They approach salesman Greville Wynne to go to Moscow under the pretense of exploring commercial opportunities. Wynne establishes seemingly normal business relations with Penkovsky and the latter makes arrangements with western intelligence agencies to feed them information. He asks that they continue to use Wynne as their regular courier, reasoning that he will be under the Soviets' radar. Initially opposed to the task, Wynne eventually agrees, partly after CIA officer Emily Donovan emphasizes that his efforts could help prevent a nuclear war and also after Penkovsky visits him at his home and tells him that he is betting his life on Wynne's success.
