Quote #10
THORWALD: Can you get me that ring back?
JEFF: No.
THORWALD: Tell her to bring it back!
JEFF: I can't. The police have it by now.
Jeff may be being a little too clever here. There's no reason for Thorwald to leave him alive since Jeff has procured the evidence he needs. By now, Thorwald is flipping out and loses his ability to think clearly. He should have known that by tossing Jeff out the window, the cops would be all over him. But maybe he's realized that he's been found out, and the best thing to do is to kill the guy who figured it out.
