On the surface, The Grimpen Affair is a FREE 1970s British folk horror tabletop role playing game built from the Department 23 core rulebook. It is a single adventure that should take 4-5 people an afternoon to complete.

But that’s not the whole story.

Somewhere in the wilds of the UK, the only physical copy of the Department 23 rulebook has been hidden. It will never be reprinted. It will never be recreated.

The only way to get it is to complete the real-world treasure hunt we have concealed inside The Grimpen Affair. Every clue you need is embedded in the game itself. If you find it first, you can have it. Along with its publishing rights.

The only way to get your hands on a copy of The Grimpen Affair is to join our mailing list. We will send you your FREE PDF copy when it has been completed.

We don’t spam. We only send out messages to our mailing list on a Solstice or an Equinox, 1-2 times a year. Read our privacy policy.
