In 2000, Winter for the Adept was released by Big Finish Productions.

Cover blurb
When a teleportation experiment goes badly wrong, Nyssa finds herself stranded on the freezing slopes of the Swiss Alps in 1963. But is it mere coincidence that she finds shelter in a snowbound school haunted by a malevolent poltergeist?

When the Doctor arrives, Nyssa and the other inhabitants of the school soon discover that the ghost is merely part of a darker, deeper and more deadly game involving rogue psi-talents and something else... Something not of this Earth.

This story takes place between Time-Flight and Arc of Infinity.
