The story of twin brothers (Ji Sung) tracking down the truth behind a murder 22 years ago. Prosecutor Song Soo Hyun searches for the real culprit to clear his father's name for killing his stepfather, and his younger brother, a writer Ha Woo Shin, searches for the evidence of the murder, Adamas.

Adamas has all the elements that makes it an intriguing mystery thriller; greed, lies, conspiracy, shady characters, etc. Though I was not sold with the lack of urgency in the premise, of why now after 22 years they need to investigate this case, I was curious to find out what’s behind the mysterious mansion people and about Adamas.

I had a great time watching the high-class cinematography, editing and Ji Sung. As always, he’s a captivating performer. Playing the twins, an angry-bird-but-soft-at-heart prosecutor Song Soo Hyun and a calm & collected novelist, Ha Woo Sin, who gains entry to the museum-like mansion of a CEO to write his biography, while carrying his own personal agenda; looking for the diamond-crafted weapon Adamas. Both of them have their own quirks and were really fun to watch! :)

The story unfolds slowly, but the twists maintain a good momentum. Unfortunately for me, it wasn’t satisfactory that the later part focuses too much on the villains. The ending could’ve been more conclusive as well. Regardless, Adamas is cool, stylish, plenty of ulterior motives and power play.
