I like the premise of the adventure. I do not feel that the adventure would last four hours. The material presented here requires a DM to provide alot of fiat to make the adventure reach it projected time limit. It can be done though. I felt that there could have been a NPC summary somewhere to describe the NPCs. DMs may find themselves having to add a little here to give the players a bit more role-playing interaction. I will say that the boxed text was enjoyable, especially 'The White Lady' boxed text. Overall, this module provides the framework for a decent adventure. Where it lacks could be filled in fairly quickly with preparation. It does have elements of combat and socializing, which make it worth a purchase.
