For decades, while America obsessed over Soviet spies, China quietly penetrated the highest levels of government. Now, for the first time, based on numerous interviews with key insiders at the FBI and CIA as well as with Chinese agents and people close to them, David Wise tells the full story of China's many victories and defeats in its American spy wars. Two key cases interweave throughout, Katrina Leung, code-named Parlor Maid, worked for the FBI for years, even after she became a secret double agent for China, aided by love affairs with both of her FBI handlers. Here, too, is the inside story of the case, code-named Tiger Trap, of a key Chinese-American scientist suspected of stealing nuclear weapons secrets. These two cases led to many others, involving famous names from Wen Ho Lee to Richard Nixon, stunning national security leaks, and sophisticated cyber spying. The story takes us up to the present, with a West Coast spy ring whose members were sentenced in 2010 - but it surely will continue for years to come, as China faces off against America. David Wise's history of China's spy wars in America is packed with astonishing revelations.
