In 1989, the Berlin Wall fell; shortly afterwards the two Germanies reunited, and East Germany ceased to exist. In Stasiland, winner of the 2004 Samuel Johnson Prize, Anna Funder tells extraordinary tales from the underbelly of the former East Germany, a country where the headquarters of the secret police can become a museum literally overnight, and one in fifty East Germans were informing on their countrymen and women. She meets Miriam, who as a sixteen-year-old might have started the Third World War, visits the man who painted the line which became the Berlin Wall and gets drunk with the legendary ''Mik Jegger'' of the East, who the authorities once declared - to his face - to ''no longer exist''.
