Book excerpt: “A stunningly detailed history . . . from sexy socialite double agents to ‘kill switches’ implanted offshore in the computer chips for our electric grid” (R. James Woolsey, former director of Central Intelligence). 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, sophisticated cyberspying, and a West Coast spy ring whose members were sentenced in 2010. As concerns swirl about US-China relations and the challenges faced by our intelligence community, Tiger Trap provides an important overview from “America’s premier writer on espionage” (The Washington Post Book World). “Wise’s conclusion is sobering—China’s spying on America is ongoing, current, and shows no signs of diminishing—and his book is a fascinating history of Chinese espionage.” —Publishers Weekly “A fact-filled inside account, with sources named and no one spared.” —Seymour M.
