Query: ummm - where is the mystery?

You may think that you're buying a book of mystery stories, but no, the real mystery is why most of these stories in this volume aren't mysteries at all. If they had labeled this "Crime Fiction With No Mystery", then that would be more honest. Most of the stories in this volume have no real hidden element that keeps you guessing. Sure, there may be some good social commentary or character development here and there, but if I really wanted that stuff I wouldn't have picked up a book labeled "Mystery Stories".
