Borges’s writing partnership with Bioy Casares was long-lasting and fruitful, producing a unique narrative voice and several pseudo–authors. Two of these are Bustos Domecq and Isidro Parodi –specialists in crime detection and detective fiction. Bioy and Borges collaborated as editors and compilers – of anthologies, prologues, glosses, and translations. Their attacks on nationalist and populist politics were especially virulent in the period 1942-1947, with General Perón the main target. ’La fuerza del monstruo’ (1947) is a powerful condemnation of the abuse of power and could not be published until his removal from power in 1955. A key feature of ’La fiesta...’ is its linguistic texture, constructing a carnival atmosphere.
