This chapter introduces the themes of the book by providing a historical and theoretical overview of the increasing invisibility of the modern abattoir and the animals slaughtered within. Relying on a broad selection of theorists to cover physical concealment as well as psychological avoidance of abattoirs, the chapter eventually turns to Michel Foucault’s concept of the heterotopia. The slaughterhouse as a heterotopia creates the illusion that the rest of society is free from the violence and the animals that are found within, and which deviate from society’s purported norms. The chapter proposes that literature can help lift the abattoir out of invisibility by arguing that in fiction, what may be conceived as hidden or inconsequential space in the real world can become place as its perceived neutrality and liminality are eroded and it is (re)connected with values, emotions, and living presences. The chapter ends with a brief description of the other chapters of the book.
