Everybody liesespecially in wartime. Individuals do it for personal advantage. Governments do it for political and strategic reasons. General Donovan, the director of the US militarys Office of Strategic Services sends officer Charles Worthington in early 1944 to open a direct liaison relationship between the OSS and the Soviets civilian intelligence service, the NKVD. The exchange program turns out to be a waste of time, but then Charles receives a discreet offer from an NKVD official. He claims to have information about NKVD penetrations within a secret American weapons program called the Manhattan Project, which is supposedly developing something called an atomic bomb. In return, the Russian wants to be smuggled to America to begin a new life. His life is also complicated by his growing fondness for an attractive female employee at the British embassy in Moscow, efforts by various Russian informants around him, and the harsh Russian winter. In the end, he must decide whether he will do what is best for himself or best for America.
