Pender hesitated and tried to smile. He brushed his hair from his forehead with a nervous gesture.

"You must tell me all your impressions, even your fancies; they are quite as important as your certainties."

"I had a vague idea that it was some one connected with my forgotten dream, some one who had been at me in my sleep, some one of great strength and great ability--or great force--quite an unusual personality--and, I was certain, too--a woman."

"A good woman?" asked John Silence quietly.

Pender started a little at the question and his sallow face flushed; it seemed to surprise him. But he shook his head quickly with an indefinable look of horror.

"Evil," he answered briefly, "appallingly evil, and yet mingled with the sheer wickedness of it was also a certain perverseness--the perversity of the unbalanced mind."

He hesitated a moment and looked up sharply at his interlocutor. A shade of suspicion showed itself in his eyes.

"No," laughed the doctor, "you need not fear that I'm merely humouring you, or think you mad. Far from it. Your story interests me exceedingly and you furnish me unconsciously with a number of clues as you tell it.

You see, I possess some knowledge of my own as to these psychic byways."

"I was shaking with such violent laughter," continued the narrator, rea.s.sured in a moment, "though with no clear idea what was amusing me, that I had the greatest difficulty in getting up for the matches, and was afraid I should frighten the servants overhead with my explosions.

When the gas was lit I found the room empty, of course, and the door locked as usual. Then I half dressed and went out on to the landing, my hilarity better under control, and proceeded to go downstairs. I wished to record my sensations. I stuffed a handkerchief into my mouth so as not to scream aloud and communicate my hysterics to the entire household."

"And the presence of this--this--?"

"It was hanging about me all the time," said Pender, "but for the moment it seemed to have withdrawn. Probably, too, my laughter killed all other emotions."

"And how long did you take getting downstairs?"

"I was just coming to that. I see you know all my 'symptoms' in advance, as it were; for, of course, I thought I should never get to the bottom.

Each step seemed to take five minutes, and crossing the narrow hall at the foot of the stairs--well, I could have sworn it was half an hour's journey had not my watch certified that it was a few seconds. Yet I walked fast and tried to push on. It was no good. I walked apparently without advancing, and at that rate it would have taken me a week to get down Putney Hill."

"An experimental dose radically alters the scale of time and s.p.a.ce sometimes--"

"But, when at last I got into my study and lit the gas, the change came horridly, and sudden as a flash of lightning. It was like a douche of icy water, and in the middle of this storm of laughter--"

"Yes; what?" asked the doctor, leaning forward and peering into his eyes.

"--I was overwhelmed with terror," said Pender, lowering his reedy voice at the mere recollection of it.

He paused a moment and mopped his forehead. The scared, hunted look in his eyes now dominated the whole face. Yet, all the time, the corners of his mouth hinted of possible laughter as though the recollection of that merriment still amused him. The combination of fear and laughter in his face was very curious, and lent great conviction to his story; it also lent a bizarre expression of horror to his gestures.

"Terror, was it?" repeated the doctor soothingly.

"Yes, terror; for, though the Thing that woke me seemed to have gone, the memory of it still frightened me, and I collapsed into a chair. Then I locked the door and tried to reason with myself, but the drug made my movements so prolonged that it took me five minutes to reach the door, and another five to get back to the chair again. The laughter, too, kept bubbling up inside me--great wholesome laughter that shook me like gusts of wind--so that even my terror almost made me laugh. Oh, but I may tell you, Dr. Silence, it was altogether vile, that mixture of fear and laughter, altogether vile!

"Then, all at once, the things in the room again presented their funny side to me and set me off laughing more furiously than ever. The bookcase was ludicrous, the arm-chair a perfect clown, the way the clock looked at me on the mantelpiece too comic for words; the arrangement of papers and inkstand on the desk tickled me till I roared and shook and held my sides and the tears streamed down my cheeks. And that footstool!

Oh, that absurd footstool!"

He lay back in his chair, laughing to himself and holding up his hands at the thought of it, and at the sight of him Dr. Silence laughed too.

"Go on, please," he said, "I quite understand. I know something myself of the hashish laughter."

The author pulled himself together and resumed, his face growing quickly grave again.

"So, you see, side by side with this extravagant, apparently causeless merriment, there was also an extravagant, apparently causeless, terror.

The drug produced the laughter, I knew; but what brought in the terror I could not imagine. Everywhere behind the fun lay the fear. It was terror masked by cap and bells; and I became the playground for two opposing emotions, armed and fighting to the death. Gradually, then, the impression grew in me that this fear was caused by the invasion--so you called it just now--of the 'person' who had wakened me; she was utterly evil; inimical to my soul, or at least to all in me that wished for good. There I stood, sweating and trembling, laughing at everything in the room, yet all the while with this white terror mastering my heart.

And this creature was putting--putting her--"

He hesitated again, using his handkerchief freely.

"Putting what?"

"--putting ideas into my mind," he went on, glancing nervously about the room. "Actually tapping my thought-stream so as to switch off the usual current and inject her own. How mad that sounds! I know it, but it's true. It's the only way I can express it. Moreover, while the operation terrified me, the skill with which it was accomplished filled me afresh with laughter at the clumsiness of men by comparison. Our ignorant, bungling methods of teaching the minds of others, of inculcating ideas, and so on, overwhelmed me with laughter when I understood this superior and diabolical method. Yet my laughter seemed hollow and ghastly, and ideas of evil and tragedy trod close upon the heels of the comic. Oh, doctor, I tell you again, it was unnerving!"

John Silence sat with his head thrust forward to catch every word of the story which the other continued to pour out in nervous, jerky sentences and lowered voice.

"You _saw_ nothing--no one--all this time?" he asked.

"Not with my eyes. There was no visual hallucination. But in my mind there began to grow the vivid picture of a woman--large, dark-skinned, with white teeth and masculine features, and one eye--the left--so drooping as to appear almost closed. Oh, such a face--!"

"A face you would recognize 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 super-sensuous 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."
