'''Heather Threadstone''' was the daughter of [[Threadstone (Vampire of the Mind)|Professor Threadstone]] and a [[scientist]] herself, like her father. Like her father, she was a friend of the [[Sixth Doctor]], and accompanied him during the investigation of the [[Dominus Institute]] in [[2016]]. The Doctor helped in her investigation of her missing father and discovered {{Pratt}}'s involvement.  ([[AUDIO]]: ''[[Vampire of the Mind (audio story)|Vampire of the Mind]]'')
