This might be a glitch in the game but I am having trouble finding the butler Shum gro-Yarug in the Skingrad Castle. I need to find him in order to get a job to get to Theranis in the dungeon. He has a book that the Thieves Guild wants. I have tried to sneak into the dungeon with no luck. I have also tried to find him in town. If you talk to a Skingrad Guard they tell you that Shum gro-Yarug spend most of his time at the castle but he goes to the West Weald Inn at ten and the Colovian Trader at noon. I have waited at both spots for him numerous times and the correct times and he never shows up. I cannot advance in the Thieves Guild until I pass this quest. Any help on how to find the butler or maybe another way of completing the quest without him? Where is the back way into the dungeon? Also, if you get arrested and pick the lock to complete this quest how do you get your equipment back?
