November, 1940. I.A. Serebin, a writer from Odessa and former decorated Hero of the Soviet Union, is on his way to Istanbul following a cryptic letter from a former lover. Ostensibly there on official business for the International Russian Union, an emigre organisation based in Paris, he is drawn into a clandestine world of international spies and political players. With war in Europe drawing nearer, Serebin is recruited by the British secret services his mission to stop the export of Roumanian oil to Germany. In a race against time, Serebin's journey will take him from the glittering salons of Paris to the back alleys of Bucharest and the Black Sea ports, in a covert operation to staunch the flow of oil, the precious 'blood of victory'.
