Ghost of a Chance

Plot:

A government agent sends Darien on a mission to keep a country's newly appointed Defense Minister from putting into play a weapon system that could be used against the U.S. They want Darien to pretend to be a ghost and talk him out of it; it appears the man is superstitious. But another group who wants the weapon system activated sends their own agent who can meld with water who claims to be a water spirit.
