Seo Se-hyun is one of Korea’s most brilliant forensic pathologists, but behind her cold precision lies a horrifying secret: she is the daughter of Yoon Jo-gyun, a serial killer known as “the Tailor,” who regarded murder as art. When a body bearing his unmistakable signature appears on her autopsy table, Se-hyun realizes that the father she believed dead for twenty years has returned. Fearing that her past will be exposed, she begins a dangerous hunt to find him before the police do. Meanwhile, relentless detective Jung-hyun follows the trail of murders and grows increasingly suspicious of her. As hunter and prey become impossible to distinguish, Se-hyun must confront whether she is chasing her father—or inheriting his madness. A hard-edged psychological crime thriller where past and present, justice and obsession collide.
