The Postman Always Rings Twice1946

Frank:
We've been double-crossed, Cora. That lawyer Keats, he's nothing but a police stool pigeon.

Cora:
I've been double-crossed, not you. Oh I see it all, now. I see why I had to drive the car, not you. And that other time, why it was me that had to do it and not you.

Frank:
That's not so.

Cora:
Oh yes it is. I used to think to myself the reason I fell for you was because you were smart. Now I find out that you are smart. Double-crossed, hah! I'll say I was. You and that Keats fixed it up so that I tried to kill you too. That was to get you clear. And then you two fixed it up to plead me guilty. Well, listen, Mr. Frank Chambers. When I get through, you'll find out there's such a thing as being too smart.
