- Yancey Derringer: I wouldn't stand to close to me tonight. I'm strictly hard luck - it might rub off.
- Captain Amos Fry: It already has.
- Yancey Derringer: Are you losing, too?
- Captain Amos Fry: No, I have orders to place you under arrest.
- Captain Amos Fry: He's in here, sir. Solitary confinement.
- John Colton: Solitary?
- Senator Tyson Yardley: Mr. Colton, the prisoner is being held incommunicado. He will see no one.
- John Colton: Except myself.
- Senator Tyson Yardley: Including yourself, Mr. Colton. He shall see no one except his defense counsel.
- John Colton: And that man, Senator, will be me! Open up.
- Yancey Derringer: Mr. Colton, come on in, sit down. There isn't much of a view, but the rats are friendly.
- John Colton: The gun that murdered Lincoln...
- Yancey Derringer: ...was a .44 calibre single-shot muzzle loading deringer made in Philadelphia, Pennsylvania. It's spelled with one "R" - my name is spelled with two. No relation.
- John Colton: Did you ever own such a gun?
- Yancey Derringer: Yes, two.
- John Colton: I see. You'd better tell me about it.
- Yancey Derringer: It was a present from my daddy before the war. It was a birthday present. He sent to Philadelphia for them. He said that no well-dressed poker player could fill a flush without them.
- Yancey Derringer: I was in and out of Southern Maryland from '63 on, the same time that Booth was there.
- John Colton: Then Yardley has a beautiful circumstantial case against you.
- Yancey Derringer: It's true, but I have one thing in my favor.
- John Colton: What?
- Yancey Derringer: You.
- Senator Tyson Yardley: You are aware that the prisoner attempted to escape last night?
- John Colton: You mean someone attempted to murder the prisoner last night. To prevent his appearance at the trial, do you think, Senator?
- John Colton: [to Pahoo] No matter what happens, don't try to help Yancy.
- Madame Francine: No use telling him that, Mr. Colton. If you can't save Yancy, Pahoo will try.
- John Colton: Madame Francine, I'm afraid he would die trying.
- Obadiah: I don't think that would bother him, Mr. Colton.
- Madame Francine: Is there any more trouble you can get into?
- Yancey Derringer: Francine, from now on, it's trouble I want to get out of, believe me.
- Madame Francine: I wouldn't believe you if you swore on a poker deck.
- [last lines]
- John Colton: But how did you know?
- Yancey Derringer: His voice.
- John Colton: Just that?
- Yancey Derringer: Mr. Colton, when you're behind enemy lines meeting a spy in the dark, one thing that you never forget is his voice.
- John Colton: I don't think he'll forget yours, either.
- Madame Francine: Gentlemen, the drinks are on me.
- John Colton: Captain Fry, get that man to a hospital - a military hospital.
