Background: Terrance Dicks adapts Terence Dudley’s scripts for the 1982 serial. This followed Castrovalva on TV, so that’s another pair of stories to be released consecutively.

Notes: Terrance gets his first go at this TARDIS crew, so we get decent descriptions of them all – at last!: Nyssa is ‘an attractive-looking girl with brown hair and an aristocratic, somewhat haughty air’; once again, Adric is ‘a smallish, round-faced youth wearing a yellow tunic’; the Doctor’s ‘third, least willing companion [is] an ‘Australian air-hostess called Tegan Jovanka’ who is said to be ‘exceptionally forceful, even for an Australian’; and the new Doctor, who we’re told is now in his fifth incarnation, is a ‘rather slight, fair-haired young man with a pleasant, open face’ (entirely coincidentally a cricket pun there – Dicks had no idea  it was a term for how a cricketer grips the bat!). Each of the companions gets a one-line origin summary.

Observing a device that can reduce matter, Nyssa recalls that it’s a favoured method of the Master and was the way he murdered Tegan’s aunt. As the Doctor tells Monarch that only he can operate the TARDIS, it dematerialises under Tegan’s control, rather undermining his boast. Nyssa’s fainting cliffhanger that leads into the next story is omitted. 

Cover: An almost competent photo montage of Stratford Johns as Monarch with Peter Davison as the Doctor. Alister Pearson’s 1991 cover is just a noble portrait of Monarch with a suggestion of his chamber lightly etched into the background. 

Final Analysis: By this point in time, TARDIS companions exist solely to bicker and Terrance Dicks relishes the opportunity to show the previously impish Adric as an utter brat. Tegan’s brashness is accentuated too, which rather underlines how empty and bland Nyssa is. We’re even told that she manages to save the Doctor from execution because she’s ‘ standing unnoticed in the background, ignored because nobody considered her a threat’. Four to Doomsday is unlikely to be anyone’s favourite story, or indeed anyone’s favourite book; it does the job, nothing more.
