Query: You'll scream in frustration

I certainly felt like doing so when the murderer was unveiled. I won't give anything away if for some reason you decide to read this book, but believe me the murderer is the one person who absolutely could not have committed the crime... at least not without more explanation from Pozzessere as to the logistics of the crime. But I went back and checked and double-checked and I'm positive that this was a case of this author's habitual sloppiness with details. Forget this book. It's not worth the frustration.
