Operación Masacre
Rodolfo Walsh
 The novel details the Jose León Suárez massacre, which involved the 1956 capture and shooting of Peronist militants, including rebel leader Juan José Valle. These events followed a 1955 military coup, known as the Revolución Libertadora, which deposed Argentine president Juan Perón and eventually brought the hard-line general Pedro Eugenio Aramburu to power.
