"Zodiac anyone?"
The only thing I could think about while listening to this book was the 2007 David Fincher film, Zodiac. The film is a modern classic thereby making it difficult for The Monster of Florence to compete when essentially dealing with the same topics, e.g. unsolved murders, the unyielding grip of obsession, etc. As for the narration, annoying. The faux Italian emphasis on pronunciation wore on me like a fire alarm that would not turn off. All in all, interesting topic made plain by something far better having preceded it. My advice, throw Zodiac in your Netflix queue and spend your Audible credit on something else.
