Fisher is a British writer best known for his Doctor Who serials. His first story, The Creature from the Pit, was broadcast in the 1978 season of the television show and later became a popular novelisation. He later contributed two other stories, The Stones of Blood and The Androids of Tara for the programme’s sixteenth and seventeenth seasons respectively.

His final serial, 1980’s The Leisure Hive, was the first to be produced under John Nathan-Turner’s stewardship. It also marked the return of a series that had been on the brink of cancellation, and heralded a dramatic change in the programme’s direction for the new decade.

He wrote a number of other scripts for television including Dixon of Dock Green, Hammer House of Horror and The Adventures of the Weird Sisters. He also penned many novels and short story collections, and was a regular contributor to the Spectator magazine.

During his time at the BBC, he was commissioned to write four stories for Doctor Who. He was only able to complete his final two, City of Death and The Leisure Hive, for the series, which he was credited with writing under the pseudonym David Agnew.

Although he had never written a thriller before, the opportunity to write for Doctor Who sparked an interest in him and allowed him to experiment with different genres. This resulted in a couple of great tales, the aforementioned Creature from the Pit and The Leisure Hive.

The former was a fast-paced thriller, and Fisher did a good job of building up the tension, while making the story exciting and well-paced. While some of the dialogue was a little over-the-top, the action scenes were well done and the characters developed nicely.

While Fisher is most well known for his work with the BBC, he has also written a variety of other fiction and non-fiction books, including a biography of the Hungarian Jewish child survivor Joseph Kotz. He has also collaborated with a number of people in the media, most notably with Terry Bradshaw and Harry Markopolos.

He is a former journalist, having started his career at Life magazine in the 1970s. He subsequently worked for several other publications, including The Daily News, where he was a weekly sports reporter and an editorial writer. He has also been a columnist for the New York Post and The Wall Street Journal. He has also been a regular radio host on WNEW radio.

His most recent book is a collaboration with conservative firebrand Glenn Beck, entitled Addicted to Outrage. It will be published in September 2018.

He has also written a number of non-fiction books, most notably the political memoir The Fire Breathing Liberal with former Member of Congress Robert Wexler. It was a bestseller and appeared at number six on the New York Times list. He also co-authored a book with Hall of Fame quarterback and broadcaster Terry Bradshaw, It’s Only A Game. It was a bestseller and was reprinted three times.
