This chapter argues that Samuel Beckett’s plays function as a kind of fulcrum in a theatrical history of staging and thematising surveillance, extending from Dion Boucicault’s The Octoroon (1859) through Augusta Gregory’s Spreading the News (1904), to Enda Walsh’s Arlington (2016) and David Lloyd’s The Press (2009) and The Pact (2021). Surveillance agencies rely heavily on technology to gather information, but depend on human beings to store, order, and interpret it, and dramatic narratives exploit inconsistencies and injustices arising from slippages between data and its application. Boucicault, Gregory, Walsh, and Lloyd are counterpointed to Beckett’s Waiting for Godot, Endgame, Catastrophe, and What Where, which theatricalise the structuring influence of monitoring and scrutiny on the texture of Irish social experience, personal and public. Once classified in an archive or record, or interpreted in policy and implemented in practice, ‘intelligence’ plays out less as a function of rigorous analysis than ideological determination.
