It's that time of year again: frantic last minute shopping, swearing at rolls of Sellotape, covering fir trees with bling....and the dragons emerge with a festive folkloric offering that adds a bit of shadow to the season.

This year Jules and Madeleine take a look at the strange relationship between Christmas and witchcraft. If that sounds implausible, stick around - there is a bizarre logic behind it. As with many folkloric traditions, the Christmas witch goes back centuries but some of the modern iterations bring a new level of horror to the tradition. We remember Father Christmas but forget Perchta. We tell stories about St Nicholas but forget St Lucy and her alter Ego, Bloody Lucy. And just who led the wild hunts during Saturnalia and later the twelve days of Christmas? Find out in a special festive episode.
