Wives and Daughters, by Elizabeth Cleghorn Gaskell, free for your kindle if you click on the title.
I read and loved it. I how well she develops the characters, and how interesting the interactions between classes, the topics of honor, love, personality, duty. It was a wonderful read.
Vanity Fair, also free for Kindle. I am currently reading it, and liking it much too.
And since I had never read any Agatha Christie novels, I read two which were also highly satisfactory.
There is a Tide
Curtain, the last Poirot case. It was phenomenal. I recommend some Agatha Christie. I like her study of personality too, and there is some logic to be learned from her novels.
A Sherlock not by Doyle, The Seven Per Cent Solution, featuring Freud along with Watson and Holmes, and Holme's brother as well as Dr. Moriarty. A classic for Sherlock fans.
