The Twelfth Doctor Adventures begins today!

A new era for the Twelfth Doctor begins today, with Jon Culshaw taking over the role portrayed on TV by Peter Capaldi. 

The Twelfth Doctor Adventures: Run Fast, Be Kind is a six-episode audio drama miniseries, released in weekly instalments, with an epic new story arc for the Doctor set between 2015’s Doctor Who Christmas special The Husbands of River Song and 2016’s The Return of Doctor Mysterio. 

In today’s first episode, The Second Death by Alfie Shaw, the Doctor is looking for a moment of solitude as he reflects on his final night with his wife River Song on Darillium. But the universe, as ever, has other ideas. On a wasteland at the end of time, the Doctor is thrust into a fast-paced adventure with new friend Ashlorn Wilton (Gwithian Evans). 

Doctor Who – The Twelfth Doctor Adventures: The Second Death is available to download now for purchasers of the Run Fast, Be Kind six-episode series bundle, which is available for just £43.99, exclusively here. Customers will gain access to the weekly episodic downloads, as well as the box set as a single download to own (once all episodes have been released). 

This week’s episode, The Second Death, is also available to purchase individually for just £5.99 (as a digital download to own). This offer ends no later than 23:59 (UK time) on 22 July 2026. 

During the last days of history, a lone wanderer crosses the wastes of Kersarin. Everywhere he goes, he delights those he finds with stories and songs. He provides a little hope in the dark. 

His name is Ash Wilton, and there’s one thing that Ash knows for certain. You don’t get time travellers at the end of the universe. 

The guest cast of The Second Death includes Clare Bloomer as Breen/Computer, Sid Sagar as Hari/Desolate, and Robert Whitelock as Alan/Craig/Desolates. 

Jon Culshaw, the voice of the Twelfth Doctor, said: “It’s been absolutely brilliant recording with Gwithian. I love how the Twelfth Doctor and Ash are thrown together. They hit the ground running and it’s fantastic. Ash is the companion that the Twelfth Doctor would really synchronise with at this point in time, after the events with River Song. The Doctor’s always drawn to people who he can learn from and who he relates to.” 

New companion actor Gwithian Evans added: “The Twelfth Doctor is my favourite Doctor, and so to originate a companion with him has been amazing. Jon has Peter Capaldi down to a tee and there’s a real dynamic between the Doctor and Ash – it reminds me of Doc and Marty from Back to the Future. This episode’s full of mystery and intrigue, it’s a good sci-fi story with a lot of action, and the pace of it is just insane.” 

The Twelfth Doctor Adventures continues next week with The Broken Man, in which the Doctor takes Ash on his first trip in the TARDIS – to Scotland, 2016, where an archaeological mystery awaits.
