Heart of Darkness (1899) is a novella by Polish-British novelist Joseph Conrad, about a voyage up the Congo River into the Congo Free State, in the heart of Africa, by the story's narrator Charles Marlow. Marlow tells his story to friends aboard a boat anchored on the River Thames, London, England. This setting provides the frame for Marlow's story of his obsession with the ivory trader Kurtz, which enables Conrad to create a parallel between London and Africa as places of darkness.
Doctor Marigold, named for the man who delivered him, is a "cheap-jack" who hawks sundries from a traveling cart he inhabits with his wife and his daughter Sophy. The mother beats Sophy, but Marigold, feeling powerless, does nothing to stop her. When the child dies of a fever, her guilt-wracked mother commits suicide.
