Extinction takes the form of the autobiographical testimony of Franz-Josef Murau, the intellectual black sheep of a powerful Austrian land-owning family. Murau lives in Rome in self-exile, obsessed and angry with his identity as an Austrian, and resolves never to return to the family estate of Wolfsegg.[2] He is surrounded by a group of artistic and intellectual friends, and intends to continue living what he calls the Italianate way. When he hears of his parents' deaths, he finds himself master of Wolfsegg and must decide its fate.
Murau has cut himself off from his family and sought to establish an intellectual life as a tutor in Rome. In the first half of the novel, he reflects on the spiritual, intellectual, and moral impoverishment of his family to his Roman student Gambetti. He only has respect for his Uncle Georg, who similarly cut himself off from the family and helped Murau to save himself. In the second section, he returns to his family’s estate, Wolfsegg, for the funeral, as well as to determine the disposal of the estate, which is now in his hands.
Throughout the novel, Murau talks about the void that he has created for himself via exaggeration combined with understatement. Murau then incriminates all of art in this role of unjustified absolution. To Gambetti, the "great" of "great art" was just that; when he thinks on his villa in Wolfsegg, "great" comes to mean something new: criminal art that has the power to make people pardon themselves for mortal sins.
Gambetti is Murau’s collaborator. His presence provides the mirror to the society of his parents, and reveals that Murau too has established an audience for himself that unknowingly endorses his obscure tactics. He stops speaking to Gambetti in the second half of the novel because Gambetti has been an agent in Murau’s self-deception. This in turn allows Murau to write his Extinction.
