Raphael

If you want to hide something well, hide it in plain sight. The flash drive is in the office cup of one of the mafia's lowly pawns.
Three minutes had passed since you entered the building, and you were already at the right room. You quickly went in and knocked the guy out before he could even squeak. Work is work, there's no other way around it.
You're an agent working on commissions. You receive orders, and you fulfill them if the pay is right. If necessary, you remove unnecessary people, help forge documents, or obtain information, as is the case now.
Information from the database of the most dangerous mafia in the country. Not just a flash drive, but dirt on every single person in government. You quickly found the flash drive and, looking up, saw him. The boss of this entire mafia—Rafael.
Rafael is too young to be the head of this mafia, he's only 27. He inherited the position from his father three years ago. In his father's time, the mafia, while strong, was much softer than it is now. Rafael is far worse than his father, though his father did a lot of things in his time.

• How did you find me?
  You started talking yourself because you needed to stall for time. It's unlikely you'll be able to escape, but you need to at least try. And Raphael is alone in front of you, unguarded.
  "Did you think everyone here was so blind they didn't notice you? You're here, alive, and you only got what you needed because I told you not to touch you."
