London, 1968 Twenty-six-year-old Rana Maddox, codenamed Domino, has caught the attention of British Intelligence. Her secret liaison with the United Kingdom's War Minister, Robert MacDowell has made headline news, and the Government has gone into crisis mode. Added to this, her brother, top nuclear physicist Alexandre Rigaud, has vanished in Istanbul, and the Government suspects foul play. Agent Harry Dean has been told to follow Rana wherever she goes and report on her every move. Harry dismisses Rana as a flighty bottle blonde who's all in a day's work, but Oxford University-educated Rana knows exactly how to play agents like Harry Dean. Rana's got one thing on her mind; revenge. Harry Dean is not going to get in her way.
