District Attorney Markham
- Philo Vance: Say, Markham, I just heard about Arthur Coe.
- Dist. Atty. Markham: Yes. Too bad he had to bump himself off like that.
- Philo Vance: Hmm, that's why I called you. You sure that he did bump himself off?
- Dist. Atty. Markham: Well, his butler tells us he's sitting in a locked room with a revolver in his hand and a bullet in his head. I don't know what else you'd call it.
- Philo Vance: Well, if you knew Archer Coe, you would know that suicide would be almost a psychological impossibility for him.
- Dist. Atty. Markham: Psychological, bosh! Now two and two make four, don't they?
- Philo Vance: How do you know you have two and two?
- Dist. Atty. Markham: Haven't you got any ideas, Vance?
- Philo Vance: Markham, it's a maze of conflicting clues. Any one of seven people might have done it.
- Detective Sgt. Heath: We couldn't convict seven people, Mr. Vance.
- Philo Vance: You couldn't convict one with the evidence you've got.
