A Dereham writer who penned a series of four-part stories for Tom Baker's Doctor Who says interest in the classic series is increasing thanks to the show's revivial.

His imagination created the Creature in the Pit, the Androids of Tara and the Argolin.

More than 30 years ago, David Fisher was responsible for the enthralling and sometimes downright frightening escapades of Tom Baker's Doctor Who and his very stripey scarf.

And now, as he brings the Ogri back to life with a new audio book of The Stones of Blood, the Dereham-based script writer has found interest in the classic tales is growing once again.

Mr Fisher was first asked to have a go at penning a Doctor Who adventure by the then script editor Tony Read.

A fan of the series himself, the request went down particularly well with his son and two daughters.

'My children thought it was marvellous,' he said. 'The way we all watched Doctor Who was from behind the sofa.'

The 82-year-old wrote his first adventure – The Stones of Blood – for the 16th series of the drama featuring Tom Baker and went on to write two more four-part stories, The Androids of Tara and The Creature From the Pit.

He also co-wrote a fourth with Douglas Adams called City of Death, which aired as part of the 17th series.

Mr Fisher said he enjoyed his time with the show which gave his imagination free rein – to a certain extent.

'I remember being called in once,' he said. 'The producer said, 'We've got a major problem. We've had letters from 12-year-old boys saying the physics couldn't work. In the future, can you guarantee the physics will work'?'

Mr Fisher decided to get in touch with scientists working at a Cambridge astronomy centre, near where he lived, and asked if he could talk some ideas through with them.

'It turned out they were Doctor Who mad,' he said.

The experts helped him not only come up with a way for the Creature in the Pit to threaten an entire planet with a neutron star but also a way to stop it. Mr Fisher said: 'They said 'that's perfectly simple too. Just wrap it in tin foil'.'

The writer's episodes aired between 1978 and 1980, with Mr Fisher joining actors and crew on set for the rehearsals and filming of each one.

But he then decided to move on and try his hand at other television series, as well as writing books and even a musical.

Mr Fisher, who moved to Dereham in 2001 with his second wife Barbara Weller, said: 'Doctor Who became much more serious. They lost the comedy element which I thought was a pity. When it was light I was happy to write but it became a bit heavy – the last thing you want to do is bore yourself when you're writing.'

Despite no longer writing for the television shows, the grandfather-of-seven has certainly not left the series behind. As well as adapting his own stories into novels, the writer has recently had the task of turning his first-ever Doctor Who tale into an audio book.

He said interest in the older stories seemed to be increasing thanks to the revival of the series, which currently features former UEA student Matt Smith as the 11th Doctor.

'Doctor Who seems to be having another lease of life. I've just had to do an interview for someone who's writing for an American Doctor Who magazine.

'It seems to have taken off again.'

Mr Fisher's other writing credits include Dixon of Dock Green, Hammer House of Horror and Crown Court for Granada Television.

But his CV could have included one or two other high profile programmes.

'I foolishly once turned down Coronation Street because it meant going up to Manchester a lot,' he said. 'I was also approached very early on by Not the Nine O'Clock news. I said no, I was trying to write a sit com. Who knows what would have happened if I had said yes?'

The Doctor Who: The Stones of Blood audio book is available now as both a digital download and four-CD set.
