I wasn't so happy with the drama, so it took me some time to finally watch the special, but after a few minutes I knew that I should have done so earlier. The story of the special is way better than any of the cases in the drama. The case is presented to the viewer in little pieces and just Kageyama is able to figure out how they are connected with each other. I had no idea how to link all the little happenings (although I must say I am quite stupid when it comes to solving mystery^^°) I absolutely LOVE the acting of the two main actors. Sho is wonderful in acting as a butler but also when he accuses his mistress for being stupid. Keiko acts wonderfully as the heir that has to take all of Kageyama's bratty remarks and I cracked up so much about her acting when she was being drunk. Also, Kazamatsuri makes me laugh all the time. His acting his hilarious and he fits the role so wonderful!!! It's a funny special with a detective story and the mix of humor and mystery is just right. It does not get boring and on the other hand there are lots of moments to make you laugh. If you feel like watching a detective drama that isn't too serious, I suggest you give this one a chance! You won't regret it!
