Shirley Smith, a new pupil at Redcliffe Towers Boarding School, discovers that Petra Barnes has a hold over everyone to get her own way at everything. Even the headmistress is in Petra’s grip, so Petra can arrange to have girls expelled for crossing her, and several pupils go this way. Shirley is determined to find out what gives Petra her power over Redcliffe Towers.
