have experienced a curious disturbance in—not in my physical region primarily. I mean my nerves are all right, and my body is all right. I have no delusions exactly, but my spirit is tortured by a calamitous fear which first came upon me in a strange manner."
John Silence leaned forward a moment and took the speaker's hand and held it in his own for a few brief seconds, closing his eyes as he did so. He was not feeling his pulse, or doing any of the things that doctors ordinarily do; he was merely absorbing into himself the main note of the man's mental condition, so as to get completely his own point of view, and thus be able to treat his case with true sympathy. A very close observer might perhaps have noticed that a slight tremor ran through his frame after he had held the hand for a few seconds.
"Tell me quite frankly, Mr. Pender," he said soothingly, releasing the hand, and with deep attention in his manner, "tell me all the steps that led to the beginning of this invasion. I mean tell me what the particular drug was, and why you took it, and how it affected you—"
"Then you know it began with a drug!" cried the author, with undisguised astonishment.
"I only know from what I observe in you, and in its effect upon myself. You are in a surprising psychical condition. Certain portions of your atmosphere are vibrating at a far greater rate than others. This is the effect of a drug, but of no ordinary drug. Allow me to finish, please. If the higher rate of vibration spreads all over, you will become, of course, permanently cognisant of a much larger world than the one you know normally. If, on the other hand, the rapid portion sinks back to the usual rate, you will lose these occasional increased perceptions you now have."
"You amaze me!" exclaimed the author; "for your words exactly describe what I have been feeling—"
"I mention this only in passing, and to give you confidence before you approach the account of your real affliction," continued the doctor. "All perception, as you know, is the result of vibrations; and clairvoyance simply means becoming sensitive to an increased scale of vibrations. The awakening of the inner senses we hear so much about means no more than that. Your partial clairvoyance is easily explained. The only thing that puzzles me is how you managed to procure the drug, for it is not easy to get in pure form, and no adulterated tincture could have given you the terrific impetus I see you have acquired. But, please proceed now and tell me your story in your own way."
"This Cannabis indica," the author went on, "came into my possession last autumn while my wife was away. I need not explain how I got it, for that has no importance; but it was the genuine fluid extract, and I could not resist the temptation to make an experiment. One of its effects, as you know, is to induce torrential laughter—"
"Yes: sometimes."
"—I am a writer of humorous tales, and I wished to increase my own sense of laughter—to see the ludicrous from an abnormal point of view. I wished to study it a bit, if possible, and—"
"Tell me!"
"I took an experimental dose. I starved for six hours to hasten the effect, locked myself into this room, and gave orders not to be disturbed. Then I swallowed the stuff and waited."
"And the effect?"
"I waited one hour, two, three, four, five hours. Nothing happened. No laughter came, but only a great weariness instead. Nothing in the room or in my thoughts came within a hundred miles of a humorous aspect."
"Always a most uncertain drug," interrupted the doctor. "We make very small use of it on that account."
"At two o'clock in the morning I felt so hungry and tired that I decided to give up the experiment and wait no longer. I drank some milk and went upstairs to bed. I felt flat and disappointed. I fell asleep at once and must have slept for about an hour, when I awoke suddenly with a great noise in my ears. It was the noise of my own laughter! I was simply shaking with merriment. At first I was bewildered and thought I had been laughing in dreams, but a moment later I remembered the drug, and was delighted to think that after all I had got an effect. It had been working all along, only I had miscalculated the time. The only unpleasant thing then was an odd feeling that I had not waked naturally, but had been wakened by some one else—deliberately. This came to me as a certainty in the middle of my noisy laughter and distressed me."
"Any impression who it could have been?" asked the doctor, now listening with close attention to every word, very much on the alert.
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—of 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, reassured 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 space 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
