Their adventures across time and space are far from over – the iconic pairing of the Fourth Doctor and Leela, who starred together in Doctor Who TV adventures from 1977 to 1978 – will return in three brand-new box sets of full-cast audio drama to be released throughout 2025. 

The first of these is entitled The Hellwood Inheritance and features two exciting new stories. The titular story finds the time-travelling duo investigating a safari park where the entertainment is undead. Then, in The Memory Thieves, the TARDIS lands on a planet where the inhabitants suffer constant memory loss and are stalked by mysterious monsters. 

Doctor Who – The Fourth Doctor Adventures: The Hellwood Inheritance is now available to pre-order as a collector’s edition 3-disc CD box set (+ download for just £24.99) or as a digital download only (for just £19.99), exclusively here.

Complete story information for these two fantastic Fourth Doctor and Leela stories: 

The Hellwood Inheritance by Alan Barnes

When the Doctor and Leela are chased through the countryside by a headless knight, it’s only the start of their problems. Because they are in the grounds of Hellwood Manor – the first safari park for ghosts! 

Mistaken for parapsychical investigators, the TARDIS team are shown the mysterious ‘ghost catcher’ device that’s made the whole scheme possible. 

But it can’t really be catching ghosts, can it? What’s really happening in Hellwood? 

The Memory Thieves by Phil Mulryne

The colony world of New Pasithea was peaceful for many years. But strange electric pulses started to be detected in its forests... and then they started to get stronger... and then people lost their memories... 

The Doctor and Leela land in a community in turmoil, doomed to insanity by the mysterious ‘Abeyance’ unless the TARDIS crew can save them. 

But with reports of monsters being seen in the locality, this may prove harder than expected. Can they rescue the minds of the colonists? Or will they forget what they have to do... 

The Hellwood Inheritance guest stars Tamzin Outhwaite – known for EastEnders and New Tricks as well as the Doctor Who episode Nightmare in Silver – as Joan Stone, a parapsychologist’s assistant. 

The box set’s guest cast also includes Rosalie Craig (The Serpent Queen), Rosie Day (Outlander), Richard James  (Space Precinct), and Luyanda Unati Lewis-Nyawo (Wednesday).

Producer David Richardson said: “As I write this, I’m blissfully enjoying the Blu-ray release of Doctor Who – The Collection: Season 15 and happily reflecting how lucky we are to be working with Tom Baker and Louise Jameson again at Big Finish, on brand new stories in time and space. 

“The Fourth Doctor and Leela are a perfect pairing – the bohemian Time Lord and the fearless warrior – and it was a blast to take them to new places in this new box set of The Fourth Doctor Adventures.” 

All three of 2025’s Fourth Doctor Adventures box sets (due for release in March, June and September) can be pre-ordered together in a bundle for just £70.50 (collector’s edition CD + download) or £57 (digital download only).
