Winter for the Adept (audio story) was former script editor Andrew Cartmel's first script for Big Finish Productions, and, as of 2014, his only one for the main monthly range. It was highly unusual for his work in the DWU because it featured the Fifth Doctor and Nyssa, rather than his usual team of the Seventh Doctor and Ace. Another "fish-out-of-water" with this story was India Fisher, who enjoyed her first Big Finish role here, several months before originating her usual character of Charlotte Pollard.
