"I assure you, sir—" I began, when he interrupted me.

"One moment, please," he said, putting his hand into the inside pocket of his black coat and extracting from it an envelope addressed to me. "Let me finish: it is the whim of one who has an affection for you. For ten years I have secretly been at work myself on a story. It is a short one, but it has seemed good to me. I had a double object in seeking you out to-night. I wanted not only to see you, but to read my story to you. No one knows that I have written it; I had intended it as a surprise to my—to my friends. I had hoped to have it published somewhere, and I had come here to seek your advice in the matter. It is a story which I have written and rewritten and rewritten time and time again in my leisure moments during the ten years past, as I have told you. It is not likely that I shall ever write another. I am proud of having done it, but I should be prouder yet if it—if it could in some way help you. I leave it with you, sir, to print or to destroy; and if you print it, to see it in type will be enough for me; to see your name signed to it will be a matter of pride to me. No one will ever be the wiser, for, as I say, no one knows I have written it, and I promise you that no one shall know of it if you decide to do as I not only suggest but ask you to do. No one would believe me after it has appeared as yours, even if I should forget my promise and claim it as my own. Take it. It is yours. You are entitled to it as a slight measure of repayment for the debt of gratitude I owe you."

He pressed the manuscript into my hands, and before I could reply had opened the door and disappeared into the darkness of the street. I rushed to the sidewalk and shouted out to him to return, but I might as well have saved my breath and spared the neighborhood, for there was no answer. Holding his story in my hand, I re-entered the house and walked back into my library, where, sitting and reflecting upon the curious interview, I realized for the first time that I was in entire ignorance as to my visitor's name and address.

[Illustration: "THE DEMON VANISHED">[

I opened the envelope hoping to find them, but they were not there. The envelope contained merely a finely written manuscript of thirty odd pages, unsigned.

And then I read the story. When I began it was with a half-smile upon my lips, and with a feeling that I was wasting my time. The smile soon faded, however; after reading the first paragraph there was no question of wasted time. The story was a masterpiece. It is needless to say to you that I am not a man of enthusiasms. It is difficult to arouse that emotion in my breast, but upon this occasion I yielded to a force too great for me to resist. I have read the tales of Hoffmann and of Poe, the wondrous romances of De La Motte Fouque, the unfortunately little-known tales of the lamented Fitz-James O'Brien, the weird tales of writers of all tongues have been thoroughly sifted by me in the course of my reading, and I say to you now that in the whole of my life I never read one story, one paragraph, one line, that could approach in vivid delineation, in weirdness of conception, in anything, in any quality which goes to make up the truly great story, that story which came into my hands as I have told you. I read it once and was amazed. I read it a second time and was—tempted. It was mine. The writer himself had authorized me to treat it as if it were my own; had voluntarily sacrificed his own claim to its authorship that he might relieve me of my very pressing embarrassment. Not only this; he had almost intimated that in putting my name to his work I should be doing him a favor. Why not do so, then, I asked myself; and immediately my better self rejected the idea as impossible. How could I put out as my own another man's work and retain my self -respect? I resolved on another and better course—to send you the story in lieu of my own with a full statement of the circumstances under which it had come into my possession, when that demon rose up out of the floor at my side, this time more evil of aspect than before, more commanding in its manner. With a groan I shrank back into the cushions of my chair, and by passing my hands over my eyes tried to obliterate forever the offending sight; but it was useless. The uncanny thing approached me, and as truly as I write sat upon the edge of my couch, where for the first time it addressed me.

"Fool!" it said, "how can you hesitate? Here is your position: you have made a contract which must be filled; you are already behind, and in a hopeless mental state. Even granting that between this and to-morrow morning you could put together the necessary number of words to fill the space allotted to you, what kind of a thing do you think that story would make? It would be a mere raving like that other precious effort of August. The public, if by some odd chance it ever reached them, would think your mind was utterly gone; your reputation would go with that verdict. On the other hand, if you do not have the story ready by to-morrow, your hold on the Idler will be destroyed. They have their announcements printed, and your name and portrait appear among those of the prominent contributors. Do you suppose the editor and publisher will look leniently upon your failure?"

"Considering my past record, yes," I replied. "I have never yet broken a promise to them."

"Which is precisely the reason why they will be severe with you. You, who have been regarded as one of the few men who can do almost any kind of literary work at will—you, of whom it is said that your 'brains are on tap'—will they be lenient with you? Bah! Can't you see that the very fact of your invariable readiness heretofore is going to make your present unreadiness a thing incomprehensible?"

"Then what shall I do?" I asked. "If I can't, I can't, that is all."
