John Hurt returns as the War Doctor in September 2016, in three full cast audio plays from Big Finish productions. Doctor Who - The War Doctor 3: Agents of Chaos is the third volume in the ongoing saga, in which the War Doctor and Cardinal Ollistra (Jacqueline Pearce) are thrown deeper into the Time War.

The set opens with The Shadow Vortex by David Llewellyn, in which the Time Lords have detected that their quantum shield protecting Earth has been breached by the Daleks, and the War Doctor is sent to Berlin 1961, at the height of the Cold War, to investigate. There he finds that the Daleks have their own agent on the scene… That agent is played by Neve McIntosh, best known to Doctor Who fans as Madame Vastra of the Paternoster Gang, while the cast also includes Honeysuckle Weeks as Heleyna.

‘I was given a very open brief: Send the War Doctor to Earth,’ says David. ‘So then I started thinking, "Where on Earth (literally) can I picture the War Doctor?" and the first image that came to mind was Berlin's Brandenburg Gate in the early '60s - checkpoints in place, the boundary between East and West. Time War meets Cold War. Then I pictured a Dalek saucer landing right in front of it. Then I pictured the skies above Berlin swarming with Daleks. Then I got really, really excited and I started to write.’

In The Eternity Cage by Andrew Smith, the Sontarans continue their campaign to join the Time War - while the Time Lords and the Daleks refuse to allow them to join in. This may change, however, when the Sontarans score a victory over both sides…

The story will be Andrew's second set in Time War after the upcoming release of The Sontaran Ordeal in Doctor Who: Classic Doctors, New Monsters Volume 1.

Dan Starkey (also known for playing the Paternoster Gang’s butler Strax) is the Sontarans, while Josh Bolt (Last Tango in Halifax, Benidorm) plays Kalan.

‘I was asked to write a story taking for its inspiration Alistair MacLean’s Where Eagles Dare,’ says Andrew. ‘So we have an apparently impenetrable fortress on a mountaintop, and the Doctor leading an elite group on a rescue mission. But instead of the German army trying to stop them, it’s Sontarans! With the Daleks not far away either.’

The fate of Gallifrey hangs in the balance in Eye of Harmony by Ken Bentley, in which the Daleks gain the upper hand, while the Doctor and his allies fight to stay alive against all odds.

‘I grew up watching war films,’ says Ken. ‘They were a staple of weekend viewing when I was a boy, so it was great to have the opportunity to explore the genre in Doctor Who, where we generally avoid anything too dark. But even more exciting is the fact that I've written a play for John Hurt. JOHN HURT!! If you'd told me that might happen when I first started working for Big Finish I wouldn't have believed you.’

The box-set also introduces a new player into the Time War - the Dalek Time Strategist, who is voiced, as with the Daleks, by Nicholas Briggs.

‘At the end of Dark Eyes, and the defeat of the Dalek Time Controller, it was hinted that a new 'Time Strategist' would be created in its wake…’ explains script editor Matt Fitton.

‘Daleks never go to war without a plan, and a Time War needs a special kind of planner, capable of viewing the field of conflict through four dimensions and beyond. This is the Dalek Time Strategist: a time-sensitive war-leader, utterly dedicated to achieving Dalek victory over the Time Lords by any means it can.’
