The fifth story in the abandoned season was to be "In The Hollows of Time" which in the audio version has lost its initial preposition. This release remains unopened, having also arrived with the several others at Christmas 2017.
The original sixth story is again completely unavailable, with only the title being known - "The Children of January". It was apparently written at time and was supposed to have been made into one of this series of audio adventures, but it has not yet happened and the script has never surfaced. Instead I decided to finish the original season 23 with a repeat showing of the 1985 short-episode audio story "Slipback". I have had these CDs since April 2005 and listened to it once at the time.
Of course, in September 2026 I will resume with the broadcast season twenty-three. Perhaps in early 2027 I will let you know which I preferred!
