The protagonist is Helene. Beautiful. Dominating. Free. Uninhibited. Her brief, daring and, in some ways, fascinating existence is rich in events which take her from the orphanage to becoming "Lady S", the splendid dominatrix of the House of the Governess, through the most diverse and peculiar life experiences: college student, lap dancer, top model and finally "Lady S", the talented profiteer of weakness and human perversions.
The weapons she uses to win complete freedom and material success are her extraordinary beauty and her bisexual nature which permit her to seduce, and at times, to love men and women. The three narrative levels - the narrator, Helene and the detective - and the enigmatic finale make the novel somewhat singular.
