A scene from “Unfinished Business”

Iris Novaro: [after Jessica exposes her as the murderer] You know, that's the one thing I didn't figure on. Dave never stopped loving Janet. I think that's what ticked me off so much that night when I stopped by the store to tell him I didn't want a divorce after all. Someone was just running out of the store.

Jessica Fletcher: That would've been Norman Trent. According to his statement, he went there to avenge his daughter but was having second thoughts.

Iris Novaro: Well, he was in such a hurry to get out, he dropped his cane. That was Dave's misfortune. He stormed out of his office, saying he had read your book, and it reminded him of how he'd given me the damn garage opener to get fixed, and that was the way I got back into the house. And the fact is, it was all true. It made me angry. I forgot why I was there because he was gonna call the police. That's when I hit him with the cane. I cleaned my prints off it and threw it in the dumpster down the street. After all these years, no way was I gonna go to jail.

Lt. Artie Gelber: You wanna bet?
