Strange alien artifacts begin appearing inside UNIT’s Black Archive. Each object is unmistakably linked to a different regeneration of the Doctor, but they’ve been tampered with. A corrupted energy signature of unknown origin pulses through them, and their sudden arrival has torn tiny ruptures across time and space.
To solve the mystery, UNIT calls upon a little-known incarnation of the Time Lord: the Fugitive Doctor. But how does UNIT know about her? And is she The Doctor they expect?
The Doctor, Osgood and Andrew are joined by Kate Lethbridge Stewart. A final mysterious object is manifesting, this one at the pinnacle of UNIT Tower itself.
A Time Bomb! Which threatens a dark future for all of the Doctor’s incarnations.
Only this Doctor can save herself – and her other selves – from this intricately woven scheme.
Doctor Who – Circuit Breaker: Full Circuit out today!
Over the course of the mixed-media Doctor Who adventure Cicuit Breaker – which has encompassed comic books, novels, games, and more – the Fugitive Doctor has been working with UNIT’s Petronella Osgood to resolve a crisis across time and space.
That crisis reaches its climax today in Circuit Breaker: Full Circuit. This full-cast audio drama stars Jo Martin as the Fugitive Doctor and Ingrid Oliver as Osgood, as well as Omari Douglas (It’s A Sin) as Osgood’s assistant Andrew Turner, and Jemma Redgrave as UNIT Commander-in-Chief Kate Stewart (in her first chronological appearance since TV spin-off The War Between the Land and the Sea).
The Doctor and her allies have uncovered the villain behind the unusual anomalies – the Conductor (Dan Starkey). This uniquely scheming Sontaran is making his final moves, which involve a Time Bomb that threatens all of the Doctor’s future selves…
Doctor Who: Circuit Breaker: Full Circuit is now available to purchase for just £13.99 (download to own) or £21.99 (download to own + collector’s edition CD), exclusively from the Big Finish website. Please note: the collector’s edition CD box set is strictly limited to 1,500 copies and will not be re-pressed.

Director Barnaby Edwards said: “It was a great joy to work with the Fugitive Doctor. This was my first experience with Jo, and I’m keeping everything crossed that it won’t be my last. I love her! She’s so fresh and funny and natural. Robert wrote a really good script and Jo completely locked into the humour and the pathos of it. She defines the sound and rhythm of Circuit Breaker.”
Esmie Jikiemi-Pierson, Circuit Breaker editorial lead, added: “It’s exciting to have the Fugitive Doctor at the heart of this story. She’s a fantastic character, and Jo as an actress is a gift that keeps on giving. She is capable of so much depth and tenderness, but also such strength, and that lends itself so well to the character.
“People think they know the Fugitive Doctor from everything we’ve seen of her, and part of the process of writing this was asking: how much of what we’ve seen is a front that she puts up to protect herself from the world, and how much of it is really who she is in her heart? Which was a really fun dichotomy to play around with.”
