Susan Carter's idyllic Bavarian holiday was rudely shattered while picnicking on the hillside by the sound of a speeding car, followed by a crash. Looking through her binoculars she saw the occupants leave their wrecked car and then take off in her own small Morris. If only Susan hadn't read the newspaper account of the murder of a German minister! If only she hadn't recognized the photograph of the car—said to have been used by the assassins! For Susan life gradually takes on the horror of a nightmare. Nor does she know which of her 'rescuers' to trust —Stephen Maitland or Gunther Cliburn.
