“Mrs. Shim Is a Killer” by Kang Jiyoung follows Shim Eunok, a widow and mother of two whose husband took his life five years ago following a series of complications with his health. She is now unemployed, hopeless, and ashamed, and dreads going home to the sight of a mailbox overflowing with unpaid bills. We meet her at one of her lowest moments, overwhelmed by despair, where we are reminded that the family had to sell their butchery to pay off the damages of a pub her husband drove into, in what police ruled as suicide.

As fate would have it, Eunok stumbles upon a Help Wanted notice from a private detective agency. She’s all too aware of the worn clothes on her back and the fact that her schooling ended early, and the worry creeps in that they’ll judge her before she even gets a word out. As she pauses outside the building, an older guard gives her a salute that feels strangely knowing. It’s a small, unsettling moment that hints at something bigger already moving around her—something she hasn’t begun to piece together.
The interview shifts from odd to chilling as the interviewer focuses on her experience with knives. And much to her shock, he offers her a job on the spot, leaving her feet frozen to the floor in disbelief. You almost want to scream at her to resist the offer, but that is just before a gold bar is placed on the table, promising quick wealth that could secure her children’s future, if she does the new “job” well.
From there, the novel expands outward, shifting perspectives to reveal the agency’s inner workings and the many lives entangled within it. You are drawn into a layered story that moves between various voices, among them, The Boss, a relentless secret agent, a watchful daughter, and clients whose pain is so deep that revenge feels like their only remaining answer. These voices do not unfold in a straight line, and by taking that form; readers are offered the thrill of assembling the puzzle pieces themselves. Through it all, Eunok remains at the center, not as a cold professional but as a reluctant woman learning to survive inside a world that demands detachment. In that light, as a reader, you might feel forced to root for her even when questioning the morality of her choices, especially when consequential figures from her personal life begin brushing dangerously close to her new reality.
This book will surprise you with how well it balances humor and horror. It moves steadily, allowing tension to build through shifting viewpoints and quiet revelations, as well as unsettling realizations that raise the underlying personal stakes into something that can’t be solved with skill alone. If you enjoy stories that blur the line between dark and playful, or where characters are underestimated only to quietly reinvent themselves in ways that surprise even them, then “Mrs. Shim Is a Killer” by Kang Jiyoung should be your next read!
