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 amusement 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 analysis 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?"
