What is the theme in Scoop by Evelyn Waugh?

Waugh wrote that his main theme was "to expose the pretensions of foreign correspondents . . . to be heroes, statesmen and diplomats." In the novel, he pokes fun at the idea that the profession of journalism is characterized by a disinterested search for the truth. On the contrary, the only concern of the journalists is to file a story that will meet with the approval of their bosses at the newspaper.
