Even more alarming, Nickie's first-class boyfriend, Duncan Reed, is pressing for a permanent relationship.
Nickie decides to dive into Zheng's spidery operation, intent on locating and freeing the girls caught in the human trafficker's sticky web, only to discover that Zheng was the one who spun the gossamer truth that's keeping her and Duncan apart.
