I'm stuck on the thieves guild special job in Windhelm, the Summerset Shadows quest. I need to get leverage on Niranye so she'll tell me where Linwe is, because I can't persuade her. I've found the hidden basemant in her house but it has a master lock. I can't pick a master lock. I've pick pocketed both keys she had on her, and neither of them fit it.

Is there no other way I can get in there?

Thanks.

Keep trying, master locks really aren't that hard. Just stock up on picks.
