I was disappointed by this book. The mystery was good, but I found the alternating chapters between upstairs and downstairs to be distracting. I understand the popularity of the upstairs/downstairs situation, what with Downton Abbey being so popular, but I found the varying points of view to be distracting from the story. I also found the ending to be too "pat" and unrealistic. Too perfectly tied up and saccharine sweet. 
 With that said, I did enjoy the book and the mystery leading up to all this.
