I watched this show purely because I love the serial killer genre. I was surprised how this good was this series. Shi Mok inability to feel emotion makes him a decisive attorney who is able to see things as it is without being skewed. His very uncanny first encounter with Lieutenant Han started off on the wrong foot but they shared such a bond later. She always believed in him and he always trusted her. There is no romance but there is definitely something between them.

Shin Hye Sun plays a young attorney who is under his wing at prosecution office. She does not know about his inability to feel and she keeps trying to impress him but he keeps her at bay. Eventually when tragedy strike, Shi Mok does feel he could have done more for Eun Soon and finds her killer.

The plot is engaging and keeps you guessing. Ultimately the truth comes out. Watch season 2 as well.
