Alan Campbell was once a very good friend of Dorian’s. They had met at a party. Alan was a chemist but he played the piano very well, and his interest in music attracted Dorian. They went to the opera together and Alan thought, like many others, that Dorian was a wonderful man who always did exciting things. Then, one day, they stopped seeing each other. No one knew why, but they noticed that Alan always left the room when Dorian entered. Alan became sad and depressed. He stopped playing music and going to parties, and he spent most of his time alone in his laboratory doing experiments.
Dorian Gray looked at the picture. Suddenly he felt that he hated Basil Hallward. He hated the man sitting at the table more than he hated anything in his life.
A flash of hatred ran through Dorian’s body. He looked at the picture and it was as if the picture told him what to do.
He looked wildly around. Something shone on top of the painted cupboard that faced him. His eye fell on it. He knew what it was. It was a knife that he had brought up, some days before, to cut a piece of cord, and had forgotten to take away with him. He moved slowly towards it, passing Hallward as he did so. He took the knife in his hand and turned around. Hallward moved in his chair. He rushed at him, and stuck the knife into his neck again and again
Dorian had been happy for many years. He had enjoyed his life. He had not cared about other people. Dorian had done the things Harry had told him to do.
