November 1940. The Russian writer I. A. Serebin arrives in Istanbul by Black Sea freighter. Although he travels on behalf of an émigré organization based in Paris, he is in flight from a dying and corrupt Europe -- specifically, from Nazi-occupied France. Serebin finds himself facing his fifth war, but this time he is an exile, a man without a country, and there is no army to join. Still, in the words of Leon Trotsky, "You may not be interested in war, but war is interested in you." Serebin is recruited for an operation run by Count Janos Polanyi, a Hungarian master spy now working for the British secret services.

The battle to cut Germany's oil supply rages through the spy haunts of the Balkans; from the Athenée Palace in Bucharest to a whorehouse in Izmir; from an elegant yacht club in Istanbul to the river docks of Belgrade; from a skating pond in St. Moritz to the fogbound banks of the Danube; in sleazy nightclubs and safe houses and nameless hotels; amid the street fighting of a fascist civil war.
