We were incredibly pleased with how it went, and the feedback from fans has been overwhelmingly positive. We had over 15,000 fans attend across the weekend, and have had an overwhelming response on email of great customer feedback. The fans particularly loved the Cosplay Showcase Competition, which 600 fans took part in over the weekend.

What were the highlights? The creativity and obvious excitement from fans is always the highlight of an event like this. The fans love the Festival – 600 ticket holders took part in the Cosplay Competition and look AMAZING. It‘s always great to see how dedicated the fans are to the show and how they interact with all the content that was at the event. Many shared their love of the Festival through social media and the response has been fantastic. Other highlights include seeing visitors act with a Dalek coached by Nick Briggs and Barnaby Edwards and being directed by Director Douglas Mackinnon in a scene from Listen. Of course the emotional farewell to Jenna Coleman as she bowed out as Clara was sad but a memory that I’ll take away from the weekend.

Ever since we secured the deal with the Haisman Estate, we’ve been planning to bring back Harold Chorley. He was such a pain in Lethbridge-Stewart’s side in The Web of Fear it was a forgone conclusion that he’d return to give the colonel more grief. His return has been set up throughout the last few books, with hints as to his situation following The Web of Fear. Now we finally get to play it out properly, and Nick has done a great job with him!

I had a great time writing Mutually Assured Domination, taking as my inspiration the Cold War thrillers of John Le Carre and the 1985 BBC Drama Edge of Darkness. I have always loved the Dominators and their sinister robotic servants so it was great to be given the chance to make them live again! My favourite parts of The Dominators has always been the bickering between Rago and Toba and there's some of that in this book, in fact there is great comedy potential in the characters. But I also hope I have presented them as a credible threat and a worthy foe for Lethbridge Stewart. I hope people find my book is to be a good old-fashioned romp – and a wham-bam ending for the first 'season' of Lethbridge-Stewart novels!

In a twist that completely delighted me, (this book) is set in precisely that era: the late ’60s, with the protest movement still at full power and the anti-nuclear ticket a hot one. It even has its own desolate wilderness – Dartmoor. Though of course at the heart of this wasteland stands not the Doctor, but his unofficial deputy on Earth (at least, that’s always the way I used to think of him), and another fine creation of Messrs Haisman and Lincoln, Alistair Gordon Lethbridge-Stewart, better known as ‘the Brigadier’, though for our purposes today he’s still a colonel.”

Since day one of this series I have been mindful that there are certain milestones in Lethbridge-Stewart’s life that need to be dealt with in these books in one way or another. His meeting with Gilmore is one of those. With the approval of Ben Aaronovitch, who created Gilmore back in ’88, and with thanks to Andrew Cartmel (Doctor Who script editor 1987-89), we are finally able to make that happen with our own spin. Hopefully we’ll offer fans a little bit more meet to their meeting. It’s been a real joy bringing these two iconic characters together and letting them play in each other’s sandpits – for one night only!

The Doctor and Clara, with their old friend Rigsy, find themselves in a magical alien world, hidden on a street in the heart of London.

Sheltered within are some of the most fearsome creatures of the universe… and Ashildr (Maisie Williams)! With a death sentence hanging over their heads, not all of the intruders will get out alive.
