After returning to China, he had assumed his military duties and also taught classes at the Chinese Academy of Military Science, where Deputy Director Wang had discovered him teaching the Citizen-Soldier in American Society course. Wang had been impressed by Zuo's scholarship, public speaking abilities, and keen sense of humor. Despite Zuo's youth and lack of experience, Wang had taken him under his wing and become his mentor. Wang's own ego was bolstered with every success that Zuo achieved.

Indeed, Zuo's remarkable ascension in the PLA was beyond his American employers' wildest dreams, and they had made him offers to extend his contract for another four to six years (he had already worked five). It seemed the higher Zuo rose, the less chance he would have of actually leaving the country.

Consequently, he had turned down their offer and had responded with one of his own: begin plans to get him out of the country immediately. If they did so, he would turn over intelligence he had gathered for the past two years on an operation known as Pouncing Dragon, one the DIA had queried him about in 2009, when they had first heard the phrase in Waziristan.

Zuo told them he had names, dates, and a forthcoming meeting day and time, but he would not deliver them unless they got him out of China. He was waiting for their reply.

As much as it pained him to abandon his post and leave his mother and ailing father behind, Zuo knew that the United States was where he belonged.

And he knew that if he remained at his post much longer, the deputy director would eventually discover his activities and, on a cold, dark night while Zuo was sleeping, a man would come into his apartment. They would call it robbery.

The deputy director clearly had a lot to hide, and Zuo's eavesdropping had yielded some puzzling blanks in his routines that left Zuo even more unnerved about the boss's connections and influence.

On the third Tuesday of every month, at exactly one in the afternoon, Wang made a phone call to a number in Geneva. And at least twice per month he took a clandestine lunch meeting outside the office.

Zuo wondered if the deputy director, like Zuo himself, had his own agenda. Zuo had considered asking the DIA if Wang was actually working for them. How ironic that would be, but no, that was hardly the case.

With a shivery sigh, Zuo returned to sorting and compiling his reports. In two hours he would need to brief the deputy minister on what was currently happening in the Taiwan Strait. However, Wang would only be half listening as he watched CNN via satellite and interrupted Zuo to decry the inaccuracies of the American media.

That night, as Zuo returned home to his apartment in a heavy rainstorm, he spotted a man in a dark blue raincoat huddled in an alcove across the street from his building.
