Infamous for the murder of Maria Iribarne, the artist Juan Pablo Castel is now writing a detailed account of his relationship with the victim from his prison cell: obsessed from the first moment he saw her examining one of his paintings, Castel had become fixated on her over the next months and fantasized over how they might meet again. When he happened upon her one day, a relationship was formed which swiftly convinced him of their mutual love. But Castel's growing paranoia would lead him to destroy the one thing he truly cared about...Sabato's first novel "El Tunel" (translated as "The Outsider" or "The Tunnel"), written in 1948, is framed as the confession of the painter Juan Pablo Castel, who has murdered the only woman capable of understanding him. Sabato's novels were praised by authors such as Albert Camus and Graham Greene.
