My dad’s dementia started with problems with short-term memory, He became obsessed for instance with the length of the grass at my house. He used to come and tell me that we needed to cut the hedges. He would say that again and again in a loop, and I used to snap at him because at the time I did not understand dementia.

The most traumatic experience is when people with dementia realise they are ill. I saw my father pass through that and fight it with all his will. He was on his knees, repeating: ‘What’s happening to me, what’s happening to me? I am Ronnie Eccleston.’ It was devastating.

Like many, many people across Britain today, Chris bears the pain and loss of a dear parent who was taken by this incredibly vile condition. He wanted to not only record his father’s journey, but to celebrate his life, and that of his family also. We are privileged he has decided to take this journey with Simon & Schuster UK

I was quite stunned to be asked if I would write a book as part of the upcoming 50th Anniversary series. It was both an exciting and fairly intimidating prospect, having never written a novel before, but I knew it was an opportunity I didn’t want to pass up. The scenario that Andy gave me was too interesting to refuse.

Alyson’s short story needed very little work, and since then I’ve called upon her military knowledge for other books, so it was an easy call to invite her to join the line-up for The Laughing Gnome. For someone who’s done little professional prose writing, she turns in a very solid piece of work, which is every editor’s dream. As we are celebrating fifty years of the Brigadier, it was forgone conclusion that we would go back to the beginning, his first appearance in Doctor Who – The Web of Fear, as written by Mervyn Haisman and Henry Lincoln. Like all the authors for this range, I gave Alyson the basic premise; put Dame Anne into the missing two weeks mentioned in The Web of Fear – during a small briefing scene between Colonel Lethbridge-Stewart, Captain Knight and the Doctor – and finally show just what did happen when the mist started spreading across London, and add to that the idea that Dame Anne will be faced with the notion that she could, theoretically, changed things to ensure her father is never possessed by the Great Intelligence! Alyson jumped at the chance, and soon had an outline ready to go.

The London Event, indeed The Web of Fear, was the making of Lethbridge-Stewart, but was never just his story. There’s an awful lot that goes on off camera there; the slow advance of the mist and Web, the escalation of the crisis, and the total evacuation of London – no mean feat! Introducing an older, experienced Anne who has known both joy and loss over the years into that scenario presented some interesting questions. After everything she’s been through with HAVOC, you would think Anne would know better than to try and change the past; but when faced with the chance to save a loved one from a truly horrible fate, who’s to say to what lengths she might go? It also presented a chance to explore a little further the relationship between the Travers family and the Silversteins. I always felt bad for Mr Silverstein, getting bumped off simply for being unlucky enough to own the Yeti, and revisiting this point in time allowed me to touch on the repercussions that his death would have on those closest to him.

The Web of Fear is rightly regarded one of the gems of Doctor Who in the ’60s. It’s brilliantly written and well directed and has aged very well. When Candy Jar asked me to illustrate a cover depicting another story set during the same period I was really thrilled, especially when they asked me to show London deserted and covered in web (which was not seen in the original story but mentioned). It took a number of roughs to do justice to the idea, but when I saw some images of London in smog I knew the direction to take.

The debut of the first female doctor and her team of friends is a momentous occasion in the Doctor Who universe. We are delighted to give audiences the chance to experience this exciting moment on the big screen

We are thrilled to collaborate once again with BBC Studios to present this very special cinema event for Australian fans – particularly in ushering in the enormously talented Jodie Whittaker as the Thirteenth Doctor.
