Aliens crawl all over the roof of the Radcliffe Camera as Doctor Who battles to save Earth.

It may sound crazy but it’s all in a day’s work for scriptwriter Matt Fitton.

Mr Fitton, who lives in East Oxford, finds the dreaming spires inspirational and has set many of his stories in the city’s iconic buildings.

He said: “Describing the Doctor running through the Bodleian is one of my favourite scenes, as the building makes the perfect backdrop with all the rows-upon-rows of shelves.”

The father-of-one’s break came four years ago, when a production company which makes Doctor Who audio dramas for CDs and download, invited new writers to submit stories.

Mr Fitton’s idea found the Time Lord trapped in a Jane Austen simulation and having to propose to his companion, to save her from Mr Darcy.

He didn’t win but impressed the production company, Big Finish, enough that they emailed him a few months later inviting him to redevelop his idea for an audio story.

He said: “My submission was one of 1,200 entries.

“At the time, I was entering as many writer submissions and competitions as I could but that was the one I really wanted.

“I have listened to Doctor Who audio stories since they first started in the 1990s, which was when it was not on television, during what are known by fans as the ‘wilderness years’.”

Mr Fitton, 43, who studied classics and English literature at Exeter College, has a nine-year-old son with theatre agent wife, Polly Orr.

For the past 16 years, he has worked at economic consultancy LMC Automotive, in Cornmarket Street.

He is there three days week, with the rest of his time spent writing, including many evenings and weekends.

He said: “Planning the storyline in detail takes the most time but once that is done, I can write about 4,000 words a day.

“To make the story work, people and their emotions have to be believable.”

One of his favourite parts of the process is watching the actors perform his scripts during recordings.

He has had nine stories recorded with Big Finish and has met a number of the actors who have played Doctor Who, including Colin Baker, Sylvester McCoy and their companions.

He said: “All their voices have lived in my head for years and years, so it’s slightly surreal hearing them speak my words.”
