ok there were two story lines the first was the artist one. It was the artists publicist, can not remember his name. He persuaded the artist to kill himself telling him no one would forget him and his work if he did this.
The second story line was the one with the woman Harry went out with. She was not having an affair. The guy she was with, and who kept phoning the step father , was her son. The step father was the guy dad, not Harry. The guy had been put up for adoption. The woman who died was given an overdose by her mother,she went to visit her to say she wanted the son to be given some money . The mother was jealous that the woman had had an affair and had a baby with her husband. She was also concerned that the fact would come out. She crushed up anti depressant s and put then in the daughters drink. The daughter then got in her car, fell asleep at the wheel and crashed killing herself. The son phoned the father and told him he was coming to see him but the father was not in so he left a message the machin. His grand mother got the message and was waiting for him and shot him " stone dead."
I hope you can understand the message.
