J K Rowling wouldn't be J K Rowling if she didn't have encased in her books endless chapters that don't really matter. That being set aside, this book is actually well thought out. A little too much when it comes to the preservation of suspense till some 95% of the book but enjoyable because of the remarkable fluidity of her language. Fans of Rowling will be pleasantly surprised at how explicit she can be after spending almost two decades writing a children's series. A well scripted, quite true to classic but modernized example of quality British crime.
