Soriano became a staff writer at La Opinión right from the start in 1971 when editor Jacobo Timerman founded the newspaper. La Opinión was permeated with progressive politics and soon there was an attempt to squash the left-wing influence with-in the paper. After six months of not having any of his articles published, Soriano began writing a story in which a character named Osvaldo Soriano reconstructs the life of English actor Stan Laurel. The work became his first novel, Triste, solitario y final (English: Sad, lonely and final), a melancholic parody set in Los Angeles with the famed fictional Philip Marlowe detective as his joint investigator. It was some months after the publication of his novel that he visited the American city, and actually stood by the grave of Stan Laurel, leaving there a copy of his book. Shortly after the Proceso de Reorganización Nacional coup d'etat in Argentina in 1976, he moved to Brussels first (where he met his wife Catherine), and then to Paris, where he lived in exile until 1984. While in France he befriended Julio Cortázar with whom he founded the short-lived experience of the monthly magazine Sin censura. After the fall of the military junta he returned to Buenos Aires and the publication of his books were met with large success, not only in South America but also in Italy and several other countries where his works begun to be translated and published. In his books, Soriano succeeded in mixing his experiences as a democratic activist and as a strong critic of the violence wielded by reactionary governments with extraordinary humour. A lover of both football/soccer and cinematography, he often honored both in his work. Soriano was a known San Lorenzo fan. After his death in 1997, he was buried in the La Chacarita Cemetery in Buenos Aires. His work has since been translated into at least fifteen different languages, and has inspired film directors and producers on fiction and documentary works based on his novels and life-experience.
