I am currently in the city of Riften in Skyrim. I'm working on the quest A Chance Encounter where I've been asked to steal Madesi's ring out of the locked box in her merchant's stall. This quest initiates contact with the Thieve's Guild so it's important that I finish it.
I'm able to get behind the stall and pick the lock without being detected. When it comes to actually stealing the ring, I'm totally stumped. Even while sneaking, I can't seem to get out of sight when I go in front of the box. There is not looting option when I try and take it from behind. Here's a view of the stall:
I have no idea what I'm supposed to do. Short of chugging an invisibility potion, is there any way to nab this ring without getting caught? I'm sure I'm missing something.
