rise to a mental disorder termed Robo-phobia. This is shown as a paranoid delusion that robots are actually the living dead, intent on harming humans. The Robots of Death also shows that it is possible to reprogram robots so that they can break the restrictions on harming humans, as robotics genius Taren Capel has discovered in his attempts to free his robot "brothers" from their 'slavery'. Kaldor City is also the setting of the Past Doctor Adventure Corpse Marker, where we get to see the city and its ruling board of "Topmasters". At the time of Corpse Marker, the Board comprises twenty Topmasters from the founding families, and they are seen to be keen to keep anyone not from a founding family off the board. The novel also introduces the character of Carnell to Kaldor City, who is a psychostrategist on the run from a corrupt "Federation" and hiding out in the city whilst ingratiating himself with the board by helping them compose their strategies: Carnell is a character from one of Chris Boucher's Blake's 7 episodes, "Weapon", broadcast in 1979, and this novel is the first time that the fan-theory that Doctor Who and Blake's 7 take place in the same fictional universe has received any kind of semi-official recognition. This theory had its roots in a report that Blake's 7 creator Terry Nation wanted to introduce his Doctor Who monsters, the Daleks, into Blake's 7 but was prevented by the BBC. The novel also introduces the concept of the sewer-pits, the slums of Kaldor City where the underclass try to scrape their living. The slums are the breeding ground of a new breed of terrorist, the Tarenists, who have adapted the teachings of the late Taren Capel into an almost religious doctrine, preaching the downfall of the ruling class at the hands of the robots. By the end of the novel, Topmaster Uvanov (formerly commander of the storm mine in The Robots of Death, and not a member of a founding family) has secured his succession to Chairholder of the Company Board. Some of the plays in the series also feature the Fendahl: a race of creatures also created by Boucher in 1977, in the Doctor Who television serial Image of the Fendahl. Audio plays In 1999, Magic Bullet Productions approached Chris Boucher to discuss the possibility of creating a range of audio plays based on the characters
