Consider this: classic noir movies are about truth rather than erotic satisfaction. A MacGuffin pulls a narrative down a track criss-crossing the love story that will make the movie end happily. We want the happy ending, but not too soon.
I love this moment in China Miéville's The City & the City: The narrator (for this is an I-book), Inspector Tyador Borlu, is a noir cop in a fictional Balkan capital, Corwi is his assistant, and in their language aj Tyrko means Turkish-style.
