This is certainly a must watch for those who like Sherlock style of investigation. All the young actors, 5 of them, who are playing the central characters , have done a marvelous job of bringing out both ,the genuineness of their characters n the multiple layers in the investigation. The prince, his twin brother, his two friends and his young female coroner , remain united inspite of the challenges they faces. Their trust and concern for each other helped us realise the importance and values of sincerity and support. Prince An and Chu Chu had the brain , guts and persistence to follow through every clue and they gave excellent clear explanation for their deductions. Young Jang provided lots of humour and his lady love, Leng, was an awesome fighter who protected the people she cared for. So did , General Zhou,Prince An's twin brother. It was heartwarming to see him fussing over his brother's well being. The plot also makes one realise how people in power can take for granted the position they are in and believe that this position is their right and cling to this comfort zone at whatever cost. The old chief eunuch was an excellent example of this . He shows how power corrupts ,blinds and breeds greed in a person. This show is brainy, well written , well acted and smooth flowing. It is indeed a worthy watch.
