Lucky Leung

To put it mildly, Katrina Leung was a lady of many hats. Arriving from southern China at the age of 15, she became a successful entrepreneur and socialite, and later a donor and fund-raiser for political campaigns in California.

Most importantly, though, she was one of the FBI's most prized sources on matters Chinese for two decades, during which she was paid $1.7m (£1m) for services to national security. Alas, she may have been working for her country of birth all along.

This modern spy story became public on 9 April, when Ms Leung was arrested at her Los Angeles home on charges of improperly copying classified documents. Taken into custody with her was her FBI handler James J ("JJ") Smith, who had won a CIA intelligence prize largely on the strength of the information he had been passed by Ms Leung. The details were deemed precious enough to be worthy of presidential attention.

But the professional relationship gradually became personal, and the two began an affair that would lead to Mr Smith's disgrace.

Alleged Agent Gets Limited Indictment

A federal grand jury has issued a limited indictment against alleged Chinese double agent Katrina Leung, listing five charges that do not amount to espionage.

The charges come on the heels of similarly oblique charges against the retired FBI agent identified as her lover.

Prosecutors say Leung, a valuable FBI source of Chinese intelligence for 18 years, was passing secret information obtained from Smith to China, including information from FBI files regarding Chinese fugitives, a telephone list of agents involved in an espionage case, lists of agents serving at overseas posts and other classified information.
