Having read all the books in this series, I will continue to do so but this one was a bit lacking. The characters are still intriguing but I think the relationship between Fremont and Michael needs to be finetuned. Fremont's reasons, or perhaps emotions, are not ringing true as to why she won't marry Michael. The plot revolves around seances and the spiritual world which were very important in that era and a wonderful foundation for a mystery. However, the details of the plot were loosely constructed and loosely solved. Michael's dealings with the spy world and Russia are mentioned and would be a great source for the next mystery embroiling Fremont and Michael together.
