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, and translated by Polly Barton.







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





Gourmet cook Manako Kajii sits in Tokyo Detention Centre convicted of the serial murders of lonely businessmen, who she is said to have seduced with her delicious home cooking. The case has captured the nations imagination but Kajii refuses to speak with the press. That is, until journalist Rika Machida writes a letter asking for her recipe for beef stew and Kajii cant 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 masterclass in food than journalistic research. Rika hopes this gastronomic exchange will help her soften Kajii but it seems that she might be the one changing. With each meal she eats, something is awakening in her body. Might she and Kaji have more in common than she once thought?



Inspired by the real case of the convicted con woman and serial killer, 'The Konkatsu Killer', Asako Yuzukis Butter is a vivid, gripping exploration of misogyny, obsession and the transgressive pleasures of food in Japan.
