Query: Spy Novel Period Piece

Story is set just prior to WWI and is interesting on several levels. Oppenheim builds on the English mentality before WWI and how many of the English just did not believe in a threat from Germany. I like history so getting history with a spy novel with a little love story to go with it was fun to read. I am sure you will enjoy this novel.
