Henry Graham Greene (2 October 1904 – 3 April 1991), better known by his pen name Graham Greene, was an English novelist regarded by many as one of the greatest writers of the 20th century. He was shortlisted, in 1966 and 1967, for the Nobel Prize for Literature. Through 67 years of writings, which included over 25 novels, he explored the ambivalent moral and political issues of the modern world, often through a Catholic perspective.

Although Greene objected strongly to being described as a Roman 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 Power and the Glory", "The Heart of the Matter", and "The End of the Affair", which have been named "the gold standard" of the Catholic novel. Several works, such as "The Confidential Agent", "The Quiet American", "Our Man in Havana", "The Human Factor", and his screenplay for "The Third Man", also show Greene's avid interest in the workings and intrigues of international politics and espionage.
