'Doctor Who' gallery: More pics from 'Hide'

The BBC has released another set of images from this weekend’s new Doctor Who episode, ‘Hide’, written by Luther creator Neil Cross.

Clara and the Doctor arrive at Caliburn House, a haunted mansion sat alone on a desolate moor. Within its walls, a ghost hunting Professor and a gifted psychic are searching for the Witch of the Well. Her apparition appears throughout the history of the building, but is she really a ghost? And what is chasing her?
