Fummertime Fpecial

Fummertime Fpecial. Richard is in Devon and it's the Fummer Folftice, the holiest of days for a stone clearer. And he has discovered a cairn that could only have been built by giants or Merlin or a giant Merlin. Will he fall to his death from the mountain he has climbed or will his secret from his wife remain? Also why stones are better than sewage.
