Master of disguise, disarray and disorder. The Master has always enjoyed creating chaos, but this incarnation revels in it more than most. A new Master is unleashed upon the universe, and he is taking his time – and pleasure – in finding out exactly who he is… 

The Doctor’s arch-nemesis – in his most recent incarnation, as seen on TV from 2020 to 2022 – is back to enact cunning new schemes and, this time, there’s no Doctor around to stop him! 

The Worlds of Doctor Who – Call Me Master: Inner Demons is the first of two forthcoming box sets starring Sacha Dhawan as the mischievous Master and is now available to pre-order as a collector’s edition 3-disc CD box set (+ download for just £22.99) or as a digital download only (for just £18.99), exclusively here. 

Story details and writers of these three masterful tales are as follows: 

Self-Help by Robert Valentine 

The Master is having a crisis of the existential variety. 

While he may have a classic diabolical scheme on the go, the dastardly Time Lord’s latest incarnation isn’t quite feeling himself. In fact, he’s not even sure who he is anymore. He needs help. But can he help himself? 

Valentine said: “Where Sacha's Master fits into the timeline is a deliberate mystery, so I thought it would be fun, in the context of starting a fresh series with him as our antihero, to embrace his identity crisis in a big way and make that the point of the story – he doesn't know where he fits in, and that's a huge source of anxiety for him.” 

The Clockwork Swan by Georgia Cook 

Opening night is approaching for the latest presentation at cultural theme park Historica Dramatica: Earth-set whodunnit The Clockwork Swan. But cast and crew are being murdered...  

Enter a mysterious stranger. Who better to solve the crime than galaxy-renowned detective LeMaitre? Only, LeMaitre isn’t all he seems... 

Cook said: “The Master has such a wonderful history of putting on personas and adopting monikers and different costumes. People tend not to notice that he’s not always doing them particularly well! It's so great to add to that mythos, with him hamming it up trying to portray a Poirot or Sherlock Holmes-style detective.” 

The Good Life by Una McCormack 

On a distant Island, a group of holy men and women work together to keep the Balance. Elta, one of the Shore-folk, has come to learn. But there’s a new man on the Island – the first in living memory – and it’s not clear whether he’s saint or sinner. 

Is it only coincidence that the weather seems more changeable these days? That people are angrier and turning to violence? Where, wonders Elta, is this all heading – and does the stranger even know himself? 

McCormack said: “My initial pitch was that we do something similar to Mervyn Peake's novel Mr Pye. The hero of that novel arrives on the island of Sark, where he carries out so many good deeds that he begins to sprout angel wings. I really liked the idea of the Master trying to be good but not being very good at it.” 

The box set’s guest cast includes Richard Fleeshman (Coronation Street, The Sandman), Dave Hearn (The Play That Goes Wrong, The Goes Wrong Show), and Bethany Antonia (House of the Dragon, Nolly).
