Think twice before you visit

scary . . .

And where was this infamous character inviting her to here? A dark cave?

A series of rock chambers and sluice gates would allow the sea water to flood the local area at appropriate times. Then, through evaporation, the sea salt would be harvested. 'The local area' being . . . where we live. Dun-de-dun-dun-aargh!
We always said we'd live on a hill. Now we live very slightly below sea level. Anyone want to visit? By 'eck, Sheila was really brave.

But, of course, you can always rely on divine protection round 'ere.
Lovely visit, She. And make sure Lucy eats up all her dinner, just like her Nan. xxx
