Chronically underemployed Japanese-American sleuth Rei Shimura has taken a freelance gig with a Washington, D.C., alphabet agency that just might have ties to the CIA. Her mission, should she choose to accept it, is to go undercover as a clerk in a big Tokyo department store. It's a risky assignment, but it also gives Rei a store discount that allows her to freely indulge her shopaholic tendencies. Meanwhile, she's listening in on private conversations, crashing a conference, and fending off the unwanted advances of a couple of the store's executives who seem fascinated by her navel ring. When her cover is blown, Rei is in big trouble. Suddenly she's neck-deep in something very nasty, and it will take all her resourcefulness and unorthodox methods to survive a determined killer.
