Horror at Hennepin

From publisher blurb: You head out on the road to fame in fortune but by the end of the day you pull into a roadhouse for dinner and some entertainment. A Bard gives a rousing story about a cursed problem which is quickly dismissed as fable until a loud noise is heard outside... This adventure setting was designed for 5th Edition AD&D for the Filbar Campaign for a party of first level adventurers and DM.
