"I'm involved in a dangerous game,
Every other day I change my name,
The face is different but the body's the same,
Boo, boo, baby! I'm a spy!"
- Popular song in wartime Istanbul

Istanbul in 1942 is a neutral city, packed with spies. Everyone's here - the Nazis, the Soviets, the Brits and the Yanks, the Japanese and a host of other nations, all waging a deadly war of wits against a backdrop of cocktail bars and polite smiles. From the infamous Snake Pit in the Park Hotel, to the jazz clubs and fashionable restaurants of Istiklal Avenue, to the warrens of alleys around the spires and mosques of Fatih and Sultanahmet, it's a city in ferment. While Turkey desperately tries to stay out of the war, the Führer's armies mass less than a hundred miles away.

But that's not all. Something even more terrifying is going on beneath the ancient streets of the Sublime Porte. Meddling forces have unearthed an ancient treasure, setting in motion plans centuries old which threaten to change the course of the whole war - and even the world!
