The Jade Cross

Master Gunnery Sergeant Travis Tolbane, USMC (Ret), is leaving from an alleyway from his job as a mall security manager when he is ambushed by a trio of Vietnamese. Escaping from it by the arrival of Metro Police, he finds out from his friend, Detective Sergeant Parnell, that Tolbane's friend Ba, his old interpreter from Vietnam, has been mutilated.
He; his live-in Vietnamese girlfriend, Mai, who is Ba's half sister; an old Marine friend Parnell; and a Vietnamese priest must stop a maniacal piquerist, who thinks he is the reincarnated Thirteenth Century hero Tran Hung Dao, seeking an iconic Jade Cross and Tolbane's lover, Mai, to rebuild an old society, the No Name. They chase him from Honolulu to Kowloon, Hong Kong, where he leaves a string of bodies, and to Hoi An City, Quang Nam Province, in the Democratic Republic of Vietnam, for a final solution.
