The letters page has a letter from Matthew May titled "ADRIC?" It says, "Could you do a season of the Fourth Doctor adventures where he is traveling with Adric? It would take place between TE KEEPER OF TRAKEN and LOGOPOLIS. I would like to think they had some interesting adventures, just the two of them. You could do one with the Daleks and/or the Sontarans because Adric never encountered either of them during his travels with the Fourth of Fifth Doctor."
Nick Briggs' answer is most startling, "It's certainly something we'd consider doing." !
of course, I would not hold my breath. Nick has also stated that THE BOY TIME FORGOT was not his favorite cd story that was put out.
