A scene from “Unfinished Business”

Jon Vandervelt: [after Jessica exposes him as the murderer] I had designed Netherlander. I loved her. I planned on racing her for Holland in the next World Cup. Nothing could have beaten her. Then I saw that he had applied for a patent on her. And at the Ball, Admiral Spalding said that he had talked about her as his own trimaran. I knew I had to settle things with Mr. Kimball. When I realized he was dead, it occurred to me that there might be a way out. I knew Anne Larkin had been there. I read the custody papers that Mr. Kimball was putting away. They already had his blood on them, so I placed them in Anne Larkin's bedroom, where you found them. But the killing itself was unpremeditated, a moment of rage.

Jessica Fletcher: Was it? You didn't go through the gate when you went to see Mr. Kimball. You made sure that you got into his office unobserved, didn't you?

Jon Vandervelt: Well, let's say I went prepared to do whatever was necessary.
