Rather than repeat what has been written by others on this page, I'd only like to add that normally this book is not my usual cup of tea. I burnt out on the genre back in the 70's, and haven't felt the need to return to it. The front page of the newspaper has all the international intrigue I can handle. But this wonderful book , with its indepth psychological insights and interwoven histories, had me wishing I could call in to work so I could keep reading. It was given to me by someone whose taste I admire, so under his recommendation I gave it a shot. If it's possible, each section should be read (as all short stories should) in one sitting. The continuity and suspense are masterfully handled. Of particular interest is the reader's guide that follows the text which sheds illumination on the most potent section in the book.
