What is the author's style in Death and the Maiden by Ariel Dorfman?

Death and the Maiden is highly realistic in form and structure, with a plot that rapidly unfolds in linear progression, characters that are fully-realized individuals, and a fixed, recognizable setting. Dorfman breaks with this basic structure only at the end of the play, when the setting jumps to a concert hall several months later. At this point, the playwright introduces an expressionistic device, a mirror aimed at the audience, to bring thematic unity to the piece.
