I also had an idea to write a couple of scenes to show what our other regulars were up to while the Brigadier was enjoying Christmas with Sally. And after writing a couple of scenes, a new thought came to me. Wouldn’t it be fun to get as many of our authors involved as possible? I sent out an email, asking for those free to send me a scene, and many responded. Bit by bit the story became longer.”

Back in 2004 I was lucky enough to write for the older Brigadier in Big Finish’s UNIT series. That was an absolute joy. It was an older, wiser but always resolute Brig. Passing years hadn’t diminished his sense of duty or his willingness to risk everything to do what needed doing and do what was right. Writing those scripts was as big a buzz for me as writing for the Doctor. Hearing Nick be complimentary about how we had handled the Brig was one of the happiest moments of my career. Writing a younger version of the Brigadier was something I had pondered, but I didn’t see how I could do it… until news of the Lethbridge-Stewart books came along. When I had the chance to pitch I jumped at it, just for the chance to spend some time with a character who feels like an old friend.

I wanted the book to start with a bang – and so we go straight into the Brig being sent to jail. From there… well, life inside Britain’s prison system wasn’t easy. I’d read about Wormwood Scrubs having been used as a military installation during WW2 and that helped me shape the story and plan how it would unfold. Using the Scrubs made me think of TV and films from the ‘60s and ‘70s that had a real edge. McVicar, Get Carter, Target, The Long Good Friday… suddenly the Brig in jail had some edge, and it was the kind of situation we’d never seen him in before. But he’s clever and he’s resourceful… the Brigadier isn’t Colonel Blimp. He’s a damned good soldier, and he’s a dangerous man in the right situation. I hope that’s the Brig you see in this book. As an outline it went through a few revisions, as most books do. But through the writing and the rewriting, the joy at the heart of it is the Brigadier having new adventures. Taking this wonderful character, putting him in situations he needs to resolve and writing dialogue people will read in Nick’s wonderful, rich voice… that’s an honour and a pleasure. Nick and the Brigadier? Splendid fellows, both of them.

This was a fun story to break. The idea of Lethbridge-Stewart serving time in prison came from Shaun; it was of the earlier ideas we discussed. I personally wanted to bring back both Captain Knight and Colonel Pemberton, who have both been mentioned several times in the series. Indeed both have appeared in some of our short stories, so it was nice to bring them into the novels properly. I approached Iain after he was recommended by a friend, although I was aware of his work I had forgotten he’d written for the Brigadier back in 2004. Iain was up for it, and took on board the small ‘shopping list’, building a very solid story from the initial ideas.

I thought it would be great idea putting Lethbridge-Stewart in prison, so it was a lot of fun to finally read the book (by the time I read them, at the formatting stage, these books are fully written). It was just as I hoped it would be. It combines the tough storytelling of The Sweeney, with comedy elements of Porridge. Iain has really done a fantastic job on this book, bringing some much-needed comedy touches to the Brigadier’s time inside.

I really enjoyed bringing Captain Knight to the fore, as I particularly like the performances that actor Ralph Watson brought to both The Web of Fear and Horror of Fang Rock, and he deserves such a homage. Andy knows my strength, and gave me a brief that really brings out the best in me.

I first met Sharon via the wonderful world of social media back in, I think, 2009. I was very impressed with her work, and soon enlisted her for my Space: 1889 & Beyond series. Her work ethic was proven to me when a novella fell through at the last minute and she agreed to co-author a replacement with me – which we did, in only two weeks! Sharon’s first drafts are often better than a lot of published works out there, and from the off I told her that I would get her writing for the Lethbridge-Stewart series. She resisted for all of five minutes.

I've written for and with Andy before with great success, so I was not entirely surprised when he got in contact about his latest project. For one thing, he'd been 'hinting' for some time that he wanted to rope me in and Andy isn't someone who understands no as an answer.Whenever I hear from Andy, I never know whether to cheer or groan. All those who write novels for well-known television shows now have my utmost respect. Some find it easy; for others the experience feels difficult and involves a lot of angst. I'm one of those worriers. Despite the responsibility, Andy has dragged me into incredible worlds and stories that are part of history and there's no way not to be grateful for that.Invariably the experience of writing for Lethbridge-Stewart was, for me, daunting, exciting, fun, and adventurous…a bit like the character himself.

Sharon was an unknown quantity for me, but I knew that Andy had worked with her before, so I was more than happy to see what she’d come up with. Having read her short story, and looked up her other work, I now believe she’s going to be a wonderful addition to our stable of authors on this series.

I adore working with Candy Jar, and their cover briefs are always so specific, but this one was rather ambiguous as there were several elements that I could have used on the cover. I decided to concentrate on the alien of the piece.One passage of the story mentioned its burning eyes. Using a combination of traditional drawing and then colourisation in Photoshop (to really get the blazing eyes right), this is what I came up with.And I'm pleased to say everyone loved it.

I was fielding around for new authors to bring to the range; authors familiar with Doctor Who but who haven’t written in that universe for a while. A couple of people, including Gary Russell, suggested Simon A Forward as someone who would ‘get’ the series and is very reliable. So, never one to ignore advice of those I (sometimes) admire, I contacted Simon.

As Al Pacino says in The Godfather Part III, ‘Just when I thought I was out, they pull me back in.’ When I was asked to write for the Lethbridge-Stewart range, I was a little hesitant. I wasn’t sure I wanted to return to writing anything Doctor Who-related. I’d moved on in my writing and – much as this may horrify some – I’d grown a little tired of Doctor Who. It was originally quite a different proposition to the finished book that has since emerged, but that process of development and working with Andy was part of the appeal that drew me in and cemented my commitment to the project. Add to that the fact that my (still ongoing) rewatch of Doctor Who took me through The Web Of Fear and The Invasion while I was right in the heart of writing this early Brigadier adventure, and the whole thing seemed like providence. And here I was, with the opportunity to write Anne Travers too. Bonus!

Captain Bugayev is already part of the Doctor Who book universe and it was a fascinating process to explore and contrast the two different approaches and attitudes of the leading military officers, especially two I knew so well. One (Lethbridge-Stewart) courtesy of having grown up with him as such a presence in my Saturday teatime viewing, one through having created him for my Doctor Who novel, Emotional Chemistry.

When Simon first suggested Atlantis I wasn't entirely convinced, knowing that its fate had been mentioned three times in Doctor Who (which fans often view as contradictory, but aren’t really), and in the latter Lethbridge-Stewart was present – if not at the event, then he certainly heard about it. But Simon set my fears at ease and presented a unique idea about how his Atlantis would fit perfectly, without contradiction or any need to have seen the television stories.

The story was initially going to be something else and developed over time and discussions with the editor. One of the things I wanted to do was to take the Fifth Operational Corps somewhere international, as a precursor to UNIT (even though UNIT operated in the UK on our TV screens, they ranged much further in my young imagination) and place them on a wider stage. The Atlantean connection suggested itself from a combination of that aim and from an old story idea of mine that fit the bill well. There was also a sense of, if I was going to write something Who-related, then Atlantis has been as recurring a feature of the show as some returning guest actors. Readers will be sure to spot a liberal sprinkling of homage within the novel and that’s born of the same desire.

Blood Of Atlantis – the difficult second album! I’d had a lot of positive feedback on my first cover, The Showstoppers, but the more I looked at it the less I liked it, and the more I looked at the covers produced by my stable mates, I knew I had to up my game. I was chatting with Simon via Facebook one evening about his ideas for the cover, and he kept coming back to The Sea Devils novelisation cover by Chris Achilleos. I was getting quite excited by the prospect of doing something along those lines.

I was already familiar with Rob’s work, so when he emailed us out of the blue asking if we would consider him for our Short Story Incentive scheme, I was very willing to give him a shot. And he just happened to enquire as we were about to seek out a story for Halloween.

Once I knew it was going to be set around Halloween, I knew I wanted to do a Quatermass inspired story, with definite horrific elements, sourced back to a scientific explanation/basis.

Although you can easily read it without having read Times Squared, as it features Anne, Bishop and Samson who are not in that novel. Although it references Times Squared, it does so in a way that will not spoil that novel one bit. It also has a nice callback to the first novel of this year, Moon Blink. All that said, it is very deliberately written to be read on its own, with your feet up, candles lit and the rain lashing against the window.

For (the first novel) The Forgotten Son I was interested in wrapping up the story of the Great Intelligence as seen in Moffat’s trilogy, and exploring something of its origins. So now it’s time to go back to the Intelligence as depicted in the original Haisman/Lincoln stories. Ever wondered what happened to it in those long years between The Web of Fear and The Snowmen, and how the 1995 straight-to-video film, Downtime, fits in? Well, now it’s time to start finding out.

I had the idea of the Yeti roaming through Times Square, plaguing the immense underground of New York. And by throwing in a bit of time travelling shenanigans, the title was an obvious one.

After Shaun came to me with the basic idea, it was quickly decided we wanted, ideally, an American author to write it. I turned to Rick Cross, an aspiring US author I knew via social media. We talked and he jumped at the chance. We spent a short while discussing story ideas, telling him the elements I wanted, and he came to me with a few ideas of his own. And it has turned out rather brilliantly; the first bona-fide sequel to The Web of Fear, dealing with the Intelligence from that story, as well as a story that brings back Owain, Lethbridge-Stewart’s nephew, last seen in Beast of Fang Rock. A character with a very special relationship to the Intelligence.

It’s been an exciting opportunity. Hard work, trying to remember the British rules of grammar, but I’ve enjoyed telling my story and delving into the relationship between Lethbridge-Stewart, his fiancée, Sally, and his nephew, Owain. Owain in particular has been fun, exploring his freedom of spirit, and his destiny – which is, one day, to be reincarnated into the person who will ascend to be the Intelligence.

I had this brilliant idea about the rats in the sewers of New York, and their connection to various plagues throughout the years. What if one such plague was the result of the Intelligence? Coupled with that was my desire to explore the origins of the Yeti. Who made them? How did so many of them get to be in the London Underground in The Web of Fear? Remember, in that story it is revealed that Travers only brought one of them back from Tibet with him. Hopefully Times Squared will provide fans with an interesting take on that, as well as expanding the mythology surrounding the Intelligence and Yeti.

Ever since first reading about this character in 1997 I’ve wanted to use her; indeed, she featured in an unpublished Doctor Who novel I wrote in 1998. Her connection to UNIT, and consequently the Brigadier, has been something I’ve wanted to explore since day one of this series. In particular to show the origins of how she came to know Lethbridge-Stewart and what piqued her interest in all things alien.

It was a wonderful opportunity. Andy set it all up, put me in touch with Jon, who compiled a detailed background document for the character. I had never heard of Kramer, but did my research, and it has been brilliant writing for her, exploring the young woman she was in 1969, long before she became the tough soldier in Vampire Science. I’ve been very blessed to play with all these wonderful much-loved Doctor Who characters in my book, and add one of my own creations to the mythos of Doctor Who.

As soon I was briefed on the key scene in the book, Yeti robots covered in rats coming out of the New York underground, I was onto a winner with the cover. This horrific, stark image along with the brilliant writing by Rick Cross makes this a worthy continuation to the classic Web of Fear.

We’ve had plans for a while to bring Eileen into the series, and the news of her death made us decide to make it happen sooner, to pay tribute to this great legend of World War II. It’s not often one meets a bona fide hero in one’s life, and the difference Eileen made to the security of the UK cannot be stressed enough; it was a natural thing to bring her into contact with the Doctor Who legend that is Lethbridge-Stewart.

Brigadier Lethbridge-Stewart has always been one of my favourite characters from Doctor Who, so it's a privilege to be part of bringing him back to have new adventures.

I loved writing this story because it's a great mix of monster-filled action scenes with a more thoughtful examination of how we lead our lives. It's a particular honour to be able to pay tribute to Eileen Younghusband, who lived such an amazing life.

We have included these excerpts to illustrate how important Eileen was in the defence of Britain. Apart from arguably saving Winston Churchill’s life, spending time with Dylan Thomas and acting as a guide at a Nazi concentration camp, I would encourage all fans to read these excerpts as a fascinating document of our times.

With the previous volume we collected the many short stories published in 2015, but it was a little different this time since we have released fewer short stories this year. However, as we like to spoil our readers, we decided it would be nice to produce new exclusive material for the collection, as well as give a couple of extras. And, just to make this collection even more worthwhile, and collector’s item, we’ve decided to add yet another story to the mix.

The plan was originally to release the novella alongside Times Squared, but time kind of ran away from me, so I suggested instead we release it as part of The HAVOC Files as a three-part story over three volumes. I mean, who doesn’t like a cliffhanger or two?

A unifying cover idea for a mix of stories was never going to be easy but the central idea of an incredible shrinking Lethbridge-Stewart made small work of it!
