Doctor Who: The Carrionite Curse (Classic Doctors, New Monsters, #2.03)

Katy Bell returns to her Midlands home to find strange goings-on at the buskers fair. A witch trial in the 1980s. A bonfire ready to be lit...

Luckily, a colourful visitor is already investigating, and the local vicar, Katy's dad, is versed in tales of the macabre. Terrifying forces are on the loose, and the town hall holds a secret. There is black magic in the Black Country, and the Doctor has the name of his enemy on the tip of his tongue...

Something wicked this way comes.
