A scene from “Unfinished Business”

Kevin Cauldwell: [after Jessica exposes him as the murderer] In those days, Bill was my boy, the son I never had. He was roaring drunk prom night. Too drunk to drive home.

Jessica Fletcher: So you put him in your car.

Kevin Cauldwell: And we had the bad luck to come upon that man in the Corvette. Bill kept grabbing the wheel, trying to get me to turn around and take him to that diner where his friends were. Just then, the Corvette came round the bend, and Bill jerked the wheel over hard. I was worried the driver might be injured. Bill was scared and wanted to get outta there fast. He was too drunk to think straight. I swung around and went back. The door was open on the passenger side. I thought the crash sprang it open. The driver was unconscious and bleeding. Then I saw the bearer bonds scattered all over the floor from an open valise. Good as cash. The driver came to and saw me holding the bonds. That's when I panicked, Jessie. The sight of all that money just there for the taking. I didn't even think about it. I just picked up a rock, and I hit him again and again! I hadn't planned it, Jessie. But the man was dead. There were all those bonds and done was done.

Jessica Fletcher: Yes, but what about Bill?

Kevin Cauldwell: The boy idolized me. Would have done anything for me, and he did.

Jessica Fletcher: And once Bill sobered up, you swore him to secrecy in return for half the bonds.

Kevin Cauldwell: That's right, Jessie. We sat on those bonds for a couple of years and then cashed them in.

Jessica Fletcher: And allowed Andrew Durbin to spend twenty years in prison for a crime that you committed.

Kevin Cauldwell: I know, I know. It was a terrible thing. But I've lived with that secret for twenty years, Jessie. Do you understand? I guess I should've known that nothing good would've come of that money.
