The novel is of course set in the 1950s and is of course semi-fictional. The tension between different nationalities is explored through the soap operas written by Pedro Camacho and the way that he reflects his growing lunacy in the scripts he produces. Gradually, the villains of his work are all Argentines or Peruvians who show themselves to be Argentines, and as time goes by, Camacho's diatribe against Argentina continues, in spite of official protests. Tensions between the different countries in South America are therefore reflected in this witty and amusing story.
Of course, there are nationalistic tensions between the different countries in South America, especially between those that fought wars during the struggle for independence and the subsequent years. This is true, however, for any location. The countries in Europe for example have nationalistic conflicts. This novel accurately reflects the kind of tensions that existed between these different countries in the 1950s but does so in a humorous way.
