Someone posted a link to an archive.org page that had the entire series of Ninzaburo Furuhata and I was looking for something new to watch and have decided I'm gonna watch some on a whim.
It's described as "Japanese Columbo" and while it's a Howcatchem like Columbo, you can definitely feel the fact that these are hour block episodes instead of the feature length episodes like Columbo. Feels much more like they need to get the plot beats out faster but I don't think it's bad so far. Just different.
