Since the war Graham Greene has travelled habitually to the world''s trouble-spots and has provided leading newspapers and journals with articles about what he saw. While contending that a writer must be free of political affiliations he has commmitted himself to many countries and causes, and while insisting that literature must never be used for political ends he has written novels informed by a political urgency. The Dangerous Edge is about his political reportage and how the observations that formed it were transformed into literature. It is about how a novelist who struggled to record public issues dispassionately became in the process an important political conscience.
