La sombra de Heidegger (English: The Shadow of Heidegger) is a 2005 thriller written by the Argentine philosopher and novelist José Pablo Feinmann. It depicts an exiled Nazi professor called Dieter Müller who writes a letter to his son, in which he describes the philosophy of Martin Heidegger as the spiritual guidance of the Nazi Party. Besides, La sombra de Heidegger has some elements that would enable it to be included in the category of historical novel. Although there are fictional characters, most of the people involved in the novel are public—and often controversial—figures, such as Adolf Hitler, Ernst Röhm, Jean-Paul Sartre and so on.The novel also covers topics of Argentine political life. More than once Müller satirizes the situation of peronism in Argentina.
