Mario Puzo, who has died aged 78, said of his worldwide, bestselling novel The Godfather: "I wished like hell I'd written it better."
Puzo's remarkable success came about because he was broke and determined to write something which would make him money. He had a wife and five children to support.
"I was 45 years old, I owed $20,000 to relatives, finance companies, banks and assorted bookmakers and loan sharks. It was really time to grow up and sell out."
