On many of the houses round here – particularly the older ones – you’ll find strange, flat stones protruding from the eaves at each corner of the building.
They’re witch stones – set there deliberately so that passing witches will find a place to rest. The theory is that the witches will be so grateful, they’ll refrain from casting dark spells on the inhabitants within.
In all the years we’ve lived here, I’ve yet to see a resting witch. But then they probably land while I’m asleep.
