Author

Particularly known novels, such as The Power and the Glory (1940), of British writer Henry Graham Greene reflect his ardent Catholic beliefs. The Order of Merit and the Companions of Honour inducted this English novelist, short story writer, playwright, screenplay writer, travel writer, and critic. His works explore the ambivalent moral and political issues of the modern world. Greene combined serious literary acclaim with wide popularity. Greene objected strongly to description as a “Catholic novelist” despite Catholic religious themes at the root of much of his writing, especially the four major Catholic novels: Brighton Rock , The Heart of the Matter , The End of the Affair , and The Power and the Glory . Other works, such as The Quiet American , Our Man in Havana , and The Human Factor , also show an avid interest in the workings of international politics and espionage. (Adapted from Wikipedia)
