This is one of the best-written and most logically thought out mysteries I have ever read. Mr. Hyde has obviously done his homework, and knows exactly how to keep the suspense at a consistently high level throughout the book. I'm very tempted to buy another of his books, although I understand from the critics' reviews that this book is something of a change of pace for Mr. Hyde, and so I'm a little unsure about it. I would have given the book five stars, except for the items already mentioned in other reviews (a second autopsy on a body, the VERY detailed descriptions of what happens during a bombing raid), and the very intense description of the killer's home toward the end of the book - up until then I was reading each page very slowly, but I sped through this part - it really turned my stomach.But that aside, this one heckuva good read.
