In his controversial 2001 novel, The Guest (Sonnim), Hwang Sok-yong tells the story of elderly Korean American Ryu Yosŏp, who embarks on a journey back to his childhood home in Hwanghae province, now North Korea. At once a spatial, temporal, and psychological return, the novel revisits the early years of the Korean War to unveil the truth behind one of the war’s most horrific crimes: the slaughter of 35,000 Korean civilians in the Shinch’on massacre of 1950. In particular, Hwang examines the arrival of the two “guests” of the title—Christianity and Marxism—during the colonial period and their subsequent role in the violence of Shinch’on. By making visible forms of political agency achieved through the assimilation of these two guests, the novel complicates the ideological binaries that appear to have arrested decolonization of the Korean peninsula. Watson’s article reveals how Hwang’s experimental, multivocal narrative structure rewrites usual historical accounts of the Korean War and division by attending to the spatialized production of regions, nation, state, and diaspora. It offers a rethinking of the congealed ideologies, stories, desires, and topologies of this not-yet-postcolonial peninsular.
