Half–Vietnamese, half–black, Baltimore county cop Luther Ewing is known as "the Comanche" to his Gulf War buddies, "Shooter" to his fellow mercenaries in Bosnia, and "Five–O" to the Baltimore narc squad he works with. But after being suspended from duty for six months as the scapegoat in a case gone bad, Luther goes undercover as Terrance Prentice, working for the CIA, something he swore he'd never do again. His job––guarding a South Korean business man with ties to the US government. The deal––trading two million dollars for some advanced technology with some renegades from the Russian military. Only Luther doesn't know the whole score. And the only people on his side may be the very people he should fear.
