Nobody talks about this one. A 1979 mystery special that treats a Lupin heist like a locked-room puzzle instead of spectacle, where every clue actually matters and the solution feels earned instead of pulled from nowhere. The pacing is patient in a way modern anime forgot how to do. If you've ever wanted to watch someone outsmart a problem instead of punch through it, this is built for you.
