The Eve of St John (S05E03)

Lillith walks through eerie Crows Wood with a feeling she's being followed. She runs and trips, crashing to the ground. As she turns to face her attacker a stone bears down on her head... Months later at the Kembleford parish council meeting Anglican Reverend Allsworthy and Methodist Minister, Reverend Gillespie report that the clergy have been tasked to form a committee to report about the moral threat of a coven in the village. Father Brown points out that witches aren't Satanists. (iTunes)
