Written by Michael Feeney Callan, this story was commissioned on 5 February 1985. After the news of the hiatus, Callan was asked by the production team to continue with the story but as four 25-minute episodes but was backed up to the original 2 part-45-minute episodes. Nathan-Turner hoped to have Bob Gabriel direct the adventure, who directed some of the earliest episodes of EastEnders in 1985. It had been planned that an adaptation of this story would appear as part of Big Finish's "The Lost Stories" range, but fell through due to the author's other commitments and was replaced by "The Macros".
