A criminal psychologist investigates a killer while caring for a traumatized child with disturbing similarities.
The story intertwines two timelines through Seonkyeong’s perspective. She navigates the complex psychology of Yi Byeongdo, who demands her attention despite his history of refusal. Simultaneously, she manages the household after Hayeong arrives from the fire that killed her grandparents. The tension rises as Seonkyeong realizes the girl’s behavior mirrors the killer’s past trauma. The narrative structure forces the reader to question the reliability of both the interview subject and the child. Seo uses her background in psychology to explore how abuse manifests in different generations. The plot does not rely on jump scares but on the creeping dread of recognizing patterns. The ending remains ambiguous regarding whether the danger is external or internal to the family unit.
The novel is published by Ecco Press in the United States. It draws on the tradition of psychological horror and criminal profiling fiction. The setting involves Korean characters within a Western publishing context, reflecting global interest in cross-cultural thriller narratives.

Seo effectively leverages her background in psychology to craft a narrative of unsettling parallelism. The interweaving of the serial killer’s interviews with the domestic crisis creates a potent atmosphere of creeping dread. The book excels in its subtle depiction of abusive patterns, avoiding jump scares in favor of psychological realism. It suits readers who appreciate complex character studies and moral ambiguity over action. While the lack of supernatural elements may disappoint some horror purists, the rigorous focus on behavioral analysis offers a distinct and compelling experience for those who enjoy literary suspense.
