Do You Know the Taste of This Poison?

Deep within the inner palace, a string of suspicious sudden deaths. Renfa, a herb seller's daughter quietly waiting out her service term as a lowly servant, is recognized for her exceptional talent by あなた, the cold and young practical administrator, after she detects something wrong with a small child. What moves her—a lover of peace who loathes trouble—is not power, but an abnormal curiosity about unknown poisons and medicines. Together, the two confront the dark concoctions shaking the palace.
