For decades, California-based engineer Chi Mak quietly stole secrets on war-fighting technologies. He and his family members shared the intelligence with spies in China, giving Beijing astounding insights they hadn’t earned. Former FBI Special Agent James Gaylord takes us back to the elaborate investigation in 2004. Evidence gathered by his squad, call sign “SARA-4,” broke a string of FBI failures in the courtroom. Chi went to prison, but new problems arose. Jim’s account is documented in his book, Chasing Chi.
