Book #3 in the Karl Adams series.
Karl Adams is now deep undercover for the CIA working inside Russia and just completing training as an SVR officer. In a fascinating twist, one of his first assignments for that Russian spy organization is to travel to America to go undercover in a high-tech aerospace company as an engineer. His dilemma is that the more hi-tech he steals, the better his rise in the SVR but the more harm he does to his actual country.
