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.[1] Later works such as The Quiet American, Our Man in Havana and The Comedians also show an avid interest in the workings of international politics and espionage.
Greene suffered from bipolar disorder,[2] which had a profound effect on his writing, and drove him to excess in his personal life. In a letter to his wife Vivien he told her that he had "a character profoundly antagonistic to ordinary domestic life", and that "unfortunately, the disease is also one's material".[3]
