Winter for the Adept (audio story)

 was the tenth audio story and one of Big Finish's Doctor Who monthly range of stories.

Publisher's summary
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.
