What is the author's style in Invitation to a Beheading by Vladimir Nabokov?

Most of Nabokov's novel is told from a third person semi-omniscient point of view, from the perspective of Cincinnatus. Most of the characters are unreal, cardboard cutout imitations of people. Cincinnatus calls them "parodies." His perspective is the point of view of the novel because it is the only valid perspective among all the superficial, unreal characters. Any thoughts or emotions that the other characters possess are hidden under layers of artifice built up by societal expectations.
