Andreu Nin disappears during the Republican government’s internal crisis, after the leadership of the Workers’ Party of Marxist Unification (POUM) is arrested. His fate remains unknown even to the government’s civilian intelligence services. The novel makes that absence more than a missing-person case: it marks how clandestine detention and factional violence can erase both a political opponent and the evidence needed to account for him.

Background: repression after Barcelona

Nin’s disappearance follows the May 1937 fighting in Barcelona, where Trotskyists and anarchists clashed with forces of the Generalitat and the Republican government. The six days of fighting left more than two hundred dead, all antifascists, and the crisis contributed to Largo Caballero’s fall and Juan Negrín’s rise to the premiership. Before Manuel Arroyo returned from London, the POUM leadership had been detained in reprisal, though no one dared to describe the arrests publicly in those terms.

Nin, the POUM’s leader, had been missing since 18 May. The novel stresses the breadth of the silence around him: even civilian intelligence bodies belonging to the Republican government did not know where he was. His disappearance therefore sits at the intersection of open factional conflict and concealed state violence, rather than appearing as a publicly acknowledged arrest with a traceable legal process.

Madrid: a divided rear and an unknown fate

The crisis in Madrid was more volatile than the bleak picture Negrín had described at the end of May. Nin’s disappearance enraged the city’s small POUM community, which had the backing of many Madrid anarchists. The anarchists were numerous, though fewer than the socialists; the socialists themselves were deeply divided. Socialists and Communists together supported the government in Valencia and Madrid’s Defense Council, but their agreement was limited and incomplete.

The political fragmentation gives the disappearance its immediate force. Nin’s absence could intensify anger among groups already at odds, while the lack of reliable information left those groups unable to distinguish what was known from what was suspected. The episode’s uncertainty is not resolved by a later confirmation in the supplied account; instead, the persistent absence becomes evidence of how little control or transparency the Republican authorities possessed over clandestine detention.

The machinery of disappearance

A later account of a wounded man identified as Rafael Cuesta Sánchez shows the mechanics of concealment that the novel associates with the period. Guards initially took him for a corpse and sent him to the infirmary. When a commander found a credential from the Defense Council’s Public Order Department, a police commissioner ordered that, if Cuesta was dead, he be buried as an unknown person without registration; if alive, he had to be saved without entering a hospital under his own name, lest someone try to kill him again. The commissioner offered no explanation beyond saying that Cuesta was vital to the Republic.

This episode does not establish what happened to Nin, but it clarifies the narrative world in which his disappearance occurs: a person could be hidden from records even while officials claimed to be protecting him, and orders could be enforced without reasons or public accountability. The contrast between a named political leader who vanishes and an injured man whose identity must be suppressed makes disappearance legible as both a threat to life and a method of controlling information.

A pattern of erased identities

The novel later widens the frame to other forms of political disappearance and concealment. At the end of the war, an unknown body is sent to a mass grave at La Almudena Cemetery under the familiar false explanation of cardiac arrest, despite a bullet wound in the neck. The episode belongs to a later setting and does not resolve Nin’s fate; its relevance is the recurring conversion of political violence into an unrecorded death, an anonymous body, or an officially empty explanation.

The account also describes the Argentine dictatorship’s systematic forced disappearances: thousands of people were estimated to have vanished between 1976 and 1982, while clandestine task groups divided the work of abduction, secret detention, torture, execution, disposal of bodies, and the concealment of stolen children’s identities. These later events are distinct from Nin’s wartime disappearance, but the novel’s juxtaposition gives the earlier episode a wider resonance. Across different regimes and decades, disappearance attacks not only the person taken but also the possibility of naming the perpetrators, locating the victim, and preserving a reliable record of what occurred.
