My favorite Aiba drama (usually I don't finish watching his drama, sorry aiba), the acting of him and his three servants, was also really entertaining, especially during the re-enactment part.

The mystery itself is also very interesting. I could barely guess who the culprit was before Kizoku Tantei explained, which is different from the other detective dramas I've watched. Usually, I can already guess who the culprit is from the start.

I also like Hana's character, at the beginning hhe was a bit annoying, but towards the end of the episode he became one of my favorite characters
