Korean Drama "Crime Puzzle" is a dark tale of a deep secret.

The drama starts off on a mysterious note, with the main case being introduced. And truly, there were really dark moments, twists, and intriguing scenes as the mystery was unfolded. However, things were bleak after the first episodes. It seemed like things were happening a bit on the overtone in order to bring out the shocking factor rather than aid the plot. In addition, the story kept ending characters, getting more and more complicated and confusing.

On the other hand, the performances were pretty great, especially by the main leads.

So, overall, 3.5 out of 10.
