I bought this book because I was writing a cozy murder mystery for the first time. It laid out everything I needed to know about this genre, including the setting, iconography, themes, tone, characters, and plots. This book helped me so much. I ripped apart most of what I had already written and started again. With this book by my side, I learned about The Crime, victims, suspects, and most importantly, the sleuth. I learned what works and what doesn't, where and how to sprinkle clues and red herrings. It was fun reading, too! If you're a new writer of a cozy mystery, this book is a necessity.
