Neoreul Gieokhae

The son of a murdered Police psychologist returns from America after many years away after receiving a strange card. He ends up helping a small police team which includes a female detective with her own tragedy which is linked to his. Together they investigate current murders but also find more information about the suspicious deaths of their parents, and even though their relationship starts frostily their common bond draws them together. It has a great cast including, Seo In-guk, Jang Na-ra, Choi Won-young and Park Bo-gum who along with the rest of the cast do a sterling job. The plot idea is interesting and draws you in with the different cases but sadly I have taken a point off as although I occasionally like an open ended ending this series just seems to fizzle out as the scriptwriters seemed to write themselves into a corner.
