First of all there is no spoiler tag on this topic although there obviously are some. Dace, you should've (and you still can) say that your reply contains spoilers.

Ok, so here's another spoiler below.
Insane, the quest you're currently working on is the first quest for Narlen in thieves' guild. The next quest is the one this topic is about. BTW, it's Splurging Surgeon inn.
