Uncle's Dream and the Permanent Husband by Fyodor Dostoevsky

Two classic novellas. According to Wikipedia: "Fyodor Mikhailovich Dostoyevsky (11 November 1821 – 9 February 1881) was a Russian writer of novels, short stories and essays. Dostoyevsky's literary works explore human psychology in the troubled political, social and spiritual context of 19th-century Russian society. A Slavophile, nationalist and monarchist, he criticised the bourgeois, pre-materialist West and nihilism in many of his works. Although Dostoyevsky wrote books in the mid-1850s which were influenced by realist and romanticist writers, most notably by Dickens, Gogol and Balzac, his best remembered work was done in his last years, including such masterpieces as Crime and Punishment, The Idiot and The Brothers Karamazov. Dostoyevsky overall wrote 11 complete novels, three novellas, seventeen short novels and three essays."
