These authors wrote popular novels, but for various reasons never published another novel in their lifetime.
While serving on a cargo ship in the Pacific during World War II, Thomas Heggen wrote a series of impressionistic scenes detailing the tedious life aboard a supply ship far from the action. After the war he turned his writings into a novel which became a huge best seller and then a hit Broadway play and movie. Heggen struggled with writer's block while trying to write a second novel and died under mysterious circumstances in 1949.
