Melissa (1974)

Unemployed journalist and aspiring novelist Guy Foster has a minor argument with his wife Melissa and decides to stay home while she attends a party with friends. Later that night, Melissa phones and asks him to join her. Out driving, he comes across the police surrounding a crime scene. A woman has been strangled --it's Melissa. With each twist and turn, Guy is further incriminated: mysterious phone calls, a second dead body, and a psychiatrist who treated Guy for his anger-management problems but he doesn't remember seeing. Guy is desperate to solve the case, but nobody and nothing is what it seems.
