The nice thing about your police procedural as opposed to your classic murder mystery is that in a murder mystery you don't know who did it. Whereas in a police procedural you know, you know everything often and you're watching the police home in.
Terry PratchettWho knew what evil lurked in the hearts of men? A copper, that's who. (...)You saw how close men lived to the beast. You realized that people like Carcer were not mad. They were incredibily sane. They were simply men without a shield. They'd looked at the world and realized that all the rules didn't have to apply to them, not if they didn't want them to. They weren't fooled by all the little stories. They shook hands with the beast.
Terry PratchettAnd then Jack chopped down what was the world's last beanstalk, adding murder and ecological terrorism to the theft, enticement, and trespass charges already mentioned, and all the giant's children didn't have a daddy anymore. But he got away with it and lived happily ever after, without so much as a guilty twinge about what he had done...which proves that you can be excused for just about anything if you are a hero, because no one asks inconvenient questions.
Terry PratchettMere animals couldnโt possibly manage to act like this. You need to be a human being to be really stupid.
