Peter Davison, Janet Fielding and Sarah Sutton reprise their roles as The Doctor, Tegan and Nyssa, in a run of stories following on from 1983's adventure The Arc of Infinity: Today should be much like every other day for Hargreaves, the computer consciousness that co-ordinates daily life aboard the spaceship...
Aquitaine, stationed on the outer fringes of a black hole. Water the plants, run the diagnostics, cook the Captain's breakfast; then tidy the plates away, rotate the ship, clean the windows of the observation deck.
When at last the day's work is done, Hargreaves will dim the lights in the sleeping quarters. But no-one will sleep aboard the Aquitaine tonight. Because the Aquitaine's crew is missing.
But today will be different. Today, a space/time ship called the TARDIS will materialise in the botanical section, bringing the Doctor, Nyssa and Tegan aboard the Aquitaine.
Together, they'll seek to discover the truth of what happened to Hargreaves' crew...if only the ghosts will let them. Forever kept busy, Peter Davison's most recently been seen on the London stage in the critically acclaimed The Vertical Hour, and in the musical Gypsy opposite Imelda Staunton.
The Doctor, Nyssa and Tegan team first met in 1981's Doctor Who adventure Logopolis, where Tegan and Nyssa were on hand to help the Doctor (Tom Baker) regenerate into his fifth incarnation (Peter Davison).
One of Big Finish's last outings with The Fifth Doctor, Tegan and Nyssa was in Doctor Who - The Fifth Doctor Boxed Set, one story from which (Iterations of I) won the Scribe Award at the 2015 San Diego Comic Con.
