- John Marlowe: You should've ordered him out of the house.
- Margaret Manderson: And confirm his suspicions?

- Burton Cupples: You know, I've always noticed since you were a little girl that when you're worried you turn to music and when you're very worried you turn to Mozart.
- John Marlowe: One fact, one horrifying fact was suddenly clear to me. Manderson was insane. He was gloating over me, driving away to my fate, but what fate?
- Burton Cupples: Oh Philip. If you'd care to wipe the name of Manderson off the family slate, you'd be doing all of us a good turn. Trent's such a much nicer name, don't you think so Margaret?
