The nervous system

Decimal busies himself retrieving and hiding files of sensitive information from the office of his former boss, DA Daniel Rosenblatt, who's been dead for six weeks. I should know. I shot the man myself, as Decimal admits. U.S. Sen. Clarence Howard, apparently unaware Rosenblatt is dead, threatens Decimal into trying to locate Rosenblatt. Seeking leverage, Decimal finds it in a photo of Howard with a Korean prostitute. Decimal's frantic attempt to learn the girl's fate leads him into hostile Korean and Chinese enclaves as well as battles with troops and police in Howard's employ.
