A scene from “Unfinished Business”

Devon Lane: [after Jessica reveals how the murder was committed] All right. I took the gun out of the closet. But I didn't set it up. His loving wife did that.

Sheriff Beals: Why did she put the shotgun in her closet and not his?

Jessica Fletcher: Because Walter might have opened his closet any time. She wanted it to happen during the period when they both had their carefully planned alibis, so she set it up in her closet. When she called him from my apartment, she must have asked him to get something for her.

Devon Lane: A credit card she said she left in the pocket of a jacket.

Joanna Rollins: No. This whole sick plan was his idea! He said he'd be a decoy so no one would suspect me! Really! He's mentally deranged! He's violently ill! I've taken the abuse. I've taken it day after day and month after month. But he said to me ... He said if I didn't cooperate, he'd kill me! And I knew he would; I did! I knew he would! I knew it.

Devon Lane: Bravo, darling. How about trying it again? Only this time, with conviction.
