Unusual in that it's only 6 episodes, and the conclusion wrap-up is only minutes long. Usually these dramas last 12 or 16 episodes with a full hour devoted to what happens to each character. Here this was extremely abbreviated. The main story drops several hints pointing in the right direction to figure out who was behind the crimes without giving anything away. The separate arc involving the two detectives is particularly well done and arrives at a satisfactory conclusion. Of course, rewatch potential is for following closely the early hints leading to the conclusion. The best measure of a series is the urgency felt to watch the next episode and I found myself looking forward to each next episode.
