I love the muted look on the culprit's face when the victim told him the truth.
Anyway, easy case. I watched the anime version of Detective Conan first and this was the first I actually understood everything before Conan started his deduction show. ( In hindsight, every hint was extremely telegraphed).
Also, the only way I figured out what weapon the culprit used for the case was because of Runescape and the obsidian weapon within the game.
