Out now is the second part of our 50th anniversary Companion Chronicles trilogy, Doctor Who: The Dying Light.
Doctor Who - The Companion Chronicles: The Dying Light unites Frazer Hines as Jamie and Wendy Padbury as Zoe once more in a new Second Doctor story - but there's a character still hanging around in the aftermath of previous release The Beginning...
The TARDIS materialises on a dying world circling a dying sun, where the Doctor, Jamie and Zoe are welcomed to Sanctuary - an entire monastery carved out of a mountain.
But little here is quite what it seems.
Quadrigger Stoyn has waited through the centuries. And it is time for the Doctor to pay for his first terrible mistake.
Doctor Who - The Companion Chronicles: The Dying Light is available now on CD and download. The concluding part of the trilogy, Luna Romana, is out next month.
Nick and Benji welcome you to the audio awesomeness of Big Finish. There's a big Callan preview, news, emails and so much more. Guest Star: Tom Price (Sergeant Andy Davidson in Torchwood). Drama Tease: The Siege of Big Ben (featuring Jackie Tyler).
