Something unique about this book (to me as a reader) was the killer's identity revealed early in the book. I believe it was in the second chapter. I thought, how can you keep the book interesting when I already know "who done it?" The best part of the book, in my opinion, was the killer: clever enough not to get caught and crazy enough to want to continue killing. But eventually, they pushed their luck too far and got their just rewards. There were some minor editing issues and some unnecessary paragraphs that slowed the narrative. Overall, I found it entertaining for the unlikely bad guy and how they eluded capture.
