A scene from “Unfinished Business”

Dep. Police Comm. Bradley Folkes: [after Jessica exposes the murderer] For five years, my boy was a good cop. But you can't ask anybody to go through what he did without cracking. Day after day, week after week, living at the edge, part of the whole dirty scene, trying to keep his sanity and do his job. They expected too much of him. It was all so easy. The money, the cars, the women, all there for the taking. And in the end, he just couldn't fight it.

Jessica Fletcher: So he became part of the mess that he was trying to clean up.

Dep. Police Comm. Bradley Folkes: Yeah. And when Eric wouldn't pay, Eddie went to see Lydia Thurlow. In fact, they were arguing about the money when her husband came home. Eddie hid in the next room. Thurlow was drunk and nasty. I guess Lydia must've figured if she'd given Eddie away, her husband would only take it out on her brother, so she didn't say anything. Eddie came to see me next day, scared to death. Swore it had all been an accident. Well, by that time, I knew he'd gone bad, but if Dorothy had learned the truth, it would have killed her. I had a choice to make and I made it. When Bert Kravitz got transferred, I volunteered to take over the case. And it wasn't hard to hang a conviction on Thurlow. He was my son. What was I supposed to do? What are you gonna do?

Jessica Fletcher: Tell the truth.

Dep. Police Comm. Bradley Folkes: To who? Who's going to believe you?

Jessica Fletcher: Maybe Richard Thompson Grant. Maybe no one. I can't help that.

Dep. Police Comm. Bradley Folkes: Mrs. Fletcher, I can't let you do this to my wife. Not after all this time.

Jessica Fletcher: A man has been unjustly imprisoned for sixteen years because of you. Doesn't that count for anything?

Dep. Police Comm. Bradley Folkes: Not enough!
