Whispers of Terror is a Big Finish Productions audio drama based on the long-running British science fiction television series Doctor Who.

The Doctor and Peri find themselves in the Museum of Aural Antiquities, where every sound is stored for posterity – from the speeches of Visteen Krane to security service wire taps and interrogation tapes.

But they also find an intruder, mysteriously changed recordings, and a dead body.

Before long the Doctor realises that there is more going on than a simple break-in or murder.

How can he defeat a creature that is made of pure sound?
