In 1975, he was commissioned by then-Doctor Who script editor Robert Holmes to pen a two-part serial entitled The Angurth for the programme's thirteenth season.
Pringle delivered two proposals for four-part stories to the production office in August, one called The Darkness (possibly featuring the Daleks) and another entitled War Game.
Saward and producer John Nathan-Turner had also come to the realisation that the story did not merit four episodes, and so Pringle was asked to condense it down to fit the two-part slot for Season Twenty-One.
[citation needed] Much of Pringle's more recent work has been for the radio including adaptations of The Wolves of Willoughby Chase and J.
His 2001 BBC Radio 4 play Hymus Paradisi about the life of composer Herbert Howells won a Sony Award.
