Arriving in Nazi Germany, Englishman Conrad de Lancey feels sick at heart.
Even Berlin - infamous haven of decadence and vice - salutes fascism.
Himmler's black-shirted troops rule the city, and every German arm bears a Swastika.
But does every German heart belong to Hitler? When Conrad is arrested by the Gestapo on suspicion of spying, he is rescued by Theo, an old friend from university, now a lieutenant of the Wehrmacht.
Together they are drawn into a world of danger and deceit, of plots, paranoia and intrigue where the brave few are united by a single ambition: to free the fatherland from the Fuhrer.
