You should find Inspector Brega in the Government Dist in the council of six building.. he is all the way in the back - walk forward once you are in the door and you will eventually bump into him...
The reason you are sent to Quayle is to get the quest in the Bridge District to find Haer'Dalis - go to the Five Flagons Inn... go downstairs to watch the cheesy play -hee- and then they will give you the quest...
Hope this helps.
