I love this quote from a character in The Sherlockian by Graham Moore. He is trying to describe why he loves Holmes and mysteries.
"I think I love the idea that problems have solutions. I think that's the appeal of mystery stories, whether they're Holmes or someone else. In those stories we live in an understandable world. We live in a place where every problem has a solution, and if we were only smart enough, we could figure them out....As opposed to a world that's random. Where violence and death are happenstance-unpreventable and unstoppable.
