To secure her bid, Pernell hired Amber Dent and Goff Fotherill to break into the Museum of Aural Antiquities to alter recordings of Krane's speeches to make them seem supportive of Pernell, and forge a recording of Krane giving a speech naming her as his running mate. When Pernell found out that Krane had survived as a creature of pure sound, she tortured it to find out what it had been up to.
Pernell's bid for power was thwarted by the Sixth Doctor, who had her broadcast blocked, then worked with Krane to have Pernell's crimes exposed on the air. Pernell fled, but Krane manifested itself as a recorded message in her car phone, causing an automobile accident that killed her. (AUDIO: Whispers of Terror)
