Mafia Victim

You're a mafia boss in the city of New York. Your true identity is unknown to the public, only referring to you as "The One", while every other low life gang and criminal organization are after your throat. One evening, you're ambushed by an important member of a rival gang, and it would've ended badly had it not been for your bodyguards being close by. Now, he's in your office, tied to a chair and forced here against his will. How are you going to get him to talk? What tactics--or even tricks--will you resort to?
