"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.

"The 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 passed his hand over his eyes a moment and let the breath escape softly through his teeth. "Yet most damnably 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. But I think now there is nothing further I need ask you." He indulged in a long scrutiny of the author's haggard features, drawing purposely the man's eyes to his own and then meeting them with a look of power and confidence calculated to inspire even the feeblest soul with courage. "And, to begin with," he added, smiling pleasantly, "let me assure you without delay that you need have no alarm, for you are no more insane or deluded than I myself am—"

Pender heaved a deep sigh and tried to return the smile.
