John Franklin Kincaid clocks out at 4 PM on Thursday, August 27, 1953, after his shift at New York Shipbuilding Corporation's sprawling shipyard in Camden, New Jersey, never to be seen or heard from again. A little more than a decade later, a little girl is assailed by a terrible recurring nightmare. She dreams she is a man, buried alive in a dark compartment in the bowels of a ship under construction. On November 16, 1963, President Kennedy helicopters to that ship, now a US Naval vessel called the USS Compass Island, as it steams off the coast of Florida to witness the firing of a Polaris missile clandestinely targeting Cuba's Fidel Castro. And so topple the first dominoes in a chain of events leading inexorably to the president's assassination one week later in Dallas, Texas. Who killed JFK -- the president and shipyard worker? The answers abide on the Compass Island as the old ship casts off on its final voyage to the scrap yard in October of 2003 with descendants of John Franklin Kincaid on board and determined to solve not one, but two murder mysteries.
