Colin Graves lives a normal middle-class life until he finds a story outline at his friend Taylor Knight’s apartment entitled, With Three You Get Murder. The three main characters are oddly similar to himself, his wife, Maddy, and Taylor. The wife and friend have the customary affair, and the husband finds a home six feet under. Writers often use people they knew as the basis for story characters. Of course it was nothing more. But bit by bit Colin notices things that spark his suspicions. Enter Max Madden, a private detective, who unearths some “interesting facts:” Maddy was married before, had an affair with her husband’s best friend, and her husband died of an apparent suicide. Max thinks the suicide is suspicious, and says he believes Maddy did it. Convinced of his wife’s infidelity and best friend’s betrayal, Colin devises a scheme to murder Taylor and frame Maddy, using the information he’d received from the detective to set it up. But when it comes down to it, Colin can’t pull the trigger. He isn’t capable of killing anyone, let alone his best friend. Several days later the doorbell rings. It’s the police. They want to question Colin about Taylor’s murder. The glint in Maddy’s eye tells him she got him. She’d found out about his plan, finished the job, and framed him. No wonder she was in such a good mood.
