An Autumn evening in 1937. A German engineer arrives at the Warsaw railway station. Tonight, he will be with his Polish mistress; tomorrow, at a workers bar in the citys factory district, he will meet with the military attache from the French embassy. Information will be exchanged for money. So begins THE SPIES OF WARSAW , with war coming to Europe, and French and German operatives locked in a life-and-death struggle on the espionage battlefield. At the French embassy, the new military attache, Colonel Jean-Francois Mercier, a decorated hero of the 1914 war, is drawn in to a world of abduction, betrayal and intrigue in the diplomatic salons and back alleys of Warsaw. At the same time, the handsome aristocrat finds himself in a passionate love affair with a Parisian woman of Polish heritage, a lawyer for the League of Nations. Colonel Mercier must work in the shadows, amidst an extraordinary cast of venal and dangerous characters - Colonel Anton Vyborg of Polish military intelligence, last seen in Fursts THE POLISH OFFICER; the mysterious and sophisticated Doctor Lapp, senior German Abwehr officer in Warsaw; Malka and Viktor Rozen, at work for the Russian secret service; and Merciers brutal and vindictive opponent, Major August Voss of SS counterintelligence. And there are many more, some known to Mercier as spies, some never to be revealed.
