench, but he must have been shod, since there was a clicking whenever he changed position. The man did not speak, and bore no trace of expression on his small, regular features. He merely pointed to a book of prodigious size which lay open on the table, while the beldame thrust a huge grey quill into Gilman’s right hand. Over everything was a pall of intensely maddening fear, and the climax was reached when the furry thing ran up the dreamer’s clothing to his shoulders and then down his left arm, finally biting him sharply in the wrist just below his cuff. As the blood spurted from this wound Gilman lapsed into a faint.

He awaked on the morning of the twenty-second with a pain in his left wrist, and saw that his cuff was brown with dried blood. His recollections were very confused, but the scene with the black man in the unknown space stood out vividly. The rats must have bitten him as he slept, giving rise to the climax of that frightful dream. Opening the door, he saw that the flour on the corridor floor was undisturbed except for the huge prints of the loutish fellow who roomed at the other end of the garret. So he had not been sleep-walking this time. But something would have to be done about those rats. He would speak to the landlord about them. Again he tried to stop up the hole at the base of the slanting wall, wedging in a candlestick which seemed of about the right size. His ears were ringing horribly, as if with the residual echoes of some horrible noise heard in dreams.

As he bathed and changed clothes he tried to recall what he had dreamed after the scene in the violet-litten space, but nothing definite would crystallize in his mind. That scene itself must have corresponded to the sealed loft overhead, which had begun to attack his imagination so violently, but later impressions were faint and hazy. There were suggestions of the vague, twilight abysses, and of still vaster, blacker abysses beyond them–abysses in which all fixed suggestions were absent. He had been taken there by the bubble-congeries and the little polyhedron which always dogged him; but they, like himself, had changed to wisps of mist in this farther void of ultimate blackness. Something else had gone on ahead–a larger wisp which now and then condensed into nameless approximations of form–and he thought that their progress had not been in a straight line, but rather along the alien curves and spirals of some ethereal vortex which obeyed laws unknown to the physics and mathematics of any conceivable cosmos. Eventually there had been a hint of vast, leaping shadows, of a monstrous, half-acoustic pulsing, and of the thin, monotonous piping of an unseen flute–but that was all. Gilman decided he had picked up that last conception from what he had read in the Necronomicon about the mindless entity Azathoth, which rules all time and space from a black throne at the centre of Chaos.

When the blood was washed away the wrist wound proved very slight, and Gilman puzzled over the location of the two tiny punctures. It occurred to him that there was no blood on the bedspread where he had lain–which was very curious in view of the amount on his skin and cuff. Had he been sleep-walking within his room, and had the rat bitten him as he sat in some chair or paused in some less rational position? He looked in every corner for brownish drops or stains, but did not find any. He had better, he thought, sprinkle flour within the room as well as outside the door–though after all no further proof of his sleep-walking was needed. He knew he did walk and the thing to do now was to stop it. He must ask Frank Elwood for help. This morning the strange pulls from space seemed lessened, though they were replaced by another sensation even more inexplicable. It was a vague, insistent impulse to fly away from his present situation, but held not a hint of the specific direction in which he wished to fly. As he picked up the strange spiky image on the table he thought the older northward pull grew a trifle stronger; but even so, it was wholly overruled by the newer and more bewildering urge.
