A scene from “Unfinished Business”

Jessica Fletcher: [after deducing the murderer's identity] You weren't in a trance just now, and you weren't in a trance last night. You cleverly discovered how to outwit Cagliostro's most powerful tool: his voice. You put earplugs in your ears before you came up to the room. In effect, you became temporarily deaf. That's why you didn't respond when I called to you in the lobby. Because you couldn't hear me. Upstairs in the room, you pretended to be in a trance like the others. Then you surprised Cagliostro and stabbed him to death with a steak knife from the restaurant.

Andrew Townsend: No wonder you're a writer. You've got one hell of an imagination.

Jessica Fletcher: Lieutenant Bergkamp confirmed that you bought your earplugs in the gift shop. And your reference to the elevator as a lift suggested that you had spent some time in England. And I'm sure that some digging around will turn up a connection with Cagliostro.

Andrew Townsend: I'll save you the trouble. My father was Bud Michaels's bureau chief, and as such, he okayed the article that Cagliostro tricked Michaels into writing. So when Cagliostro sued Michaels, my father was named too. And when Michaels's career was destroyed, my father's was destroyed along with it. He just couldn't face starting over again, so he killed himself. I wanted to get Cagliostro for years, but I just could never figure out how. But when this thing dropped into my lap, the whole plan came to me just like that.
