The Venona Kid

The year is 1948. Soviet spies in the Untied States are receiving encoded messages from Moscow. The United States responds with the Venona Project - employing code breakers with early IBM machines to decode the Soviet communications.
This is the story of Robert Thompson, a high-school student who was accepted as an intern to assist with the Venona project. It turns out he is a skilled decoder and has the upper management of the Army Intelligence Service asking for his help to decode messages. But will this put his own life at risk?
