Trail of the White Worm (audio story)

Trail of the White Worm was the fifth story in the first series of the Fourth Doctor Adventures, produced by Big Finish Productions. It was written by Alan Barnes and featured Tom Baker as the Fourth Doctor and Louise Jameson as Leela.

It offered an explanation as to why looked different between the version played by Peter Pratt and the one played by Geoffrey Beevers, revealing that the Master managed to partially reverse his deformity after absorbing some energy from the Eye of Harmony, transitioning him from a more skeletal appearance to a slightly rejuvenated appearance in comparison.

Synopsis
The legend dates back to Roman times, at least: a great White Worm, as wide as a man, slithers out of the rocks of the Dark Peak Gap to take animals, sometimes even children, for its food.

When the Doctor and Leela arrive in the wilds of Derbyshire, only to get caught up in the hunt for a missing girl, they soon discover that the legend of the Worm is very much alive — even now, in 1979.

Worse still, it seems that the Doctor isn't the only renegade Time Lord on the trail of this deadly and mysterious Worm...
