Cobwebs (audio story)

Cobwebs was the one hundred and thirty-sixth monthly Doctor Who audio story produced by Big Finish Productions. Released in 2010, it began the first season of Fifth Doctor stories for that year. It was the first new story to feature stars Peter Davison, Sarah Sutton, Janet Fielding and Mark Strickson since TV: Terminus in 1983, thus beginning a "series" of 12 audio dramas for that TARDIS team across four years, finally reaching a conclusion with AUDIO: Prisoners of Fate in 2013.

Publisher's summary
"You know what cobwebs mean. Spiders..."

In search of a cure for a sickness that's so far claimed six billion lives, scientist Nyssa arrives at an abandoned gene-tech facility on the toxic planet Helheim. 'Hellhole', more like.

Nyssa's not alone. The TARDIS has also been drawn to the Helheim base — and in its cobweb-coated corridors, she soon runs into the Doctor, Tegan and Turlough, her travelling companions of half a century past. But who, or what, has engineered this strange reunion? The Black Guardian, perhaps?

The answer's here, in the dark. With the Cractids. In the cobwebs.
