I listened to this book on audio.
It was a fairly interesting listen, the narrator had a nice Italian accent that contributed a lot to my enjoyment of this novel. It's the horrible story of a serial killer in Florence, Italy. One whose identity remains a mystery to this day.
I learned that Italian police procedures are not reliable and they are unlike anything that we hear about in the U.S. I also learned that the Italian police and investigators do not require the same types of evidence that we do to obtain warrants or to interrogate people. This book made me very glad to be a U.S. citizen.
Anyway, this was an enjoyable "read"- quite different from anything I've read from Douglas Preston before. Sadly, the real killer was probably laughing at the police as they were interrogating Mr. Preston and Mr. Spezi. He is probably still laughing right now, if he's still alive. Just the thought of a killer like that being free is chilling. If you read this book, you will be chilled as well.
