Midsommer Murders had some Druids on on their show on Wednesday 21st September. You could still see it on the catch up TV thing until Wednesday 28th.
It starts with a murdered body found in a stone circle (They are so lucky in Midsommer-shire to have an ancient stone circle as well as everything else!)
The druids themselves were not sympathetic characters in the drama, but they did put over two different views of druidry. There is talk of ley lines and power and the awen, and plenty of scepticism. Obviously you're DCI Barbaby is a sceptic
I won't tell you who does the murder here so as not to spoil it for you.
