When my sister learned that I had been reading antique book mysteries, she thrust this into my hands. The main character of this book is actually a bookscout of a sort, tracking down and buying or otherwise obtaining the rarest of the rare books in Europe. And, of course, a book he is commissioned to attain has a mystery associated with it. Actually, there are two mysteries that interweave and may or may not be related. There are many sumptuous books and a lot of lovely libraries and a lot of fanatical book folk. Perez-Reverte is a skillful storyteller and a great writer. The story has a lot of depth, depending on how much you know about the subjects he discusses: the devil, angels, the Three Musketeers, Alexander Dumas. Lots of interesting characters, a top notch book about books.
