Quote from Blanche in The Truth Will Out
Blanche: Well, whoever said a man is innocent until proven guilty sure said a mouthful. I was wrong about Duncan, he didn't kill Tippi! Dorothy: Well, what about all that evidence? The scuba gear, the carpet, the dickey? Blanche: It turns out it was one of their trusted servants who was trying to frame poor Duncan. Dorothy: Oh, don't tell me. The butler did it? Blanche: No, he just thought of it. He made the maid do it.
