SHADOW CHASE  A high-ranking Chinese official has arranged to defect to the United States and reveal war crimes his country has perpetrated throughout Asia. But while en route to discreetly bring the official to American soil, Mack Bolan learns the man has been arrested, and the mission becomes much more urgent. And dangerous.  Bolan's first stop, the notorious prison where the official is being held, is a trap he barely escapes. On the run through the streets of Beijing, with intelligence agents hot on his trail, time is running out to recover the defector. And when his search-and-rescue leads him to a government-sanctioned organ-harvesting facility, the Executioner adds search-and-destroy to his list of things to do before his trip to China is complete.
