Effi Briest.

Effi Briest is a realist novel by Theodor Fontane. Published in book form in 1895, Effi Briest marks both a watershed and a climax in the poetic realism of literature. It can be thematically compared to other novels on 19th century marriage from a female perspective, such as Anna Karenina and Madame Bovary, which are also adultery tragedies.
