- [hitman enters the room of the bar owner]
- Martey, Nightclub Owner: Who are you?
- Jeff Costello: Doesn't matter.
- Martey, Nightclub Owner: What do you want?
- Jeff Costello: To kill you.
- [shoots him]
- Gunman: Nothing to say?
- Jeff Costello: Not with a gun on me.
- Gunman: Is that a principle?
- Jeff Costello: A habit.
- Jeff Costello: Who sent you?
- Gunman: I can't tell you that.
- Jeff Costello: Yet you could try to kill me. Look at me. I'll ask you just once more. Who? Name and address.
- Gunman: You don't know him; he's not in our league.
- Jeff Costello: Don't keep me waiting.
- Gunman: Olivier Rey... 73, Boulevard de Montmorency.
- Jeff Costello: That's how you became unemployed.
- [pulls a gun on her, she just looks disappointed]
- Valérie: Why Jeff?
- Jeff Costello: I've been paid to.
- Jeff Costello: Why did you say you didn't recognize me?
- Valérie: Why did you kill Martey?
- Jeff Costello: I was told I'd be paid.
- Valérie: What did he do to you?
- Jeff Costello: Nothing at all. I didn't even know him. The first and last time I saw him was 24 hours ago.
- [pause]
- Valérie: What sort of man are you?
- Olivier Rey's associate: He's a lone wolf.
- Olivier Rey: He's a wounded wolf; now there will be a trail. He must be disposed of quickly.
- Superintendant: Don't you love him?
- Jane Lagrange: No.
- Superintendant: Really? I'd have said you did. Laying yourself on the line for him like that, I thought you must love him.
- Jane Lagrange: You're not the psychologist you imagined.
- Jane Lagrange: If I understand you right, I'll have no problems if I perjure myself. If I insist on telling the truth, then I can expect trouble. Am I right?
- Superintendant: Not quite. Because the truth isn't what you say, it's what I say... despite the methods I am obliged to employ to get at it.
- Superintendant: I don't like forcing the pace to extract confessions or get information. I'm very liberal, a great believer in the liberty of the individual... in people's right to live as they choose. Provided that the way of life they choose harms no one else... and is contrary to neither law and order nor public decency.
- Bushido (Book of the Samurai): There is no greater solitude than that of the samurai, unless it is that of the tiger in the jungle... perhaps...
- Superintendant: It's strange. Girls like you are virtually prostitutes. Ever give it any thought?
- Jane Lagrange: [sitting on her bed in a nightgown while her apartment is being searched by the police] No.
- Superintendant: You should. It could blow up in your face. If the vice squad starts in after you - those boys mean business. You need to be covered. No pun intended.
- Jane Lagrange: And you want to cover me?
- Superintendant: Let's suppose Costello wasn't here during those six hours and I find out. You'll be indicted for perjury, contempt of court, obstruction of justice, and accessory to murder. You'll get at least five years. Five years is a long time. Especially for a girl your age.
- Superintendant: Little Jef Costello will be sitting in this chair.
- Superintendant's Assistant: He'll just laugh in our faces.
- Superintendant: I doubt it. Ever see a guy stay handcuffed for 48 hours and not open his mouth? I haven't seen many.
- Superintendant: You arrived at Miss Lagrange's apartment at 2:00 or 2:15am?
- Wiener: Yes. That's right.
- Superintendant: Think carefully before you answer. Did you have the feeling upon entering her apartment that someone had just left? Forgive me for being so blunt, but didn't you feel your spot was still warm?
