"A face you would recognise again?"

Pender laughed dreadfully.

"I wish I could forget it," he whispered, "I only wish I could forget it!" Then he sat forward in his chair suddenly, and grasped the doctor's hand with an emotional gesture.

"I _must_ tell you how grateful I am for your patience and sympathy," he cried, with a tremor in his voice, "and--that you do not think me mad. I have told no one else a quarter of all this, and the mere freedom of speech--the relief of sharing my affliction with another--has helped me already more than I can possibly say."

Dr. Silence pressed his hand and looked steadily into the frightened eyes. His voice was very gentle when he replied.

"Your case, you know, is very singular, but of absorbing interest to me," he said, "for it threatens, not your physical existence but the temple of your psychical existence--the inner life. Your mind would not be permanently affected here and now, in this world; but in the existence after the body is left behind, you might wake up with your spirit so twisted, so distorted, so befouled, that you would be _spiritually insane_--a far more radical condition than merely being insane here."

There came a strange hush over the room, and between the two men sitting there facing one another.

"Do you really mean--Good Lord!" stammered the author as soon as he could find his tongue.

"What I mean in detail will keep till a little later, and I need only say now that I should not have spoken in this way unless I were quite positive of being able to help you. Oh, there's no doubt as to that, believe me. In the first place, I am very familiar with the workings of this extraordinary drug, this drug which has had the chance effect of opening you up to the forces of another region; and, in the second, I have a firm belief in the reality of supersensuous occurrences as well as considerable knowledge of psychic processes acquired by long and painful experiment. The rest is, or should be, merely sympathetic treatment and practical application. The hashish has partially opened another world to you by increasing your rate of psychical vibration, and thus rendering you abnormally sensitive. Ancient forces attached to this house have attacked you. For the moment I am only puzzled as to their precise nature; for were they of an ordinary character, I should myself be psychic enough to feel them. Yet I am conscious of feeling nothing as yet. But now, please continue, Mr. Pender, and tell me the rest of your wonderful story; and when you have finished, I will talk about the means of cure."

Pender shifted his chair a little closer to the friendly doctor and then went on in the same nervous voice with his narrative.

"After making some notes of my impressions I finally got upstairs again to bed. It was four o'clock in the morning. I laughed all the way up--at the grotesque banisters, the droll physiognomy of the staircase window, the burlesque grouping of the furniture, and the memory of that outrageous footstool in the room below; but nothing more happened to alarm or disturb me, and I woke late in the morning after a dreamless sleep, none the worse for my experiment except for a slight headache and a coldness of the extremities due to lowered circulation."

"Fear gone, too?" asked the doctor.

"I seemed to have forgotten it, or at least ascribed it to mere nervousness. Its reality had gone, anyhow for the time, and all that day I wrote and wrote and wrote. My sense of laughter seemed wonderfully quickened and my characters acted without effort out of the heart of true humour. I was exceedingly pleased with this result of my experiment. But when the stenographer had taken her departure and I came to read over the pages she had typed out, I recalled her sudden glances of surprise and the odd way she had looked up at me while I was dictating. I was amazed at what I read and could hardly believe I had uttered it."

"And why?"

"It was so distorted. The words, indeed, were mine so far as I could remember, but the meanings seemed strange. It frightened me. The sense was so altered. At the very places where my characters were intended to tickle the ribs, only curious emotions of sinister amus.e.m.e.nt resulted.

Dreadful innuendoes had managed to creep into the phrases. There was laughter of a kind, but it was bizarre, horrible, distressing; and my attempt at a.n.a.lysis only increased my dismay. The story, as it read then, made me shudder, for by virtue of these slight changes it had come somehow to hold the soul of horror, of horror disguised as merriment.

The framework of humour was there, if you understand me, but the characters had turned sinister, and their laughter was evil."

"Can you show me this writing?"

The author shook his head.

"I destroyed it," he whispered. "But, in the end, though of course much perturbed about it, I persuaded myself that it was due to some after-effect of the drug, a sort of reaction that gave a twist to my mind and made me read macabre interpretations into words and situations that did not properly hold them."

"And, meanwhile, did the presence of this person leave you?"

"No; that stayed more or less. When my mind was actively employed I forgot it, but when idle, dreaming, or doing nothing in particular, there she was beside me, influencing my mind horribly--"

"In what way, precisely?" interrupted the doctor.

"Evil, scheming thoughts came to me, visions of crime, hateful pictures of wickedness, and the kind of bad imagination that so far has been foreign, indeed impossible, to my normal nature--"

"The pressure of the Dark Powers upon the personality," murmured the doctor, making a quick note.

"Eh? I didn't quite catch--"

"Pray, go on. I am merely making notes; you shall know their purport fully later."

"Even when my wife returned I was still aware of this Presence in the house; it a.s.sociated itself with my inner personality in most intimate fashion; and outwardly I always felt oddly constrained to be polite and respectful towards it--to open doors, provide chairs and hold myself carefully deferential when it was about. It became very compelling at last, and, if I failed in any little particular, I seemed to know that it pursued me about the house, from one room to another, haunting my very soul in its inmost abode. It certainly came before my wife so far as my attentions were concerned.

"But, let me first finish the story of my experimental dose, for I took it again the third night, and underwent a very similar experience, delayed like the first in coming, and then carrying me off my feet when it did come with a rush of this false demon-laughter. This time, however, there was a reversal of the changed scale of s.p.a.ce and time; it shortened instead of lengthened, so that I dressed and got downstairs in about twenty seconds, and the couple of hours I stayed and worked in the study pa.s.sed literally like a period of ten minutes."

"That is often true of an overdose," interjected the doctor, "and you may go a mile in a few minutes, or a few yards in a quarter of an hour.

It is quite incomprehensible to those who have never experienced it, and is a curious proof that time and s.p.a.ce are merely forms of thought."

"This time," Pender went on, talking more and more rapidly in his excitement, "another extraordinary effect came to me, and I experienced a curious changing of the senses, so that I perceived external things through one large main sense-channel instead of through the five divisions known as sight, smell, touch, and so forth. You will, I know, understand me when I tell you that I _heard_ sights and _saw_ sounds. No language can make this comprehensible, of course, and I can only say, for instance, that the striking of the clock I saw as a visible picture in the air before me. I saw the sounds of the tinkling bell. And in precisely the same way I heard the colours in the room, especially the colours of those books in the shelf behind you. Those red bindings I heard in deep sounds, and the yellow covers of the French bindings next to them made a shrill, piercing note not unlike the chattering of starlings. That brown bookcase muttered, and those green curtains opposite kept up a constant sort of rippling sound like the lower notes of a wood-horn. But I only was conscious of these sounds when I looked steadily at the different objects, and thought about them. The room, you understand, was not full of a chorus of notes; but when I concentrated my mind upon a colour, I heard, as well as saw, it."

"That is a known, though rarely obtained, effect of _Cannabis indica_,"

observed the doctor. "And it provoked laughter again, did it?"

"Only the muttering of the cupboard-bookcase made me laugh. It was so like a great animal trying to get itself noticed, and made me think of a performing bear--which is full of a kind of pathetic humour, you know.

But this mingling of the senses produced no confusion in my brain. On the contrary, I was unusually clear-headed and experienced an intensification of consciousness, and felt marvellously alive and keen-minded.

"Moreover, when I took up a pencil in obedience to an impulse to sketch--a talent not normally mine--I found that I could draw nothing but heads, nothing, in fact, but one head--always the same--the head of a dark-skinned woman, with huge and terrible features and a very drooping left eye; and so well drawn, too, that I was amazed, as you may imagine--"

"And the expression of the face--?"

Pender hesitated a moment for words, casting about with his hands in the air and hunching his shoulders. A perceptible shudder ran over him.

"What I can only describe as--_blackness_," he replied in a low tone; "the face of a dark and evil soul."

"You destroyed that, too?" queried the doctor sharply.

"No; I have kept the drawings," he said, with a laugh, and rose to get them from a drawer in the writing-desk behind him.

"Here is all that remains of the pictures, you see," he added, pushing a number of loose sheets under the doctor's eyes; "nothing but a few scrawly lines. That's all I found the next morning. I had really drawn no heads at all--nothing but those lines and blots and wriggles. The pictures were entirely subjective, and existed only in my mind which constructed them out of a few wild strokes of the pen. Like the altered scale of s.p.a.ce and time it was a complete delusion. These all pa.s.sed, of course, with the pa.s.sing of the drug's effects. But the other thing did not pa.s.s. I mean, the presence of that Dark Soul remained with me. It is here still. It is real. I don't know how I can escape from it."

"It is attached to the house, not to you personally. You must leave the house."

"Yes. Only I cannot afford to leave the house, for my work is my sole means of support, and--well, you see, since this change I cannot even write. They are horrible, these mirthless tales I now write, with their mockery of laughter, their diabolical suggestion. Horrible? I shall go mad if this continues."

He screwed his face up and looked about the room as though he expected to see some haunting shape.

"This influence in this house induced by my experiment, has killed in a flash, in a sudden stroke, the sources of my humour, and though I still go on writing funny tales--I have a certain name you know--my inspiration has dried up, and much of what I write I have to burn--yes, doctor, to burn, before any one sees it."

"As utterly alien to your own mind and personality?"

"Utterly! As though some one else had written it--"

"Ah!"

"And shocking!" He pa.s.sed his hand over his eyes a moment and let the breath escape softly through his teeth. "Yet most d.a.m.nably clever in the consummate way the vile suggestions are insinuated under cover of a kind of high drollery. My stenographer left me of course--and I've been afraid to take another--"

John Silence got up and began to walk about the room leisurely without speaking; he appeared to be examining the pictures on the wall and reading the names of the books lying about. Presently he paused on the hearthrug, with his back to the fire, and turned to look his patient quietly in the eyes. Pender's face was grey and drawn; the hunted expression dominated it; the long recital had told upon him.

"Thank you, Mr. Pender," he said, a curious glow showing about his fine, quiet face; "thank you for the sincerity and frankness of your account.
