China Riddle

The FBI enlists a university professor and veteran undercover agent to investigate a challenging case that has stumped them for over a year. Highly confidential technical information is being stolen from a major American pharmaceutical company and ending up in a company in Shanghai, China. The agent and his wife, a retired FBI agent, are to slip into the private life of the prime suspect, a company employee, in hopes of discovering how he gets the stolen information to China. A gang-style assassination draws attention away from the suspect. Facing a dead end, the agent travels to China to interview an informant in the Chinese company for clues that may lead to the source of the data. He faces riveting encounters involving China's Ministry of State Security, the CIA, an U.S. Navy Seals. Back home, the scrap of information the agent was able to gain from the informant points to another suspect, the discovery of clandestine listening devices and illicit drug manufacturing, and another blind alley. An encounter with an armed kidnapper and a sadistic goon provides evidence for a successful conclusion.
