Witchcraft comes to Great Slaughter, straight out of the black magic textbook. A burnt body of a woman is found in the woods, she could have been a human sacrifice.
WPC Button is shocked that witches have operated a coven in Great Slaughter. She is shocked to learn that her old school dinner lady Miss Heather Hartwood is a witch.
The dead woman turns out to be Jackie Rice, a gardener. Reverend Mother Adrian wants to banish all devil worshippers from the town. Fifteen years earlier she had banished a witch from the town.
This should had been a darker episode, with parallels to the real life witchcraft trials in England. Instead it tried too hard to be zany and off kilter. Leading to an uneven mix and just feels too silly.
