How we cite our quotes: All quotations are from The Maltese Falcon.
Quote #4
SPADE: I don't care what your secrets are. But I can't go ahead without more confidence in you than I've got now. You've got to convince me that you know what this is all about, that you aren't just fiddling around hoping it'll all come out right in the end.
BRIGID: Can't you trust me a little longer?
SPADE: How much is a little? What are you waiting for?
Loyalty and trust are like credit in a way. Brigid keeps asking for loans that Spade is tired of giving. He needs a little bit of moral collateral if he's going to keep trusting her.
Quote #5
SPADE: I don't know where the bird is. Neither do you. She does. How'll we get it if I don't play along?
Spade plays Cairo by trying to convince him that he's playing Brigid, but he does it with such a straight face it's hard to tell if he's just pretending to sell her out or if he'd actually do it. Maybe he's pulling one over on all of them.
