That most bombastic and colourful of Time Lords first arrived on our screens on 16 March 1984 at the end of the Doctor Who story, The Caves of Androzani. To commemorate the occasion, March 2024 sees the Sixth Doctor materialise in The Quin Dilemma, a six-part audio drama starring Colin Baker.  

“Ol’ Sixie” is reunited with not only his television companions Peri (Nicola Bryant) and Mel (Bonnie Langford) but also two companions originally created for audio in the shape of Constance Clarke (Miranda Raison) and Flip Jackson (Lisa Greenwood). 

The guest cast also contains a brilliant selection of actors making their Big Finish debuts, including Jonnie Broadbent (Thomas and Friends) as the villainous Quins, Carrie Quinlan (John Finnemore's Souvenir Programme), Andrew Dunn (Dinnerladies), Sanjeev Kohli (Still Game) and Nikki Kelly (Hi-De-Hi).  

Doctor Who – The Sixth Doctor Adventures: The Quin Dilemma is available to pre-order now for just £22.99 (collector’s edition CD box set + download) or £18.99 (download only) exclusively here. The collector’s edition CD box set is strictly limited to 1500 copies and will not be repressed.   

The six stories in the box set are: 

The Exaltation by Jacqueline Rayner

Hints of a temporal anomaly bring the Doctor and Mel to Arunopal on the day King Otho steps down as ruler. But Otho has a dilemma – which of his five sons should succeed to the throne? He has a deadly game in mind to solve the problem – and the target is a certain Time Lord…  

Escape From Holy Island by Chris Chapman 

The history books tell us that on the 8th June, 793 AD, the Holy Island of Lindisfarne was burnt to the ground by Viking raiders. But history also records that “fiery dragons were seen flying in the sky” - can that be true? With time running out, the Doctor, Peri and a young H.G. Wells try to mobilise the island’s monks as the real raiders of Lindisfarne thunder over the North Sea - and they don’t look like Vikings…  

Sibling Rivalry by Robert Valentine 

The Doctor, Constance and Flip are stuck on an alien planet in the middle of a civil war. To make matters worse, the Sontarans have invaded. To make matters even worse, two of the dastardly quins – the volatile Clarent and the odious Dellan - are both on the scene... and the Doctor may not survive their furious competition.  

Children of the Revolution by Robert Valentine 

With their plans causing havoc, wicked quins Clarent and Dellan are at loggerheads. But as the schemes of Sontaran Battle Marshal Skurr reach their climax, the only thing more dangerous than the brothers’ competing against each other… is the brothers joining forces.  

The Thousand Year Thaw by Chris Chapman  

Once every thousand years, the frozen planet of Zycros thaws, revealing the most fertile soil in the universe. For a brief window, Zycros becomes the farming capital of the cosmos, and that brings with it many visitors - including a small blue box and its two occupants, keen to stretch their legs. But as the ice melts and the temperature rises, the Doctor and Peri realise that this pleasant stroll may be the last one they ever take together...  

The Firstborn by Jacqueline Rayner 

The Quins have succeeded in their quest – a little too well. Multiple Doctors congregate on Arunopal, bringing with them a terrible threat to reality… 

Producer Jacqueline Rayner says: “I think I asked if I could do a 40th anniversary story almost as soon as I took on the producer's job – it was a milestone that just had to be celebrated. How incredible is it that Sixie's still going strong four decades after his debut?  

“Our job with this story was to show just why dear ol' Sixie is so beloved by Big Finish fans, and why he's endured for so long – of course, the main answer to that is 'Colin Baker', but for us to shine a light on what he brings to Doctor Who.  

“The title is clearly an homage to The Twin Dilemma, but we're going 2.5 times better... and in terms of Doctors, four times better. Yup, we end up with no fewer than four Sixth Doctors.

“This set was such fun to do, and what a joy to have Colin, Bonnie, Nicola, Miranda and Lisa together – with our brilliant guest stars too. I'm told we set the record for most actors in studio for a Big Finish recording ever!”  

This box set also includes the first of 2024’s bonus Interludes, The Memory Eaters, by Alison Lawson. Interludes are hour-long audiobook adventures with special music and effects, bundled exclusively as download extras with selected classic Doctor box sets. 

A second Sixth Doctor Adventures (Title TBC) box set will follow later in the year. Both can be pre-ordered together in a bundle for just £44 (collector’s edition CD box set + download) or £36 (download only).  

All the above prices include the special pre-order discount and are subject to change after general release.
