[Alphanor]

I seem to be having some problems with the quests in the Friendly Arm inn. I've accepted the quest from Bentley, but can't find how to enter the basement. I saw in another thread that there's a trapdoor in the kitchen, but nothing is appearing. 
Also, there's a character outside the inn who asks you to speak to him in his house: the house is marked on the map, but I can't find any way to enter it.
