At the bookstore a whole wall of noir stories by cities greeted me. My immediate response was a question: What’s the difference between noir, mystery, and horror? I remember bookstores used to shelve them all together under mystery. According to the clerk, noir is a style, horror and mystery are genres. Incidentally, the modern mystery genre actually originated from horror, more specifically from Romantic horror. The noir style is usually associated with early- to mid-20th century mystery stories that tend to share some elements of some of the more realistic horror stories. Whether you should buy them depends on what you like. If you’re a fan of horror, you could do worse than a collection of noir stories. If you like mystery, it’s probably a good investment.
So complete and straight-forward. This is why I love my local bookstores.
