The green-stained napkin (SPOILERS)
Great movie! It works out just like a big and perfect clock: one of the best film noir I've ever seen. But i just have one question for you I cannot answer. At the end of the film Hagen gets in trouble and discovered by Stroud as he pulls out from the wooden cigarette box stroud's napkin with the mint stain on it.
Why this should be such a great evidence? I mean: anyone can paint a napkin green or get it dirty with mint, I don't think it is something that can prove your guiltiness.That could even be another different napkin, and not necessarily THAT napkin they're looking for! Did i miss something? What do you think?
Thank you!
