David Fisher

Doctor Who script editor Anthony Read commissioned Fisher to write The Stones of Blood (1978) and The Androids of Tara (1978) for The Key to Time storyline of season 16, and he was subsequently commissioned to write The Creature from the Pit (1979) for the seventeenth season during the tenure of Douglas Adams as script editor. He worked on a story called "A Gamble with Time", also for the seventeenth season, but owing to the divorce proceedings ending his first marriage, he was unable to finish the scripts. That story was reworked and completed by Douglas Adams and then-producer Graham Williams and was recorded and broadcast as City of Death (1979) under the pseudonym of David Agnew. His final Doctor Who story was season eighteen's The Leisure Hive (1980).

Fisher novelised both The Leisure Hive and Creature from the Pit for the Target book range of Doctor Who novelisations, and appeared extensively on the interview features accompanying the DVD release of the former story. Fisher also wrote novelisations of The Stones of Blood and The Androids of Tara for audiobook releases in 2011 and 2012, which received print editions in 2022. He was also interviewed for a documentary accompanying the DVD release of City of Death.

Fisher's other work included writing for the television series Dixon of Dock Green, Crown Court, and Hammer House of Horror.
