My wife recommended this book to me,she rated it highly. I liked most of the book, but the story seem to come unstuck about halfway and the ending , though perhaps right, was mismanaged . There ware several indicators along the route that were wrong. For example, why did he draw attention to himself by pointing out the needle injection in Alicia's wrist, when to say nothing would have been right. It is an interesting read ,but with an unsatisfactory ending. The actual subject master of the book was good
