In colonial-era Korea, a poor Korean boy whose mother does laundry for an American missionary family picks up a ball near their compound. The missionaries' son beats him badly. To hide the assault, the family's mission hospital kills the boy with a lethal injection instead of treating him, and his mother learns that the people who claimed to serve Koreans murdered her child.
The novella takes the most visibly charitable parts of the American presence in Korea, the church, the mission school and above all the hospital, and makes them the direct means of the crime. Its effect is that every past kindness from the enemy becomes retroactive proof of deeper cunning. Evidence of goodwill cannot disprove the hostile image because the story has already made goodwill part of the threat.
The Americans are not villains because of capitalism or class position, as orthodox Marxist fiction would require. They are presented as innately and bodily vicious, scavenging beasts whose cruelty extends to their own children. Hostility grounded in the enemy's supposed essence cannot be ended by a change of policy or system, which makes it permanent and usable by the regime in every era.
The novella was written in 1951, during the Korean War, but set decades earlier, when Japan was the actual colonial ruler. Setting it there moves the national enemy's role from Japan onto Americans. This makes American malice seem timeless rather than a product of the war, and the helpless Korean child victim casts the nation as pure, childlike innocence preyed upon by outsiders.
