A friend asked me to run a one-shot for his birthday, and we happened to celebrate the weekend before Halloween. I did some digging and found this module. The birthday celebrant and the rest of our group are glad that I did! This adventure is appropriately creepy without going too far. There's a moderate amount of body horror, but it relies mostly on macabre imagry and building tension. The players particularly enjoyed the last scene, and not knowing what was the truth and what was a lie. I watched the players squirm, wondering which path to follow. We completed the adventure in about 4.5 hours, which is just right for a one-shot.

If you're looking for a DCC adventure to run on Halloween, I recommend The Sinister Sutures of the Sempstress!
