Quote from Daphne in Retirement is Murder
Niles: Who is this menacing little mono-brow? Daphne: Oh, that's Robitaille, a logger. An ex-boyfriend of Helen's. He used to come down from the mountains every couple of months and disappear with her. Niles: If you ask me, he's the murderer. Daphne: Impossible. He's got an air-tight alibi. Niles: What is it? Daphne: He was killing somebody else at the time.
