Character: Chris Koller

Undercover is like to live in purgatory. Your life ends, and though you're still walking, breathing and talking - in fact, it's not you. And the longer it lasts, the harder it is to remember who you really are. I was the youngest of seven children, six boys and my sister who had everything she wanted. My life consisted of clothes and a queue to the toilet. Private life? Sure! All of you know. It was impossible to keep a secret or to be left alone. I'd give my left arm to be back for Sunday dinner with his family.

He's a very cool guy, okay?
- I understand.
- No, no, no, listen to me, it's Hugh Killian, he's the boss, the real. This nail look can.
- I said I understood.
Whatever happens - don't ask questions, don't paint me in a bad light. What he didn't say, "Yes, sir", "Well, sir", "Can I kiss your ass sir?".

- If I ask too many questions - they have to calculate.
- You talk like a COP, start thinking like a criminal. What will you do gangster, if his gang went on a case without him?
- Will try to join in...
- Here and try.

For a COP in Chicago most pleasant, the fact that he has a lot of friends. But if you work undercover, like me, the whole day pretending your enemies are your friends and Vice versa. This is enough to confuse who is who.
