Dragon Key

In the dragon's lair. When an American operative is jailed, Mack Bolan must finish the agent's mission to smuggle a Chinese activist and his family out of the country. But getting the dissident away alive becomes a logistical nightmare for Bolan and the two inexperienced CIA agents assisting him. Not only are the Chinese authorities on their tail, but the activist insists on retrieving a stolen flash drive in Shanghai. The memory key contains sensitive information belonging to a renegade general.
As determined to recover the data as the dissident is, the general has hired a legendary assassin famous for eliminating anyone who gets in his way. In a battle where only one champion can survive, Bolan may have met his match. But the Executioner is used to fighting against overwhelming odds and has something much more important on his side-justice.
