/lit/ - Literature

Where do you get your ideas for scenes /lit/?
It's easy for me to type up an outline of a story I'd like to take a protagonist through but filling it up with random scenes quickly becomes the issue.
Like I know I want murder to happen. I want the protagonist to meet or be interviewed by the police. But then I want them to flee.
I don't want them to resist arrest or try to break out of handcuffs/jail/prison.
It's the scene of somehow making brief contact with the police then becoming a fugitive that leaves me puzzled.
Expanding on that idea, as they're fleeing the police through the city, is it just going to be a fire escape rooftop chase, then a car chase, then a subway escape? Sounds like a generic movie.
My first idea was just to watch shows/movies with common themes to get ideas, but finding some place to talk about them like /lit/ might be better instead.
