A scene from “Unfinished Business”

Helen Langley: [after Jessica accuses her of committing the murder] It was just past midnight. Ad was drunk. He said he'd been walking up and down the beach, looking for the Indian. He wanted to hit someone, and I was the only one around, so he grabbed me. It was worse than ever. Well, you saw what I looked like this morning. I couldn't hide it. I begged him to stop, but he just kept comin' after me, and so I grabbed the knife on the counter, and I turned around, and I lashed out at him. He staggered. He fell to the floor, and he grabbed one of those chairs as he hit the ground.

Tom Carpenter: That's when she called me. She was out of her mind with fear. I found her on her knees, starin' down at that drunken piece of trash. The knife was still stickin' out of his chest. I mean, what was I gonna do? Let her go to jail for doin' the world a favor? Not my sister, no sir. Then it, you know, just came to me. The trouble at the meetin' hall. I put Ad in my truck, carried him in the side door, and laid him out on the floor. And then, like I figured, that funny-lookin' spear was left over from the meetin', and I picked it up, and I raised it over him.

Jessica Fletcher: And the wound from the lance obscured the real cause of death, the knife wound.

Helen Langley: I can't say I'm sorry he's dead. I know nobody deserves killing, but I just couldn't let him hit me anymore.
