Thoughts
I particularly liked how the plot focus on the howdunit, which eliminates the sob story that most detective drama tend to have at the end of each episode/season. Even if the lead was not Ohno, I would still watch this drama. Though, a bit more humor and less poker face would be swell.Below, I have compiled a list of the "hints" in each episode's opening.

Opening Scene

The side in which they stood at the opening scene indicates the gender of the criminal in each episode. (No opening scene for episode 10.)

• Robot
• Initials of the criminal's stolen & real name. Not sure if the "I" in "idintity" meant something or a mistake during production.
• 609: The movement shows the dead combo/combination shot. The numbers 09 can be read as "o-ku", which means billion, alluding to cost of the diamonds.
• Airplane that Enomoto gets on.
• Glasses: This is perhaps the best hint. Enomoto takes off his glasses -- Showing his true colors.

Quotes
A beautiful line on freedom and its worth, spoke by Enomoto in the last episode. I particularly like how the author (or screenwriter?) used the word "gomen".

「それで、硝子が越えられたんですか？

復讐を果たし、ダイヤを手に入れて、あなたは開放されたんですか？

僕にはそうは見えません。

前後左右、それから上下まで、

硝子に囲まれているようにみえます。

僕は硝子の箱に閉じ込められるのはごめんです。

たとえ向こう側に行けないとしても自由でいたいんです。 」

"Have you reached the other side of the glass?

After seeking revenge, obtaining the diamonds, are you liberated?

I don't think so.

I see glass entrapping you from all directions.

I refuse to be entrapped.

Even if I can't reach the other side, I would like to to be free."
