In the last days of the Third Reich, the Nazis organized a "Werewolf" underground organization to wage a guerrilla war against the Allies. The most treasured relics of the Third Reich were hidden to serve as the spiritual center of a new underground (the Nazi Party "Blood Banner" has never been found). Largely unsuccessful, the Werewolves did succeed in killing several Allied officers and anti-Nazi Germans.
Charles Whiting's suspenseful narrative concentrates on a small Werewolf team assigned to kill the pro-American mayor of Aachen. The tension builds as terror and counter-terror units move toward a fatal confrontation.
