"I closed my eyes. The fatigue wrapped me more closely. Sleep at last was surely drawing near. But suddenly I knew--how I cannot exactly say--that once more the shutter was to be drawn back for me. This knowledge resembled a horrible physical sensation. The entry of it into my mind, or indeed into my very soul, was as the dawning of a dreadful and unnatural pain in the body. This pain increased till it became agony. Although I still lay motionless, I felt like one involved in a furious struggle in which the whole sum of me took violent part. And there came to me the simile of a man seized by tremendous hands, and held before a window opening into a room in which something frightful was about to take place. And the shutter slipped back from the window. "Again I looked upon myself. That was my exact sensation. The shutter drawn back, I assisted at the spectacle of Marcus Harding's life.

I left him smiling thus, reached my house, and stood before it. "Now I must tell you, and I rely absolutely on your regarding this as said in the strictest, most inviolable confidence--" "Certainly. Word of honor, and so forth!" said the professor, quickly and sharply. "I must tell you that Marcus Harding is a sinner, and not merely in the sense in which all men are sinners. There have been recurring moments in his life when he has committed actions which, if publicly known, would ruin him in the eyes of the world and put an end to his career. As I looked at myself standing before my house, I saw that I was hesitating whether to go in with my misery, or whether to seek for it the hideous alleviation of my beloved sin.
