Hong Kong by Stephen Coonts

Jake Grafton takes his wife, Callie, along when the U.S. government sends him to Hong Kong to find out how deeply the U.S. consul-general is embedded in a political money-raising scandal. And why not? Jake and Callie met and fell in love in Hong Kong during the Vietnam War, and the consul-general is an old friend from those days, Tiger Cole.

The Graftons quickly discover that Hong Kong is a powder keg ready to explode. A political murder and the closure of a foreign bank by the communist government are the sparks that light the fuse . . . and Tiger Cole is right in the middle of the action.

When Callie is kidnapped by a rebel faction, Jake finds himself drawn into the vortex of a high-tech civil war. Drawing on the skills of CIA operative Tommy Carmellini, in order to save his wife Jake Grafton must figure out who he can trust-both among the Western factions vying for control of the volatile situation, and among the Chinese patriots fighting for their nation's future-and make sure the right side wins.
