Isobel Sedbusk: Imagine a substance in daily use everywhere. Anyone can lay his hands on it, and within a minute after taking, the victim's beautifully out of the way. Mind you, it's undetectable after death.
Lina McLaidlaw Aysgarth: Is whatever it is, painful?
Isobel Sedbusk: Oh, not in the least. In fact I should think it'd be a most pleasant death.
Johnnie Aysgarth: Oh, I beg your pardon. Was that your leg? I had no idea we were going into a tunnel. I thought the compartment was empty.
Johnnie Aysgarth: If you're going to kill someone, do it simply.
General McLaidlaw: Good heavens! You can't expect me to remember every detail about everybody, can you?
Johnnie Aysgarth: Well, well. You're the first woman I've ever met who said yes when she meant yes.
Johnnie Aysgarth: You thought I was going to kiss you, didn't you?
Lina McLaidlaw Aysgarth: Weren't you?
Johnnie Aysgarth: Of course not. I was merely reaching around you, trying to fix your hair.
Lina McLaidlaw Aysgarth: What's wrong with my hair?
Johnnie Aysgarth: Well, I'm glad you asked me that. It would've been extremely discourteous for me to bring the subject up.
Johnnie Aysgarth: Your hair's all wrong. It has such wonderful possibilities that I, well, I got excited. For the moment I became a, a passionate hairdresser.
[Lina starts to button her blouse]
Johnnie Aysgarth: Don't do that.
Lina McLaidlaw Aysgarth: Why not?
Johnnie Aysgarth: Because your ucipital mapilary is quite beautiful.
Lina McLaidlaw Aysgarth: I must go now or I'll be late to luncheon. Anyway, if my father saw me come in both late and beautiful, he might have a stroke.
[Johnnie and Lina are facing a large portrait of her father]
Johnnie Aysgarth: He doesn't like me.
Lina McLaidlaw Aysgarth: I know.
Johnnie Aysgarth: He doesn't trust me from here to there. (Speaking to portrait) Do you? Well, you're right. I can only bring her unhappiness. Well, warn her. Speak up, man. It's your last chance. (To Lina) Hear him?
Lina McLaidlaw Aysgarth: Very distinctly.
Johnnie Aysgarth: He's not exaggerating a thing, dear. It's all true, every word he isn't saying.
Lina McLaidlaw Aysgarth: I love him, father.
Johnnie Aysgarth: Did you see him jump?
Lina McLaidlaw Aysgarth: I did.
Johnnie Aysgarth: Well, watch this one. (Speaking to portrait) Sir, I have the honor of asking for your daughter's hand in marriage. Well, what do you say to that? (He begins tapping on the portrait and it falls off the wall) My oh my. You heard him that time, didn't you?
[Lina asks Johnnie how he intends to support them]
Johnnie Aysgarth: Well, if the worst comes to the worst and there's no other way out, I'll have to...
Lina McLaidlaw Aysgarth: What?
Johnnie Aysgarth: Borrow some more.
Lina McLaidlaw Aysgarth: When he enticed his victim across the footbridge, knowing that the bridge has been sawn through...
Isobel Sedbusk: He also knew that his victim couldn't swim. Don't forget that.
Lina McLaidlaw Aysgarth: Well, what I want to know is this. Would you call that an actual murder?
Isobel Sedbusk: Well, from a moral standpoint there's no question at all. It is murder.
Isobel Sedbusk: You couldn't hurt a fly, Bertram, unless it was already dead.
Photographer: I wonder if I could have just a little bit more of your smile?
Johnnie Aysgarth: Oh, now, not at this hour of the morning.
