Since the U.S. had announced the sale of that submarine to Taiwan nearly thirty days prior, the entire Nanjing region had been at the highest military alert, and the office had been flooded with intelligence. The PLA's "training" exercises in the Taiwan Strait, along with the repositioning of troops, had resulted in the U.S. deploying a second carrier task force to the area as the American president continued to rattle his saber and caution the Chinese government about making any moves against Taiwan.

In response, China's air force had repositioned fighter and aircraft bomber squadrons, and on recommendation of Deputy Director Wang, the commander of the PLA Navy had ordered two Shang-class nuclear fast-attack submarines from its North Sea Fleet at Qingdao to the East Sea Fleet. That action doubled the number of Shang-class subs under operational control of ESF Vice Admiral Cai Ming, a fact quickly publicized online via the PLA Daily English News.

And just today, after a long month of uneasiness, the president, vice president, and premier of Taiwan, obviously threatened by China's significant show of force, had agreed to declare martial law. Chinese agents and sympathizers were being rounded up and imprisoned while the government and the Pan-Green Coalition--composed of the Democratic Progressive Party, the Taiwan Solidarity Union, and the Taiwan Independence Party--now threatened to declare Taiwan's independence from mainland China.

The Americans had a metaphorical term for such a situation; they called it a powder keg.

Zuo showed the general into the deputy minister's office, closed the door, then returned to his chair. He wrung his hands and thought of slowing his pulse. It was just another day. Nothing to worry about. When it was over, he would return home to his little apartment and relax with a bottle of Tsingtao and a pack of cigarettes.

Life had been much easier back in the United States. Zuo had done his undergraduate work at Shanghai Jiao Tong University, earning an engineering degree. The following year he had enrolled in a joint program with Drexel University in Philadelphia to earn his graduate degree.

While in the United States, he had stayed with a host family whose son was an army captain, and they had developed a strong friendship. Moreover, Zuo's perceptions of America and American culture were transformed during his four years of study. A country he had once described in a school paper as the home of the corrupt and selfish had become something very different.

His home.

Knowing that Zuo would return to China to perform his "sacred duty" as a citizen and serve in the military, representatives of the U.S.'s Defense Intelligence Agency (DIA) had recruited him as an operative with the promise that if he worked for them for no less than six years, they would help him defect and become an American citizen.

Zuo had agonized over the decision for months, but finally he had agreed.
