The Sixth Doctor (Colin Baker) and his companion Peri (Nicola Bryant) continue their travels through time and space later this year, in The Sixth Doctor Adventures: Bad Terms, a box set comprising two 90-minute full-cast audio adventures. 

The first story takes the TARDIS to the Irish Sea in the eighteenth century, where pirate queen Saoirse O’Grady (Rebecca O’Mara) is in conflict with the English naval officer Sir Kenneth Rushworth (Torchwood’s Gareth David-Lloyd) – and his alien allies. 

Then, the Doctor and Peri go undercover at an elite public school, where young pupil Malcolm (Charlie Hamblett) has an unexpected connection to the Doctor. 

Doctor Who – The Sixth Doctor Adventures: Bad Terms is available to pre-order now for just £19.99 (download to own) or £24.99 (download to own + collector’s edition CD). Please note: the collector’s edition CD box set is strictly limited to 1,500 copies and will not be repressed. 

The Sixth Doctor’s latest audacious adventures are: 

Saiorse of the Seven Seas by Nina Millns 

Saoirse O’Grady, Queen of the Irish Sea, teams up with the brave Captain Peri (and her lowly second-in-command, the Doctor) to fight for justice for her people and her homeland. But her English foe, Sir Kenneth Rushworth, doesn’t just have the law on his side – he has allies not of this Earth. Allies who have a very particular interest in Saoirse… 

Red for Danger! by Nev Fountain 

New teachers Dr Pretorius (History) and Professor Brown (Biology) find a lot to alarm them at one of the most menacing places they’ve ever visited – a traditional English public school. Finding aliens among both staff and pupils, can they solve the mystery of Malcolm – a boy whose connection to the Doctor is closer than the Time Lord could ever imagine…? 

The guest cast of The Sixth Doctor Adventures: Bad Terms also includes Akshay Khanna (co-star of the Apple TV+ series, Murderbot), Ayesha Antoine (Bergerac), and Laurie Kynaston (Cradle to Grave), plus further names yet to be announced. 

Producer Jacqueline Rayner said: “We’re going back to basics – the Sixth Doctor and Peri. Their relationship is such an important one; they’ve had a vast number of adventures over the years and yet there’s always something new there to discover. 

“We have a real flavour of rollicking old-fashioned adventure stories here – first piratical perils on the high seas and then high jinks at a boarding school – but there might be a few surprises in store. Let’s just say that one of the boys at the school has a much closer connection to the Doctor than anyone would ever suspect…”
