Harriet Vane: If anybody does marry you, Peter, it will be for the pleasure of hearing you talk piffle.
Harriet Vane: Peter, people have been wrongly condemned before now.
Lord Peter Wimsey: Only because I wasn't there.
Harriet Vane: Oh, I never thought of that.
Bill Rumm: We all are like sheep who have gone astray, and well I may say so, for I was a dark and wicked sinner myself, until this here gentleman laid his hand upon me as I was a-bustin' of his safe, and became God's instrument for turning me away from the path that leadeth to destruction.
Lord Peter Wimsey: I don't suppose you have the faintest idea how to pick a lock, Miss Murchison?
Miss Murchison: [Clearly shocked at the question] I'm... afraid... not - no idea whatsoever!
Lord Peter Wimsey: [Shaking his head ruefully] I sometimes wonder what we went to school for.
Harriet Vane: [as Peter walks in for a prison visitation] Can't help being a gentleman, can you?
Lord Peter Wimsey: Afraid not... drilled in when I was too young to resist.
Harriet Vane: You are bearing in mind, aren't you, that I've had a lover?
Lord Peter Wimsey: Oh, yes, so've I. Several, in fact. It's the sort of thing that could happen to anyone. I can produce quite good testimonials. I'm told I make love rather nicely. Though I am at a bit of a disadvantage at the moment. One can't be too convincing at the other end of the table with a bloke looking in the window.
Harriet Vane: I'll take your word for it.
Sylvia Marriott: Sugar?
Lord Peter Wimsey: No, thanks.
Sylvia Marriott: I thought all men liked to make their coffee with syrup.
Lord Peter Wimsey: I'm rather unusual. Haven't you noticed?
Sylvia Marriott: I've not had time to observe you, but I'll take the coffee as a point in your favor.
Chief Inspector Parker: [Reprovingly] Your vision is clouded because of her - Harriet Vane! Peter, can you tell me in all honesty that you're not allowing your judgement to be affected by your emotions?
Lord Peter Wimsey: Yes, I can.
