Someone paid me to assassinate the dragonborn

Im an experienced thug- I have killed countless people and made thousands of septims. When people ask me if it bothers me that i end so many lives, i tell them that whoever i kill must've done something horrible to the person that pays me, and my little girls make it all worth it at the end of a day. If i was a guard i probably couldn't afford my manor.

Anyways, i was at the Bannered Mare, gulping down some Argonian wine, until Ahlam approaches me. She says that Nazeem was brutally beat and robbed by the dragonborn, and he didn't even have to pay a fine because he's the thane of whiterun or something.

As much as i'd like to help this poor widow, no amount of money or goons will make me even look Dovahkiins way. I mean have you even heard what this guy has done? He is somehow the Archmage, A Nightingale, The leader of the thieves guild and a Thane in FOUR holds! He could probably whisper ^{fus ro dah} in my ear silently and i would collapse! So no, lady, i wont do it! Even if you give me 200 gold!!!!

Edit: She offered me 300 gold so i called 2 men to help, imma let you know how it goes
