A scene from “Unfinished Business”

Eliot Easterbrook: [after Jessica exposes him as the murderer] Even the finest works of art have their flaws. Congratulations, Mrs. Fletcher. The only thing missing is a motive.

Jessica Fletcher: Yes, I wondered about that.

Eliot Easterbrook: Imagine a young and impressionable writer who has his first play produced off-off-off Broadway. It's not perfect, but he has talent, and it's a start. And imagine a critic from a second-rate newspaper trying to make a name for himself. His review of the play is devastating. So devastating the young playwright never writes another play. No, instead, he becomes a critic himself and vows to best his destroyer at his own game. But it's not enough. It's not enough to eradicate the pain. Only one thing can do that.
