As Mark Gatiss puts pen to paper for this latest episode of Doctor Who, we have a selection of special offers on his previous work for Big Finish.

You can grab a download of his Main Range story Doctor Who - Invaders From Mars, featuring Paul McGann and India Fisher as the Eighth and Charlotte Pollard at the bargain price of £1.50!

If the Ice Warriors didn’t terrify you enough, or your tastes are more gothic, Mark Gatiss played the scariest vampire of them all, Dracula, last year for Big Finish. You can pick up this dramatic audio adaptation of Bram Stoker’s classic, for £20 on CD or £15 for the download. Try a bite of the trailer below:

For those who are a fan of the Virgin New Adventures of Doctor Who, we have one of Big Finish’s novel adaptations up for grabs, starring Sylvester McCoy and Sophie Aldred as the Seventh Doctor and Ace.

Professor Nightshade - tea time terror for all the family, and the most loved show in Britain. But Professor Nightshade's days are long over, and Edmund Trevithick is now just an unemployed actor in a retirement home, fondly remembering his past.

It's the same through the entire village of Crook Marsham - people are falling prey to their memories. At first harmlessly, and then, the bodies begin to turn up.

The Doctor and Ace arrive on the scene - but, with the Doctor planning his retirement, it may be time for Professor Nightshade to solve one last case.

Doctor Who - Nightshade is available with over half off its normal price, this weekend only! Down to £6 on CD and £5 on download.

Finally, for fans of Bernice Summerfield, there’s Doctor Who - The New Adventures of Bernice Summerfield: The Unbound Universe, which features David Warner as the Doctor, and is just £23 on CD and £20 Download (extra points if you can work out who Mark Gatiss is playing!)

A CD purchase will unlock a download version as a Big Finish exclusive - which you can listen to on the Big Finish App. These titles are also available in Series 10 Week 9 bundles (the CD bundle includes Invaders from Mars download), with free UK postage. These offers only last until midday Monday 12th June, so don’t delay!
