Yuukoku no Moriarty: “Hiiro” no Kenkyuu

A man in a tavern recognizes Moran's dishonesty during a poker game and dares him to a high-stakes match. William takes interest in this encounter. Meanwhile, Louis, overly enthusiastic, dubs the tropical fish under his care "William." Albert and Moran engage in a drinking competition involving wine. John, rather than Sherlock, acts as the detective and demonstrates his notable deductions. Previously unreleased daily research records, absent from the main story, are now made public.
