Gantman

From Tardis Wiki, the free Doctor Who reference

Gantman was the blind curator of the Museum of Aural Antiquities. After Visteen Krane's death, he and Miles Napton researched the actor's work in preparation for a tribute broadcast. After meeting the Sixth Doctor, he discovered that recordings of Krane's speeches had been altered, which led to the discovery of Krane's new existence as a creature of pure sound, and the truth behind Krane's supposed suicide. After Beth Pernell's crimes were exposed, Krane decided to continue working with Gantman in the Museum. (AUDIO: Whispers of Terror)
