Karen Hahn, who works for Custer Battles at the airport, started out there screening women passengers—and learned a lot from their handbags. Unlike most people Nancy met in Iraq, Karen is not a former military person, she doesn't work with guns or big machines, and she's never been happier in her life.

A former military man, Hank was hired by Custer Battles to clean up one of its other Iraq operations, guarding businessmen. He has a very clear idea of who he wants working for him: "flat-bellied, steely-eyed professionals." Instead, he's trying to tighten up a outfit whose workers once engaged in an extended firefight at a Baghdad hotel—against each other.

Hundred of Iraqi police officers have been killed since the United States invaded Iraq. One Boston cop, Jerry Burke, is trying to keep them on the job, and train them in Western police practices.
