K9 and Company

K-9 and Company was a proposed Doctor Who spin-off which apart from this episode shown as a Christmas Special never came to fruition. The title of this episode "A Girl's Best Friend" is set in the fictional village of Moreton Harwood where Sarah and K9 investigate the disappearance of Brendan Richards, the ward of Sarah's Aunt Lavinia in the wake of increasing reports of witchcraft.
