Delta File by Dale A. Dye

A bit bored and in a contemplative mood, Gunner Shake Davis examines a pile of long-forgotten family heirlooms and discovers a couple of mysterious relatives that pique his interest: A Confederate Navy riverboat captain and a World War I Marine who fought at Belleau Wood. In an attempt to learn more about those intriguing kinsmen, Shake undertakes a nostalgic road trip back to his old home ground. Memory Lane becomes a deadly minefield when he stumbles on a gruesome human organ harvesting operation running right in the American heartland.
