With the exception of the more-detail-than-needed descriptions of certain scenes, this was a very good story. I loved the look into the "daily lives" of people in the nineteenth century. The whole mystery surrounding Harry and his codes was so fun to read. I loved the end when the story picked up and the conflict was palpable.
Overall, a good book; the only thing that I disliked was the 'R' rated sex scenes. Honestly, if it was a Nora Robert's type of scene, it would have the story so much better, in my opinion.
I liked it well enough. The story was good and I loved the mystery and the descriptions of mundane life. Plus it had a happy ending! Those always make me happy.
