The Uncertainty Principle

Doctor Who: The Uncertainty Principle stars Wendy Padbury as Zoe HeriotAvailable now from Big Finish’s masterful Companion Chronicles range comes The Uncertainty Principle, a weaving, duel layered tale of memories and harsh reality that perfectly captures the tone and pace of the Second Doctor’s adventures.

Held prisoner by the mysterious Company, Zoe Heriot, protected by the Time Lords must fight to keep her memories of her time with the Doctor from falling into the wrong hands…and so Zoe recalls a journey to Earth in the past, to a funeral of a young woman called Meg, who was involved in scientific experiments that are bringing forth sinister alien creatures.

Only the Doctor, Jamie and Zoe can stop them.

Written by Simon Guerrier and directed by Lisa Bowerman, Big Finish’s The Uncertainty Principle stars Wendy Padbury and Charlie Hayes and is available now on CD for £8.99 and £7.99 on download.


Everyone has a favourite Doctor and mine - just for his honesty, his fairness and his ability to not notice the Master's awful, awful disguises/anagrams (Sir Gilles Estram!?!) - has to be the Fifth Doctor, Peter Davison. The stories didn’t serve him as well as his acting served those stories.
