The Kremlin Letter

The Tillinger Foundation, which is dedicated to missions of higher culture and which has ramifications all over the world, is in reality one of the most important centres of specialised espionage of the United States. A network of older spies from the West recruits a young intelligence officer with a photographic memory to accompany them on a mission inside Russia. They must recover a letter written by the CIA that promises American assistance to Russia if China gets the atomic bomb.
