This had some great parts to it, but the ending was a little bit of a letdown. The motivation for the one committing the crimes was a bit off-the-wall and was an absolute stretch as to why they were doing what they were doing. I also wanted a little more character development on the relationship between the 2 sisters in the past but you still get the gist with what's provided. I did really enjoy how detailed the descriptions of all the locations in Paris were so if anything you'll get a nice little imaginary vacation through this book.
