In a sprawling six-part full-cast audio adventure, the Doctor and his spirited companions Tegan (Janet Fielding) and Turlough (Mark Strickson) face a time-shifting crisis and a horrifying Auton invasion!  

Jon Culshaw joins the 1980s TARDIS team as Brigadier Lethbridge-Stewart and the shape-shifting robot Kamelion. The world-class impressionist and actor also recaptures the silky tones of Anthony Ainley as the time-travellers face the Master once more... 

Doctor Who – The Fifth Doctor Adventures: Forty 2 is now available to own as a collector’s edition CD box set (+ download for just £19.99) or digital download (for just £16.99), exclusively here. 

Survivors star Lucy Fleming makes a special guest appearance as Veronica Holmes from the Ministry. BAFTA award-winning actress Juliet Aubrey (Professor T, The Infiltrator) also joins the out-of-this-world cast as the unusual Auton, Prodigal.  

The Auton Infinity by Tim Foley

Snowdonia. UNIT is running a training exercise with the Brigadier in attendance. Except it isn’t long before things start to go badly wrong. The fake aliens primed to attack the troops might not be so fake after all, and a temporal disturbance attracts the Doctor, Tegan and Turlough into the fray.  

Old enemies are on the scene with a deadly plan - but they might be the least of the Doctor’s worries.  

Because he’s recently been sent backwards and forwards through his own lifetime… and he’s finally going to find out why. 

Peter Davison said: “I was very much in the beginning of my career when I did Doctor Who. I’d watched the series from when it started and it was very exciting to suddenly be there as the Doctor. We had a nice time making it. It was a little family and I was very fond of [the cast]— we’ve all stayed in touch. 

“I was determined to be a breath of pleasant fresh air. I felt that being the first younger Doctor and slightly more heroic in the traditional sense legitimised me and improved the legacy. I like to think that Big Finish is very much a part of my legacy.” 

Janet Fielding added: “A gift of Doctor Who has been the friendships. It’s enormously important and a wonderful bonus. It really does feel like a family — it's lovely.” 

Mark Strickson said: “Looking back it’s been an incredible 40 years and a totally unexpected gift that’s kept our friendships alive over a lifetime. Of course, we’ve also worked on new Doctor Who stories featuring our old characters with great scripts, good company and lots of fun. All I can hope is that we’ve given the fans as much fun as we’ve had.”
