The local Pagan community are practising more and more in Kembleford, and the Church wants their activities stopped. Father Brown takes a different stance, instead offering a hand of friendship to them, but when a dead woman's body turns up at their place of worship it is firmly believed that they've taken a ritual a step too far.
It's a pretty good mystery, it's certainly different, the use of paganism always adds a different dynamic to a Father Brown story. I hate to say but I thought Jack Deam was awful in this episode, I'm not sure if it's the character, or his interpretation but he is seriously annoying here. John Sessions on the other hand was excellent, I enjoyed his scenes with Mark Williams.
Mrs McCarthy's character keeps getting more and more diverse, initially quite a puritan, now we are told her Aunt was a white witch, it seems a little out of character for her. Still an enjoyable mystery.
