SYNOPSIS: A mysterious murder in the Blue House convinced Tae-young to take part of the investigation team of Detective So. May they have different approach in handling the evidences but Tae-young's instinct didn't fail her expectations.

It seems like the case was professionally done and well thought which led them to a suspicion that somebody in the Blue House could have done it. Eventually, more and more people got involved in the case. The president's security became tighter as he may be the next target. But to everyone's surprise, a past personal grudge has become the key to all the murders.

REVIEWS: Although there are a lot of characters in the story and it made me confused more than ever (by the time I was able to remember their names, the show is almost over!), I still liked the story. Aside from their realistic portrayal, the way the story was presented has kept my curiosity up to the last moment.

I like how the detectives go into the mind of the murderer to solve the case. It made the approach unique and relating it to other cases is misleading. I didn't even try predicting the end of it because I know, I'll be proven wrong.

So far, this is the best mini series I've seen. It's as good as the other "investigatory" shows here in the US (CSI, Law and Order).
