Can anybody help me with this quest? I have gotten far enough into it,
but when I went to the Merchant's Quarter, entered his home, and interrogated him, he ran off, and his house is now locked. I have been stuck on this quest for ages now, and I got so frustrated, I just had to get help on a walkthrough. It told me that there is a key to one of his doors behind his house, but I walked all the way around it, I even searched a good few feet outwards from his house, but I could not find the key anywhere. Holding ALT is a good way to spot items, but I did this, and STILL could not find it.

Does anyone know where to find this key? Or if not, can anyone help me solve this stupid quest! I've been long enough at it as it is!!!
