French Revolution mysteries
If you like reading historical mysteries, there is a series set in Paris before and during the French Revolution by Susanne Alleyn: The Cavalier of the Apocalypse, Palace of Justice, Game of Patience, A Treasury of Regrets. They are quite accurate historically and give a good sense of the atmosphere of the city at that time, especially during the Terror and after. The main character/detective works unofficially for the police. The author has a website: http://susannealleyn.com/ with more details on the books, and I found them at my local library.
