Poor Folk, sometimes translated as Poor People, is the first novel by Fyodor Dostoevsky, written over the span of nine months between 1844 and 1845. Dostoyevsky was in financial difficulty because of his extravagant lifestyle and his developing gambling addiction; although he had produced some translations of foreign novels, they had little success, and he decided to write a novel of his own to try to raise funds.
Varvara Dobroselova and Makar Devushkin are second cousins twice-removed and live across from each other on the same street in terrible apartments. Devushkin's, for example, is merely a portioned-off section of the kitchen, and he lives with several other tenants, such as the Gorshkovs, whose son groans in agonizing hunger almost the entire story. Devushkin and Dobroselova exchange letters attesting to their terrible living conditions and the former frequently squanders his money on gifts for her.
The reader progressively learns their history. Dobroselova originally lived in the country, but moved to St. Petersburg (which she hates) when her father lost his job. Her father becomes very violent and her mother severely depressed. Her father dies and they move in with Anna Fyodorovna, a landlady who was previously cruel to them but at least pretends to feel sympathy for their situation. Dobroselova is tutored by a poor student named Pokrovsky, whose drunken father occasionally visits. She eventually falls in love with Pokrovsky. She struggles to save a measly amount of money to purchase the complete works of Pushkin at the market for his birthday present, then allows his father to give the books to him instead, claiming that just knowing he received the books will be enough for her happiness. Pokrovsky falls ill soon after, and his dying wish is to see the sun and the world outside. Dobroselova obliges by opening the blinds to reveal grey clouds and dirty rain. In response Pokrovsky only shakes his head and then passes away. Dobroselova's mother dies shortly afterwards, and Dobroselova is left in the care of Anna for a time, but the abuse becomes too much and she goes to live with Fedora across the street.
Devushkin works as a lowly copyist, frequently belittled and picked on by his colleagues. His clothing is worn and dirty, and his living conditions are perhaps worse than Dobroselova's. He considers himself a rat in society. He and Dobroselova exchange letters (and occasional visits that are never detailed), and eventually they also begin to exchange books. Devushkin becomes offended when she sends him a copy of "The Overcoat", because he finds the main character is living a life similar to his own.
Dobroselova considers moving to another part of the city where she can work as a governess. Just as he is out of money and risks being evicted, Devushkin has a stroke of luck: his boss takes pity on him and gives him 100 rubles to buy new clothes. Devushkin pays off his debts and sends some to Dobroselova. She sends him 25 rubles back because she does not need it. The future looks bright for both of them because he can now start to save money and it may be possible for them to move in together.
