Pseudoscope have released teasers for every story in Time Shadows. Mine is by far the briefest. I prefer to think of it as succinct.
My story is called Mixed Signals and features the Fifth Doctor and Nyssa, as played by Peter Davison and Sarah Sutton. It is set between the TV stories Time-Flight and Arc Of Infinity.
So without further prevarication here is the teaser for Mixed Signals:
"Sanity is in short supply on the planet Bantrak. Can the Doctor and Nyssa survive a visit without losing theirs?"
