It's the last day of Big Finish-mas, and we end with a Fifth Doctor story and a journey into E-Space...

Doctor Who - Mistfall, written by Andrew Smith, and starring Peter Davison, Janet Fielding, Mark Strickson and Sarah Sutton, is the twelfth of our Big Finishmas titles:

Drawn off-course, the TARDIS passes through a CVE into a closed universe – a hugely improbable event with a tragically obvious cause. In order to escape inescapable E-Space, the Doctor, Nyssa, Tegan and Turlough are forced to venture in the wilds of planet Alzarius.

But they're not the only unwanted visitors to this strange world. A Starliner has landed, captained by Decider Merrion – but why would Merrion risk rousing the Planet that Slept, and the monsters in its marshes?

Mistfall is coming. The Marshmen are coming. But while Nyssa and Turlough find themselves caught in the open, in the hands of fanatics who model themselves on the legendary Outlers, the Doctor and Tegan discover that the supposedly secure Starliner affords them no protection from monsters both within and without...

Doctor Who - Mistfall is one of our main range of Doctor Who stories, and is available for the next 48 hours (until mid-day on the 7th January, UK-time) on Download for £2.99. It also features Jemma Redgrave as a co-star - for fans of her work, check out our UNIT - The New Series range.
