suspense

Nathan Tyler is an unassuming, brilliant mathematics professor who is surprised by a sudden call he receives one morning. The American government wants his help, they say, to work on something important, for which he has to travel to Russia. Professor Fergusson thinks that he is crazy – which American would go to Russia when international political tensions are running so high? But Tyler agrees to do the job because this could be a once-in-a-lifetime opportunity. And the stakes are high, he could even get killed or lost or kidnapped, who knows?
