Written by P.J. Hammond, the story was commissioned as "End of Term" on 10 February 1986 as a replacement for "Pinacotheca" for episodes 9 – 12. It involved the Doctor investigating the resort of Paradise Five, while Mel goes undercover as a hostess. When this script was rejected by producer John Nathan-Turner, it was replaced in turn by Pip & Jane Baker's "Terror of the Vervoids". It was later adapted as "Paradise 5" by Andy Lane for Big Finish as part of their "The Lost Stories" series in March 2010, which scrapped all of the Trial scenes from the original script, replaced Mel with Peri, and backdated "Paradise 5" to before the events of "The Trial of a Time Lord".
