So, I have a noir story and my leads, an assassin and an escaped con (the former saved the latter and helped him to hide from police) should do some "job" together which would allow them to leave the city and go to somewhere they'd be safe. What could they rob? Mind they're no petty thieves. They need something big, suitable for gentlemen, and not 100% crazy. It could work if it weren't for the old, cunning inspector, some traitors and the laws of the genre, which clearly say they won't make it to the ship/train/plane.
