"Clifford Michael Irving (born November 5, 1930) is an American investigative reporter and writer. He is known for a fake "autobiography" of Howard Hughes in the early 1970s. After Hughes denounced him and sued McGraw-Hill, the publisher, Irving confessed the hoax and was sentenced to two-and-a-half years in prison, serving 17 months."--Wikipedia.
