When the Doctor’s not around, the Master cuts loose. Sacha Dhawan’s incarnation of the wicked Time Lord returns for three brand-new adventures in his latest box set of audio drama. 

This time around, the Master causes trouble on an interplanetary cruise ship, teams up with a disgraced Sontaran, and has to confront a particularly troublesome adversary – his own conscience. 

In the second of the three episodes, Dhawan is joined by guest stars Dan Starkey (known for playing many Sontarans throughout Doctor Who and its spin-offs) as Vegg and Jacqueline King (recently seen as Sylvia Noble in Doctor Who’s sixtieth anniversary specials) as the villainous humanoid wolf Sir Florencia Fang. 

And, in the third episode, Daisy Head (Dungeons & Dragons: Honor Among Thieves, Shadow and Bone) makes her Big Finish debut as Renata, the Master’s fellow prisoner in a reformation facility. 

The Worlds of Doctor Who – Call Me Master: Monsters is now available to pre-order from just £18.99 (download to own) or £22.99 (download to own + collector’s edition 3-disc CD box set), exclusively here. Please note: the collector’s edition CD box set is strictly limited to 1,000 copies and will not be repressed. 

The Craft of Corruption by Alison Winter 

The Master is posing as ship’s counsellor on an interstellar cruise liner: the fastest transport in a galaxy where lightspeed travel is outlawed by the overbearing Interstellar Protection Corps. 

All he needs to do is keep out of trouble until the ship crosses into a sector outside IPC jurisdiction. But trouble abhors a vacuum. 

The Ideal Quarry by Jody Houser 

To make his journey more interesting, the Master has decided to take on a travelling companion – disgraced Sontaran Vegg, who is keen to get home for his execution. 

But soon the Master and his escort are marooned on a world where they are not the only hunters. In fact, they are the quarry... 

Reformation by Lisa McMullin 

The Master is incarcerated in a reformation chamber where only his own moral conscience can free him. 

He’s in big trouble. 

Producer Heather Challands said: “After the whirlwind of the first box set, I wanted to keep throwing the Master into things. He’s on far more solid ground and he’s ready to have fun. We have a sci-fi caper on a spaceship with the Master as a matchmaker, an unlikely friendship with a disgraced Sontaran that’ll make you wonder who is the hunter and who is the hunted, and the Master facing his demons. Monsters are synonymous with Doctor Who. But what makes a monster? Who is the most monstrous? Is there a monster inside of everyone? Maybe the Master is the worst monster of them all. 

“Our company is led by Sacha’s incredible performance but it’s great to have actors like Dan Starkey, Jacqueline King and Daisy Head joining the ranks. Seeing Dan bringing a Sontaran to life was such a highlight for me – he does it so wonderfully, humorously and fearlessly. Vegg and the Master made quite the duo! All of the actors involved were so fun to have in the studio and it made for a mad and marvellous time.” 

This box set marks the Big Finish debut of Jody Houser, known to Doctor Who fans as the writer of many Titan Comics stories. Jody said: “In the comic stories, I’ve written for seven different Doctors and several different Masters, most prominently Missy, but this is my first time writing Sacha’s Master, so that was very exciting! 

“This version of the Master is a really interesting evolution from Missy, who was much more whimsical and felt much more in control. This is the Master who’s known what it’s like to be in control and has decided he’s just not into that right now.”
