Publisher's Synopsis
American MP Joe Washington, an investigator with the Provost Marshall's Office, and Australian Rose McAlister are swept back together when she returns to join Central Bureau, General MacArthur's code-breaking group of eccentrics in 'Brisbane's Bletchley Park'. Again and again, Joe is drawn to the Brisbane River. Reports of a man who jumped from a bridge, a code breaker allegedly drowned by suicide, and an arm with an unrecognisable tattoo fished out of the water at the submarine base. Together they follow the clues but are quickly drawn into the city's dark tank stream, filled with predators and conmen and Joe's nemesis, corrupt Queensland detective Frank Bischof.
