A scene from “Unfinished Business”

Judith Harlan: [after Jessica exposes her as the murderer] Patricia's appointment was not with her hairdresser. It was with me. I went out there to confront her privately with what my investigator had turned up. I offered her a handsome settlement to divorce Jim quietly, without scandal. But Patricia was not only greedy, she was arrogant, and she became very abusive. She had the audacity to hit me. I grasped for whatever was near me. It was the poker in the fireplace. And I struck her down.

Annette Pirage: So you were the one who disconnected the gas line in the basement?

Judith Harlan: It wasn't difficult. I calculated I had enough time to get back to the city before the fire consumed her.

Jessica Fletcher: And you couldn't bear to see your mother's brooch destroyed, so you removed it from the body.

Judith Harlan: I hope you realize that I never would have let Jim be convicted for something I had done.
