Yup, it's a mystery show with awesome cases and great characters. Too bad almost no one even knows of the series and because of that, it'll probably be hard to track it down (I think?). But it's definitely worth a watch. Each problem is an episode long with, I believe, only one 2 episode case. Like all shows, there are a few episodes that are a little boring, but at the same time there exist a few that are so great and so memorable.
Seriously, give it a watch and join this small club of Master Keaton enthusiasts.
