For Japanese readers, I have been following "Hamamura Nagisa no Keisan Nooto" (Hamamura Nagisa's Calculation Notes), which is a light novel mystery series. Most chapters contain some crime by a math-minded terrorist, and the solutions to the mysteries always involve math. It covers a wide range of topics from simple fractions to Fermat's Last Theorem. It's a wonderful series for people who like math. https://ja.wikipedia.org/wiki/%E6%B5%9C%E6%9D%91%E6%B8%9A%E3%81%AE%E8%A8%88%E7%AE%97%E3%83%8E%E3%83%BC%E3%83%88 https://ja.wikipedia.org/wiki/%E6%B5%9C%E6%9D%91%E6%B8%9A%E3...
