A Lady's Guide To Etiquette And Murder - Dianne Freeman

American-born Frances Wynn, Countess of Harleigh is finally done with mourning the man who was found dead in another woman's bed. She needs to get away from the new heir to the title and with her own funds she leaves for London. An anonymous letter implicating her in the murder of her husband leads her down a track of investigating the truth. Add in her sister and a dashing new neighbour, who knows the truth too and you have a fun read.

I really enjoyed this one and I'm looking forward to reading more. Frances is well aware of the problems of society and keeping herself well regarded while also knowing that she wants some freedom. It's an interesting look at a turn of the 19th Century world of privilege.
