Sam Spade: I hope they don't hang you, precious, by that sweet neck. Yes, angel, I'm gonna send you over. The chances are you'll get off with life. That means if you're a good girl, you'll be out in 20 years. I'll be waiting for you. If they hang you, I'll always remember you.

Sam Spade: Now, both you and the police have as much as accused me of being mixed up in the other night's murders. Well, I've had trouble with both of you before. And as far as I can see my best chance of clearing myself of the trouble you're trying to make for me, is by bringing in the murderers all tied up. And the only chance I've got of catching them, and tying them up, and bringing them in, is by staying as far away as possible from you and the police, because you'd only gum up the works.

Sam Spade: Now, let's *talk* about the black bird.
Kasper Gutman: Let's. Mr. Spade, have you any conception of how much money can be got for that black bird?
Sam Spade: No.
Kasper Gutman: Well, sir, if I told you... If I told you *half*... you'd call me a liar.
Sam Spade: No, not even if I thought so.

Sam Spade: All we've got is that maybe you love me and maybe I love you.
Brigid O'Shaughnessy: You know whether you love me or not.
Sam Spade: Maybe I do. I'll have some rotten nights after I've sent you over, but that'll pass.

Sam Spade: I don't mind a reasonable amount of trouble.

Sam Spade: I hope you're not letting yourself be influenced by the guns these pocket-edition desperadoes are waving around, because I've practiced taking guns from these boys before; so we'll have no trouble there.

Sam Spade: If you kill me, how are you gonna get the bird? And if I know you can't afford to kill me, how are you gonna scare me into giving it to you?

Sam Spade: We didn't exactly believe your story, Miss O'Shaughnessy. We believed your 200 dollars. I mean, you paid us more than if you had been telling us the truth, and enough more to make it all right.

Sam Spade: When a man's partner is killed, he's supposed to do something about it. It doesn't make any difference what you thought of him. He was your partner and you're supposed to do something about it. And it happens we're in the detective business. Well, when one of your organization gets killed, it's-it's bad business to let the killer get away with it, bad all around, bad for every detective everywhere.

Sam Spade: When you're slapped, you'll take it and like it.
