Excellent TV drama, with a very good story line and lots of suspense in every episode. The leading actors & actresses were outstanding ably supported by the whole cast. I have to make special mention of The lead actor playing D o Chang and also the young girl/lady playing Eun Hye.
It's one of those dramas where you are impatient to see the next installment. I think the whole crew should be congratulated including the subtitle team.
If I have one criticism, it is the same as I have with all the other police dramas, in that why do the police shout at each other so much?
