Butter

The cult Japanese bestseller about a female gourmet cook and serial killer, and the journalist intent on cracking her case, inspired by a true story

There are two things that I simply cannot tolerate: feminists and margarine.

Gourmet cook Manako Kajii sits in the Tokyo Detention House convicted of the serial murders of lonely businessmen, whom she is said to have seduced with her delicious home cooking. The case has captured the nation’s imagination, but Kajii refuses to speak with the press, entertaining no visitors. That is until journalist Rika Machida writes a letter asking for her recipe for beef stew, and Kajii can’t resist writing back.

Rika, the only woman in her news office, works late each night, rarely cooking more than ramen. As the visits unfold between her and the steely Kajii, they are closer to a master class in food than journalistic research. Rika hopes this gastronomic exchange will help her soften Kajii, but it seems that Rika might be the one changing. With each meal she eats, something is awakening in her body. Do she and Kajii have more in common than she once thought?

Inspired by the real case of a convicted con woman and serial killer—the “Konkatsu Killer”—Asako Yuzuki’s Butter is a vivid, unsettling exploration of misogyny, obsession, romance, and the transgressive pleasures of food in Japan.
