[Heteronym]

I recently had the pleasure of reading Ernesto Sabato's The Tunnel, strenghtening my belief that Argentine literature was one of 20th century's greatest treasures.

Sabato's novel is a killer's examination of himself and of the motives that lead him to kill the only woman that understood his art, because the protagonist is a painter. It's full of post-WWII existentialist angst and nihilism. It's also not unsimilar to Mário de Sá-Carneiro's Lúcio's Confession.
