A Biography of the Doctor

The Third Doctor

Season Nine


The Doctor is experimenting with his dematerialisation circuit, when he accidentally creates a freak effect, where he and Jo meet themselves from later in their timestream. However, the Doctor is able to return things to normal fairly soon. Meanwhile, Sir Reginald Styles has been attacked by a guerilla, who vanishes before he can kill him. UNIT and the Doctor are assigned to protect him and investigate, as he is hosting a world peace conference. Searching the grounds, UNIT discover an injured guerilla, his weapon, and a black box. The Doctor discovers that the gun is an ultrasonic disintegrator and the box is a crude time machine. The Doctor starts fiddling with it, and the guerilla disappears, taken back to his own time. When the guerillas next attack, the Doctor and Jo are captured and end up in the guerillas' future. In this future, a bomb at the peace conference started a world-wide war. When the Daleks travelled back in time to invade Earth a century early, they had complete success. The guerillas travelled back in time to prevent the bomb by killing Styles. The Doctor makes them realise that the bomb was one of the rebels' own bombs. Returning to the present, the Doctor arranges for the delegates at the conference to be evacuated. He lures a force of Daleks and Ogrons into the peace conference venue, and a guerilla, who had been stranded in this time blows up the building. This action destroys the future that had been created.

When the Doctor and Jo return to the UNIT lab, they encounter their earlier selves, as the earlier Doctor fiddles with his dematerialisation circuit.

(This last scene was in the camera script, but not filmed. It appears right at the end of the novelisation and so probably happens at the end of the story.)

Reporter James Stevens had been investigating UNIT for a couple of years, believing it to be a very sinister organisation. Seeing the Brigadier on TV before the peace conference, he rushed to the venue, arriving as the delegates were being evacuated. HE was caught in the battle between UNIT and the Daleks and their Ogron servants. The Doctor saves him from death, and the Brigadier explains UNIT's true nature. The Doctor is very interested in Stevens' experiences, and deduces that the Master is freer than expected. He asks Stevens to thwart the Master's plan to prevent the assassination of Kennedy, whilst he makes plans to investigate the Master's freedom.

(Chapters 21-24 clearly start at the end of Day of the Daleks. The Doctor's trip to Fortress Island in The Sea Devils appears to be in response to what the Doctor learns in this story.)

The Doctor and Jo are working late when an intruder breaks into the lab to steal some of the Doctor's equipment. The intruder, Tuala, takes the circuits she is after and kidnaps Jo. The Doctor is unable to rescue Jo, but does discover that Tuala and her uncle Krashen come from the future he had recently destroyed (Day of the Daleks). They have been changing history, keeping people alive in return for vast sums of money. The Doctor realises that the paradoxes Krashen has been creating must be stopped. He eventually tracks down Krashen and tries to reason with him. However, Krashen activates his time machine and sends them back to a time where Jo and Tuala could easily meet themselves. The Doctor finishes tinkering with the device just in time. Krashen and Tuala are removed from existence, and those they had saved disappear.

(Jo recalls the events of Day of the Daleks as being recent, although the peace conference is definitely over. As the TARDIS is not working, it has to be before The Three Doctors.)

Jo arrives at UNIT to meet Mike Yates for a trip to the cinema. Being early, she visits the Doctor's laboratory. The Doctor claims that he has repaired the TARDIS and offers to take Jo on a trip, claiming that they will be able to return instantly.

(The book is said to be concurrent with The Curse of Peladon, and this scene recaps the start of that story.)


The Doctor appears to have got the TARDIS working, and takes a trip with Jo. The TARDIS lands on Peladon, a planet that is considering joining the Galactic Federation. The Doctor is mistaken for one of the delegates who are to decide whether Peladon can be allowed to join. The Doctor is accused of sacrilege, and sentenced to a fight to the death. Following this, the Doctor exposes the Arcturan delegate and a faction of the Pels as responsible for a number of incidents. The Doctor then leaves as the real Earth delegate arrives.

(The reason for this mission is that it prevents a Federation Civil War, which would later allow the Daleks to conquer the Federation with ease.)

A few days after the TARDIS leaves, there is a strange plane crash, the body of the pilot almost exactly matches a junior minister's. UNIT is called in, and the Brigadier calls in Ian Chesterton from the Air Force as a temporary Scientific Advisor. When UNIT call on the minister in question, they discover that he has been murdered. The following day, the Master escapes from Aylesbury Detention Centre. He arrives at UNIT HQ to give himself up in return for protective custody. He helps UNIT build a device to track the duplicates, who are using some kind of time travel technology. Meanwhile, Barbara Chesterton is kidnapped from UNIT HQ and apparently killed in a car crash. However, the Master and Ian manage to track some temporal disturbances to the Naval base at Faslane, which seems to be the centre of the infiltrators' activities. UNIT staff travel to the base, where they meet Surgeon-Lieutenant Harry Sullivan. Sullivan helps them find out where on the base the infiltrators have been hiding. The Brigadier, Ian, and the Master travel to the Inferno universe, where they rescue Barbara and disable the infiltrators' ability to travel between worlds. They then stop the infiltrators from getting away in a nuclear submarine, and recapture the Master.

The Doctor and Jo return to Earth, two weeks (Earth time) after they left and the Brigadier doesn't tell them what has happened since they left.

(This is at the same time as The Curse of Peladon. Five years have passed in the Inferno universe, though fewer must have passed in the "real" universe. The Master has not yet been transferred to Fortress Island. The Doctor and Jo have been away for about two weeks.)


The Doctor and Jo visit the Master, who is being held on an island prison. He appears to be safely under lock and key, but has actually hypnotised his guards. After their visit, the Doctor and Jo decide to investigate some recent sinkings of ships in the area. Both the Doctor and the Master deduce that the sinkings are due to aquatic Earth Reptiles. Both Time Lords end up in the Earth Reptiles' undersea base. The Doctor argues that the two species (humans and Earth Reptiles) can make peace, whilst the Master argues that humanity should be destroyed. Human depth charges cause the Earth Reptiles to side with the Master. The Master then attempts to help revive the Earth Reptiles, but the Doctor is able to prevent this. In the confusion, the Master escapes.

The Doctor gets the Brigadier to set up roadblocks to find the Master. The Master gets through one by means of hypnotism. However, the report reaches the Doctor, who realises that he must be going to Devil's End. He arrives just before the Master was due to leave. The intervention of Miss Hawthorne, the local white witch, produces some kind of telekinetic effect as the Master disappears in his TARDIS. The Doctor returns to his lab, where he meets his eighth self, who is searching for his memories. His future self tells him that he will end this incarnation no longer exiled and in a noble cause. Then the Master arrives, but the presence of the eighth Doctor confuses him and he then retreats. The two Doctors then leave, but the Third Doctor almost tries to steal the eighth Doctor's TARDIS. He decides not to, and returns to his work at UNIT.

(The third Doctor segment clearly takes place immediately after The Sea Devils.)

Late at night, the Doctor is experimenting on the dematerialisation circuit when he is interrupted by the Brigadier. The circuit leaps into the air, and the sensor probes connected to it are flashing manically and urgently - filling him with instant dread. The next day, the Doctor and Jo set off for Princetown, Dartmoor, where the sensor leads them. They watch a Punk band play, and see the audience murder three prison officers and a policeman. Two days later, they see the band's second performance, when 3 fox-hunters are murdered. Throughout both performances, the sensor is highly active. The Doctor leaves Jo - who, like the rest of the audience, has been entranced by the Band with a group of fans and returns to UNIT HQ. He attempts to isolate the source of the signals he has been receiving, and asks the Brigadier to send an undercover UNIT operative to the convoy now following the band to keep an eye on Jo.

Five days later, the Doctor is still working on the problem, the Brigadier assigns Mike Yates to check on Jo, and the Prime Minister - under pressure from tabloids and the opposition - orders that UNIT replace the police in shadowing the convoy.

An indeterminate time later, the Doctor tracks down the second signal - the first had been coming from the trailer the band are in, the second he discovers to coming from a gruesome book in a library in the village of Cirbury. He then goes to investigate the trailer in which the band are hidden, and finds himself stuck in a hellish world of the imagination. He discovers something of the history of the instigator - a being calling itself the Ragman. He eventually finds a way out, just as events reach their peak. As the Brigadier battles some of the convoy at Stonehenge, the Doctor manages to defeat the Ragman - releasing everyone from its spell. This is due to revealing its true nature to some of its followers.

(Jo mentions Ogrons from Day of the Daleks, and it's clearly before The Three Doctors. The Brigadier's comment about the Doctor sneaking off in the TARDIS may be a reference to Colony in Space. However, it is more likely a reference to his extended absence in The Curse of Peladon / Face of the Enemy. It takes place during May and June.)


The Doctor is building a minimum inertial superdrive for Bessie when he receives a message capsule from the Time Lords. Realising that it is not for him, he takes a trip in the TARDIS. He and Jo arrive on a space station orbiting the planet Solos in the 30th Century. Solos is part of the Earth Empire, which is planning to let Solos become independent. Large numbers of native Solonians are mutating, and the humans are trying to kill the mutants. The Doctor discovers that the message is for Ky, one of the Solonians, and it is written in ancient Solonian hierographs. The Doctor discovers that the Solonians naturally mutate every 500 years, and that human experiments on Solos's atmosphere have interfered with the process. The Doctor manages to decontaminate Solos's atmosphere. In the course of events, the humans responsible for the damage are killed, and the Doctor and Jo return to Earth in the TARDIS.

(It is never made clear why the Time Lords want the Doctor to travel to Solos.)

The Secret Vote Finance Committee decides that the UK branch of UNIT costs too much. They decide that UNIT UK's activities can be carried out more cheaply by the Royal Marines. Meanwhile, the Doctor has been tracking a missing government minister. He discovers that the minister was killed by a Birastrop called Dantallion. Dantallion had been dissecting humans in order to treat other humans in the future. Although the Brigadier tries to pull strings to save UNIT, he is unsuccessful. The Doctor decides to ask the Time Lords to let him pilot the TARDIS in a plan to save UNIT. He abducts Dantallion from the Marines and gets him to sign over his mansion to the Doctor, before letting him leave the planet. The provision of a rent-free headquarters for UNIT and the Marine's failure allow the Brigadier to successfully fight for the continuation of the UK branch of UNIT.

(This is clearly before The Three Doctors, as the TARDIS isn't working yet. The Doctor mentions his mission for the Time Lords on Solos in The Mutants. UNIT moves headquarters from central London to a country manor.)


The Doctor decides to build a device to find the Master. Whilst working on this, he has a dream involving the Master, and when Jo mentions Atlantis, he connects the two. He then detects a disturbance in the time field related to TOM-TIT, a device of which the Brigadier is due to see a demonstration. The Doctor arrives at the demonstration, and discovers that the Master is behind TOM-TIT. He also learns that TOM-TIT relies on the Kronos Crystal, which contained a trapped Chronovore named Kronos. To try and stop the Master, the Doctor materialises his TARDIS inside the Master's. This causes the Master's TARDIS to also be inside the Doctor's. The Master separates the two, sending the Doctor into the vortex, although he survives. The Master then travels back in time to Atlantis, and the Doctor and Jo follow him there. The Doctor decides to time ram the Master's TARDIS to stop the Master from using Kronos's power, but cannot as this would kill Jo (who the Master has captured). However, Jo is able to make the decision for him. In the event, this does not cause any damage because Kronos intervenes, the Doctor and Jo return home but the Master escapes.

The Doctor and Jo take a holiday at a country house the Doctor owns. However, they discover Iris Wildthyme and her companion Tom visiting. Soon afterwards, a railway carriage full of 18th century people materialises in a nearby field, marauding robot sheep, and the total disappearance of UNIT. The Doctor and Iris discover that events are being orchestrated by aliens who have disguised themselves as fictional characters. Eventually, it is revealed that events have been orchestrated by a being Iris once asked to help set the Doctor free from his exile. The being, called Verdigris, had attempted to remove UNIT as it felt that the Doctor's work for UNIT was hindering his attempts at repairing the TARDIS.

(The Doctor mentions The Sea Devils, and it is clearly before The Three Doctors, as the Doctor is still an exile.)
