Provide a short summary of Chinua Achebe's novel, Anthills of the Savannah.
Nigerian author Chinua Achebe provides another glimpse of African political unrest in his novel, Anthills of the Savannah. The novel tells the story of three longtime friends--Sam, Chris Oriko and Ikem Osodi--who have ascended political power in the fictitious country of Kangan. Sam, the president, has dictatorial dreams, but Oriko, Commissioner of Information, and Osodi, editor of the national newspaper, are more moderate. When Oriko and Osodi protest too vehemently, Osodi is murdered by state police, and Oriko is forced into hiding. Oriko successfully escapes from the capital and, on the way to freedom, is greeted with the news that Sam has been assassinated by a coup. But before Oriko can revel in his country's new leadership, he, too, is killed trying to prevent the rape of one of his friends.
