The novel Animal Farm was an allegory about the dangers of Soviet communism and of the communist leader Joseph Stalin. It was first published shortly after the end of World War Two, as the Cold War was just beginning. Louise Hidalgo has been speaking to Orwell's adopted son, Richard Blair, about George Orwell's work, and about his memories of his father.
