Roots: There are references to Vespas, the Rolling Stones, the Beatles, the Pied Piper, Che Guevara, Fidel Castro, Karl Marx, Wittgenstein, Disney, Mata Hari, Music Week, Disraeli, The Lion, The Witch, and the Wardrobe, The Times, the Animals "House of the Rising Sun", The Washington Post, The Indian Times, Tarzan, and Crocodile Dundee.
Goofs: Sam claims to have been in revolutions before, but unless it's an unrecorded adventure, she hasn't.
Dialogue Triumphs: "I never saw any incident where the violent solution was the best one."
Continuity: The drug Om-Tsor is actually Rubasdpofiaew, a powerful telekinetic used by the nonsentient brasdpods of Tau Ceti Minor to help them catch their food. It is a type of plant, with flowers that have butterfly-shaped petals. It causes boiling water to freeze on contact. Ed found it in the village of Ghumding in Nepal, but it originated from the monastery in the high valley of Om-Tsor. The monastery was named after the plant, and was established by lamas who discovered it and named it Om-Tsor, which means Miracle Flower. When the Chinese invaded, the lamas burned the plant to prevent it from falling into their hands. It allows humans to cause serious telekinetic damage. The Revolution Man, a.k.a. Jean-Pierre Rex, uses Om-Tsor to carve his symbol in the Great Pyramid, the snows of Austria, both towers of the Golden Gate Bridge, the floor of the St Peter's Cathedral, and Red Square. Ed Hill murders Rex when he starts to doubt whether he's doing the wrong thing, and adopts the title of Revolution Man in his stead. His and others' misuse of Om-Tsor brings the world to the point of nuclear war, and would have destroyed it completely on 18th May 1969, until the Doctor takes Om-Tsor and uses it to avert the disaster, also apparently untangling the impact on the Vortex in the process [and therefore possibly changing history in the process].
The Doctor drinks coffee and identifies that, despite claims, it doesn't come from Havana. He and Sam have at least forty-seven pre-prepared escape moves. He gives Sam a small, jewelled brooch that measures spatial distortion. He claims, not entirely untruthfully, that he, Sam and Fitz are psychic investigators. He gives Sam a leather wallet containing contemporary Italian currency. He hangs an "Out of Order" sign on the TARDIS whilst in London (see The War Machines). He again uses the alias Dr. John Smith, this time to bail Sam out when she gets arrested in Rome. He rides a motorbike again here (The TV Movie). He leaves Sam a voice box message on a telephone number in Kent (see Cat's Cradle: Warhead, Warlock, Warchild etc). He claims to be working for UNIT in 1968. He shoots Ed Hill dead after Fitz's shot leaves him brain damaged and his Om-Tsor-induced psionic powers hopelessly out of control.
Sam has read Jean-Pierre Rex's The Anarchy of the Future and The Liberated Mind and was looking forward to meeting him until she discovers that he advocates violence. She drinks a cappuccino in Rome [when did she start drinking caffeine?]. Her parents Allen and Margaret may have been at the East Worldham pop festival in June 1968. She infiltrates the Total Liberation Brigade by claiming to be a runaway. She also tells them that the Doctor has connections because he is a viscount. He has been teaching her meditation techniques. She has a twenty-third century bed in her room that changes size to fit all humans and several humanoid species, possibly including Earth Reptiles and Draconians. She is horrified by the Doctor's execution of Ed Hill, for which she blames Fitz.
Fitz wears an overcoat. He has been practicing escape manoeuvres with Sam. He eats bacon and eggs with Maddie. He is rather half-heartedly attempting to quit smoking. He takes Om-Tsor in Tibet. He is captured by the Chinese People's Army and brainwashed into serving Mao Tse Tung's regime; the brainwashing starts to wear off when he returns to England. He gets a haircut whilst in China. He shoots Ed Hill in the head. Fitz actually spends a total of two years here away from the Doctor, due to the Doctor hopping forwards repeatedly in the TARDIS.
The VW Beetle is still in the TARDIS. The Doctor apparently acquires a motorcycle here, which he parks next to it.
Links: Fitz recalls the Vega Station (Demontage). Sam admits that she has killed (Genocide) and recalls meeting Vampires in Los Angeles (Vampire Science). She also recalls Zygons (The Bodysnatcher). The Doctor mentions Yetis in the Underground (The Web of Fear) [he dates the events of that story to 1969 or 1979, but notes that his memory of it is blurred due to the length of time since it happened to him].
Location: The Vale of Kashmir, India; Rome, Italy; and London, June 1967; the East Worldham pop festival; London and Tibet, in June 1968; Ramsgate and China, February 1969; Paris, May 18th 1969.
Unrecorded Adventures: Sam bought her new boots in a corner shop on the fringes of a desert on a planet with a bloated red sun and a sky dotted with space stations. She may have encountered Selachians (The Murder Game, The Final Sanction) [although they were mentioned in Alien Bodies, so she might just have been told about them].
The Doctor attended Fidel Castro's funeral in Havana. He stayed on Gaby's World for a while around the time of his eight hundredth birthday, a planet that is always chilly and always cloudy on the little islands around the pole. It is inhabited by the Jympyns, which are grey, and jelly-whales.
The Doctor was a friend of Mao Tse Tung before Mao rose to power: he doubts the paranoid older Mao would listen to him now (see The Mind of Evil).
The Bottom Line: "He's a hero! And he never never does anything wrong - you don't understand!" Revolution Man occasionally functions as an interesting counterpoint to several New Adventures by condemning anarchy and the hypocrisy of many peace activists, whilst also doing interesting things with the relationships between the TARDIS' crew: there's a distinct feeling that, after the Doctor kills Ed Hill, Sam will never look at him in the same way again. Despite all that though, this is Paul Leonard's least effective Doctor Who novel, filled with fundamentally annoying supporting characters, a surprisingly dull plot and Sam at her most irritating in quite some time.
