- Prof. Karl Meister: Good heavens, Paul. What's happened to you?
- Paul Heitz: Oh, why I've um, I've been ill.
- Prof. Karl Meister: Ill? You must have been in your grave and dug your way out.
- Professor Jules Heitz: I want to ask you a simple question.
- Dr. Namaroff: Pleas...
- Professor Jules Heitz: You were once a guest in my house in Berlin. You met both my sons - Bruno. in particular. You talked to him at some length.
- Dr. Namaroff: I believe I did.
- Professor Jules Heitz: What impression did you form of him?
- Dr. Namaroff: Well, I thought he was...
- [Pausing to light a match]
- Professor Jules Heitz: Normal?
- Dr. Namaroff: Why, yes, of course.
- Professor Jules Heitz: Yet capable of murder?
- Dr. Namaroff: My dear Heitz, that is hardly a fair question. Given a certain set of circumstances, I believe almost everyone is capable of murder.
- Prof. Karl Meister: [Contemptuously to Inspector Kanof] Don't use long words, Inspector; they don't suit you.
- Dr. Namaroff: We are men of science. I don't believe in ghosts or evil spirits, and I don't think you do, either.
- Professor Jules Heitz: That's one of the most unscientific remarks I have ever heard. I believe in the existence of everything which the human brain is unable to disprove.
- Prof. Karl Meister: Well, I hadn't seen you for some considerable time, so I thought I'd come see what you're doing.
- Paul Heitz: It's a long story.
- Prof. Karl Meister: I've come a long way to hear it.
- Dr. Namaroff: [Seeing Carla's reaction to his dissecting of a brain] It isn't a pretty sight. Never ceases to amaze me why the most noble word of God, the human brain, is the most revolting to the human eye.
- Coroner: [At the inquisition of Bruno Heitz] From the evidence I've heard, I have the impression that your son was somewhat of a bohemian. Would you agree with that?
- Professor Jules Heitz: He was a talented artist. His life was of his own choosing.
- Coroner: I also had the impression he was a libertine.
- Professor Jules Heitz: [emphatically] No!
- Coroner: He had a number of girlfriends?
- Professor Jules Heitz: Possibly. However, that does not make him a libertine.
- Prof. Karl Meister: Incidentally I understand that some of your democratic citizens tried to eject the late professor Heitz. You better warn them not to attempt that sort of behaviour with me.
