The Mutant Strain is a debilitating disease that turns the already fearsome Daleks into a mindless zombie-like mob. It melts their brains and causes them to rampage across unsuspecting planets, devouring everything in their path.
Earth has not escaped their machinations and when the Doctor and his companion Nyssa land there in the 43rd Century they find only a handful of human survivors still fighting. Can they prevent this new mutant strain from destroying the universe? And why is the Dalek leader trying to drag the TARDIS and its inhabitants to a specific place in time?
This is the third of four Big Finish MP3 audiobooks in the Dalek Empire series and it’s well scripted with strong performances by the ensemble cast. There are even a few nods to well-known episodes in the BBC Drama TV series for diehard fans to spot.
Voice of the Daleks and writer Nicholas Briggs weaves a storyline that revolves around a time paradox and visits a variety of settings in space and time. Peter Davison turns in a convincing performance as the fifth Doctor and Sarah Sutton as companion Nyssa is given plenty of airtime, which she makes the most of in this her first encounter with the Daleks.
