Conceive of the situation if you can. Imagine the horror of it, and then ask yourself if it was likely that when next morning came I could by any possibility bring myself to my work-table in fit condition to prepare for you anything at all worthy of publication in the _Idler._ I tried. I implore you to believe that I did not hold lightly the responsibilities of the commission you had intrusted to my hands. You must know that if any of your writers has a full appreciation of the difficulties which are strewn along the path of an editor, _I_, who have myself had an editorial experience, have it, and so would not, in the nature of things, do anything to add to your troubles. You cannot but believe that I have made an honest effort to fulfil my promise to you. But it was useless, and for a week after that visitation was it useless for me to attempt the work. At the end of the week I felt better, and again I started in, and the story developed satisfactorily until--_it_ came again. That figure which was my own figure, that face which was the evil counterpart of my own countenance, again rose up before me, and once more was I plunged into hopelessness. Thus matters went on until the 14th day of October, when I received your peremptory message that the story must be forthcoming the following day. Needless to tell you that it was not forthcoming; but what I must tell you, since you do not know it, is that on the evening of the 15th day of October a strange thing happened to me, and in the narration of that incident, which I almost despair of your believing, lies my explanation of the discovery of October 16th, which has placed my position with you in peril. At half-past seven o'clock on the evening of October 15th I was sitting in my library trying to write. I was alone. My wife and children had gone away on a visit to Massachusetts for a week. I had just finished my cigar, and had taken my pen in hand, when my front -door bell rang. Our maid, who is usually prompt in answering summonses of this nature, apparently did not hear the bell, for she did not respond to its clanging. Again the bell rang, and still did it remain unanswered, until finally, at the third ringing, I went to the door myself. On opening it I saw standing before me a man of, I should say, fifty odd years of age, tall, slender, pale-faced, and clad in sombre black. He was entirely unknown to me. I had never seen him before, but he had about him such an air of pleasantness and wholesomeness that I instinctively felt glad to see him, without knowing why or whence he had come. "Does Mr. Thurlow live here?" he asked. You must excuse me for going into what may seem to you to be petty details, but by a perfectly circumstantial account of all that happened that evening alone can I hope to give a semblance of truth to my story, and that it must be truthful I realize as painfully as you do. "I am Mr. Thurlow," I replied.
