In the end horror overtakes her in a manner deftly prefigured by an anecdote in the prologue, but she poisons herself in time. Like the mother of Helen Vaughan in The Great God Pan, she has seen that frightful deity. She is discovered dead in the dark wood beside the cryptic thing she found; and that thing—a whitely luminous statue of Roman workmanship about which dire mediæval rumours had clustered—is affrightedly hammered into dust by the searchers.
In the episodic novel of The Three Impostors, a work whose merit as a whole is somewhat marred by an imitation of the jaunty Stevenson manner, occur certain tales which perhaps represent the highwater mark of Machen's skill as a terror-weaver. Here we find in its most artistic form a favourite weird conception of the author's; the notion that beneath the mounds and rocks of the wild Welsh hills dwell subterraneously that squat primitive race whose vestiges gave rise to our common folk legends of fairies, elves, and the "little people," and whose acts are even now responsible for certain unexplained disappearances, and occasional substitutions of strange dark "changelings" for normal infants. This theme receives its finest treatment in the episode entitled The Novel Of The Black Seal; where a professor, having discovered a singular identity between certain characters scrawled on Welsh limestone rocks and those existing in a prehistoric black seal from Babylon, sets out on a course of discovery which leads him to unknown and terrible things. A queer passage in the ancient geographer Solinus, a series of mysterious disappearances in the lonely reaches of Wales, a strange idiot son born to a rural mother after a fright in which her inmost faculties were shaken; all these things suggest to the professor a hideous connection and a condition revolting to any friend and respecter of the human race.
He hires the idiot boy, who jabbers strangely at times in a repulsive hissing voice, and is subject to odd epileptic seizures. Once, after such a seizure in the professor's study by night, disquieting odours and evidences of unnatural presences are found; and soon after that the professor leaves a bulky document and goes into the weird hills with feverish expectancy and strange terror in his heart. He never returns, but beside a fantastic stone in the wild country are found his watch, money, and ring, done up with catgut in a parchment bearing the same terrible characters as those on the black Babylonish seal and the rock in the Welsh mountains.
The bulky document explains enough to bring up the most hideous vistas.
Professor Gregg, from the massed evidence presented by the Welsh disappearances, the rock inscription, the accounts of ancient geographers, and the black seal, has decided that a frightful race of dark primal beings of immemorial antiquity and wide former diffusion still dwell beneath the hills of unfrequented Wales. Further research has unriddled the message of the black seal, and proved that the idiot boy, a son of some father more terrible than mankind, is the heir of monstrous memories and possibilities. That strange night in the study the professor invoked "the awful transmutation of the hills" by the aid of the black seal, and aroused in the hybrid idiot the horrors of his shocking paternity. He "saw his body swell and become distended as a bladder, while the face blackened. . . ." And then the supreme effects of the invocation appeared, and Professor Gregg knew the stark frenzy of cosmic panic in its darkest form. He knew the abysmal gulfs of abnormality that he had opened, and went forth into the wild hills prepared and resigned.
He would meet the unthinkable "Little People"—and his document ends with a rational observation: "If unhappily I do not return from my journey, there is no need to conjure up here a picture of the awfulness of my fate."
Also in The Three Imposters is the Novel of the White Powder, which approaches the absolute culmination of loathsome fright. Francis Leicester, a young law student nervously worn out by seclusion and overwork, has a prescription filled by an old apothecary none too careful about the state of his drugs. The substance, it later turns out, is an unusual salt which time and varying temperature have accidentally changed to something very strange and terrible; nothing less, in short, than the mediæval vinum sabbati, whose consumption at the horrible orgies of the Witches' Sabbath gave rise to shocking transformations and—if injudiciously used—to unutterable consequences. Innocently enough, the youth regularly imbibes the powder in a glass of water after meals; and at first seems substantially benefited. Gradually, however, his improved spirits take the form of dissipation; he is absent from home a great deal, and appears to have undergone a repellent psychological change. One day an odd livid spot appears on his right hand, and he afterward returns to his seclusion; finally keeping himself shut within his room and admitting none of the household. The doctor calls for an interview, and departs in a palsy of horror, saying that he can do no more in that house. Two weeks later the patient's sister, walking outside, sees a monstrous thing at the sickroom window; and servants report that food left at the locked door is no longer touched. Summons at the door bring only a sound of shuffling and a demand in a thick gurgling voice to be let alone. At last an awful happening is reported by a shuddering housemaid. The ceiling of the room below Leicester's is stained with a hideous black fluid, and a pool of viscid abomination has dripped to the bed beneath. Dr. Haberden, now persuaded to return to the house, breaks down the young man's door and strikes again and again with an iron bar at the blasphemous semiliving thing he finds there. It is "a dark and putrid mass, seething with corruption and hideous rottenness, neither liquid nor solid, but melting and changing." Burning points like eyes shine out of its midst, and before it is dispatched it tries to lift what might have been an arm. Soon afterward the physician, unable to endure the memory of what he has beheld, dies at sea while bound for a new life in America.
Mr. Machen returns to the dæmoniac "Little People" in The Red Hand and The Shining Pyramid; and in The Terror, a wartime story, he treats with very potent mystery the effect of man's modern repudiation of spirituality on the beasts of the world, which are thus led to question his supremacy and to unite for his extermination. Of utmost delicacy, and passing from mere horror into true mysticism, is The Great Return, a story of the Graal, also a product of the war period. Too well known to need description here is the tale of The Bowmen; which, taken for authentic narration, gave rise to the widespread legend of the "Angels of Mons"—ghosts of the old English archers of Crecy and Agincourt who fought in 1914 beside the hard-pressed ranks of England's glorious "Old Contemptibles."
Less intense than Mr. Machen in delineating the extremes of stark fear, yet infinitely more closely wedded to the idea of an unreal world constantly pressing upon ours is the inspired and prolific Algernon Blackwood, amidst whose voluminous and uneven work may be found some of the finest spectral literature of this or any age. Of the quality of Mr.
