One night he meets Hallward, who wants to talk to him about his mode of life. The painter enumerates all the scandalous stories he has heard about him; he ends up by expressing a doubt whether he really knows his friend. To do so, he says, he should have to see his soul. "You shall see it yourself to-night," Dorian exclaims, "it is your handiwork," and, holding a lamp, he takes him up to the locked room, and removes the drapery from the picture. An exclamation of horror breaks from the painter as he perceives the hideous face on the canvas grinning at him. It fills him with loathing and disgust, and he has difficulty in believing it to be his own work. Dorian is seized with an uncontrollable feeling of hatred for his friend, and, seizing a knife lying on a chest, stabs him in the neck and kills him. After the murder he locks the door, and goes quietly downstairs. He slips out into the street closing the front door very gently, and rings the bell. When his valet opens it he explains that he had left his latchkey indoors, and casually inquires the time, which the man informs him is ten minutes past two. The next day Dorian sends for a former friend of his, Alan Campbell, whose hobby is chemistry, and after telling him of the murder, begs him by some chemical process to destroy the body. Alan refuses to help him. Dorian then writes something upon a piece of paper and gives it to the other to read. Alan is terror-struck and consents to do what is required of him, though reluctantly. When later, provided with the necessary chemicals, they enter the locked room, Dorian perceives that the hands of the picture are stained with blood. He dines out that night, and when he returns home he provides himself with some opium paste he keeps locked up in a secret drawer, and having dressed himself in rough garments makes his way to the docks. He enters an opium den, but the presence of a man who owes his downfall to him irritates him, and he decides to go to another. A woman greets him with the title "Prince Charming" (the name Sybil had given him), and on hearing it a sailor gets up from his seat and follows him. In a dim archway he feels himself seized by the throat and sees a revolver pointed at his head. Briefly, his assailant tells him that he is Sybil's brother, and that he means to avenge his sister's death. A sudden inspiration comes to Dorian and he inquires of the man how long it is since his sister died. "Eighteen years," is the answer, and Gray triumphantly exclaims "Look at my face." He is dragged under a lamp, and at sight of the youthful face Sybil's brother is convinced that he has made a mistake. Hardly has Dorian gone, when the woman who had called him Prince Charming comes up, and from her the sailor learns that in eighteen years Dorian has not altered.
