Henry Graham Greene, OM, CH was an English novelist, short story writer, playwright, screenplay writer, travel writer and critic whose works explore the ambivalent moral and political issues of the modern world. Greene combined serious literary acclaim with wide popularity.
Although Greene objected strongly to being described as a “Catholic novelist” rather than as a “novelist who happened to be Catholic,” Catholic religious themes are 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. 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.
