Clifford Michael Irving (born November 5, 1930) is an American novelist and investigative reporter. Although he has published 20 novels, he is best known for a fictional autobiography of millionaire recluse Howard Hughes, which was to be published in 1972. After Hughes denounced him and sued the publisher, McGraw-Hill, Irving and his collaborators confessed to the hoax. He was sentenced to 2 1⁄2 years in prison, of which he served 17 months.
Irving wrote The Hoax (1981), his account of events surrounding the development and sale of the fake autobiography. The book was adapted as a 2006 biopic of the same name, starring Richard Gere as Clifford Irving. He has continued to write, and publishes his books as e-books available via Kindle and Nook.
