I ran this adventure for my group this week, and everyone had a blast. The adventure has a nice, strong hook that will pull the players into the investigation easily, even if they don't use the pregenerated characters provided (we didn't). The most obvious lines of investigation are covered, giving the GM a good deal of material to work with. The climactic combat against the Nussknackers in the pie factory was brutal! I provided one per character, and there were times when I thought someone might go down. In hindsight, I'd suggest one fewer Nussknacker than the number of PCs, allowing the PCs to gang up on them.
