Set against the East-West Cold War of the 1960s, this story follows intelligence agencies from China, Britain, and Eastern and Western Europe as they wage an intense spy war over the core technology behind a new communications system. The protagonist, Fang Jin, travels between countries, engaging in a series of humorous yet dangerous battles of wits with allies and adversaries such as Anna and Jack. The three volumes cover the battle for technology, covert infiltration, and the final showdown. Each volume has its own suspenseful plot, while all three are tightly interwoven. Humor cuts through the tension as the story explores the growth of its agents and their choices of faith. In the final great contest, one that will determine the shape of the world, Fang Jin must choose between trust and betrayal, and between ideals and reality.
