Dorian's arms fell to his side. Paralysed with terror, he did not know what to do. Suddenly a wild hope flashed across his brain. "Stop," he cried. "How long ago is it since your sister died? Quick, tell me!"

"Eighteen years," said the man. "Why do you ask me? What do years matter?"

"Eighteen years," laughed Dorian Gray, with a touch of triumph in his voice. "Eighteen years! Set me under the lamp and look at my face!"

James Vane hesitated for a moment, not understanding what was meant. Then he seized Dorian Gray and dragged him from the archway.

Dim and wavering as was the wind-blown light, yet it served to show him the hideous error, as it seemed, into which he had fallen, for the face of the man he had sought to kill had all the bloom of boyhood, all the unstained purity of youth. He seemed little more than a lad of twenty summers, hardly older, if older indeed at all, than his sister had been when they had parted so many years ago. It was obvious that this was not the man who had destroyed her life.

He loosened his hold and reeled back. "My God! my God!" he cried, "and I would have murdered you!"

Dorian Gray drew a long breath. "You have been on the brink of committing a terrible crime, my man," he said, looking at him sternly. "Let this be a warning to you not to take vengeance into your own hands."

"Forgive me, sir," muttered James Vane. "I was deceived. A chance word I heard in that damned den set me on the wrong track."

"You had better go home and put that pistol away, or you may get into trouble," said Dorian, turning on his heel and going slowly down the street.

James Vane stood on the pavement in horror. He was trembling from head to foot. After a little while, a black shadow that had been creeping along the dripping wall moved out into the light and came close to him with stealthy footsteps. He felt a hand laid on his arm and looked round with a start. It was one of the women who had been drinking at the bar.

"Why didn't you kill him?" she hissed out, putting haggard face quite close to his. "I knew you were following him when you rushed out from Daly's. You fool! You should have killed him. He has lots of money, and he's as bad as bad."

"He is not the man I am looking for," he answered, "and I want no man's money. I want a man's life. The man whose life I want must be nearly forty now. This one is little more than a boy. Thank God, I have not got his blood upon my hands."
