- [Peter demonstrates a throat-cutting on Bunter, then sees Harriet's shock]
- Lord Peter Wimsey: I'm so sorry.
- Harriet Vane: No, no, it's all right.
- Lord Peter Wimsey: No, no, I'm an ass. And in a moment I shall get down on my knees and apologize, and probably propose to you as well.
- Harriet Vane: Oh, Peter! What an idiot you are!
- Lord Peter Wimsey: Aren't I, though?
- Salcombe Hardy: You wouldn't be here for the suicide of a foreign gigolo. There's something more to it than that... unless it's just the girl? Oh, for God's sake, Wimsey, say it isn't the girl! You wouldn't play a joke like that on a hard-working journalist. Look, how about you give me a story about you and Harriet Vane? "Romantic Engagement of Peer's Son and Crime Novelist!"
- Lord Peter Wimsey: Pull yourself together, Sally, and keep your inky paws off my private affairs.
- Harriet Vane: I'm afraid I'm not a very good dancer.
- Antoine: You dance very correctly, Mademoiselle. It is only the entrain that is a little lacking. It is possible you are awaiting the perfect partner. When the heart dances with the feet it will be à merveille.
- [while Peter is dancing with Harriet]
- Antoine: [over his partner's shoulder] Qu'est-ce que je vous dit, Mademoiselle? L'élan, c'est trouvé.
- Lord Peter Wimsey: What did that blighter say?
- Harriet Vane: Something about how I dance better with you than I did with him.
- Lord Peter Wimsey: What infernal cheek!
