To promote their their Circuit Breaker multi-platform Fugitive Doctor adventure, the official Doctor Who social media accounts have released a new photo of Ingrid Oliver in her role as UNIT scientific advisor and Black Archive custodian Petronella Osgood.

Gone from her latest look is the white lab coat and elements of the Doctor’s wardrobe — Osgood has come into her own as a UNIT operative and dresses less like a Doctor fangirl.

The story event will see a single, escalating crisis play out across multiple formats from June to September, with each chapter unlocking new clues, new dangers… and a new side to the Doctor. Circuit Breaker kicks off on 25 June with Calling the Doctor, a message from Osgood written by Doctor Who novelist Esmie Jikiemi-Pearson, who is the editorial lead crafting the overall narrative of the adventure.

The synopsis of Circuit Breaker:

In the depths of UNIT’s most secure facility, the Black Archive, familiar objects have been pulled through time and space surrounded with a dangerous energy signature threatening to tear reality apart. With time running out, newly appointed Head of the Black Archive, Osgood (Ingrid Oliver) and her assistant Andrew (Omari Douglas) turn to the only person who can help… the Doctor (Jo Martin).

This is no ordinary crisis, and not the Time Lord they are familiar with. As the Doctor confronts her most infamous enemies such as the Daleks, Cybermen, Sontarans and a rogue Weeping Angel, she is forced to complete a mission with an insidious presence lurking in the shadows.

Secrets begin to surface, and trust between UNIT and the Doctor begins to erode as those who idolise her start to question if she really is the Time Lord they thought they knew…

This adventure marks the third Doctor Who multi-platform event following the stories Time Lord Victorious and Doom’s Day.

On 8 July, Osgood will share an adventure with the Fugitive Doctor in Adversary of the Daleks from Titan Comics, a story written by Dulce M. Montoya and Dan Watters, with art from Roberta Ingranata and Sami Kivelä.

Doctor Who: Circuit Breaker begins on 25 June with Calling the Doctor by Esmie Jikiemi-Pearson on the UNIT website. You must have a BBC account to access the UNIT website.
