Here's an alternative ...
As it happens, the Devil doesn't figure at all in the legends associated with Crazywell. To make up for it, there's the 'Witch of Sheepstor' to deal with and an 'Oracle' in the pool, that may or may not be the ghostly voice that predicts who will be the next person of Wakhampton Parish to die. And of course, like so many other variants, the pool is bottomless. I hesitate to say that none of this is true ... but not for long. None of this is true.
Except for the bit about a witch.
