Third (in the prologue and epilogue only).
Jo Grant (in the pologue and epilogue only), The Brigadier, Sgt Benton, Mike Yates, Ian Chesterton, Barbara, Harry Sullivan.
The TARDIS rematerialises in the UNIT laboratory post-Curse of Peladon at the novel's conclusion.
Inferno, The Dark Path.
Pg 1 "The British field headquarters of the united Nations Intelligence Taskforce at Denham" UNIT's HQ is here in The Scales Of Injustice. Also, it's where at least one of the houses used as a location by the BBC is.
"The only person on duty at the front desk at this hour was Sergeant John Benton." Sgt. Benton was given a first name in the Reeltime Pictures 'Wartime' video.
"Mike Yates is taking me to see the new Woody Allen film." This is a reference to the date that Jo was dressed up for at the beginning of The Curse of Peladon.
Pg 2 "Although the wide six-sided electronic toadstool belonged inside the TARDIS, the Doctor had recently removed it" The first time the console was seen outside of the TARDIS was in The Ambassadors of Death. It was also outside in Inferno and Day of the Daleks.
"The last time she had followed him into the TARDIS, it had whisked her off 500 years into the future." Colony in Space. A calendar on the wall shows it to be 2472.
Pg 3 "We'll be back the instant we left, like on our trip to Exarius." Colony in Space.
Pg 7 DI Boucher is named after Chris Boucher, writer of The Face of Evil etc.
Pg 21 "The last time the Doctor had vanished, the Time Lords had returned him immediately, and something similar had happened when he took Axos away from Earth." Colony in Space, the Claws of Axos.
"However, the Brigadier was beginning to think more in terms of the
four-year gap between his battles with the Yeti and the Cybermen; or the two years after that when he had turned up just as those Nestene things launched their first attack." The Web of Fear, The Invasion, Spearhead from Space.
"What was he supposed to tell her uncle at the UN?" In the novelisation of Colony In Space, Jo was given an alternate origin story involving her uncle being an important bureaucrat. This story has been stuck to, most notably in Blood Heat.
"As Doris had told him, at least things were quiet for the moment" The Brigadier's wife in Battlefield in 1997, first mentioned in Planet of the Spiders.
"He had just gotten used to the idea of being with someone again and didn't want worries about his job to jeopardise things. He wasn't sure he could take that again, not so soon." The Brigadier recently divorced his first wife, Fiona, in The Scales of Injustice.
Pg 27 "Stretcher party on the double, Captain. we're not too far from Ashbridge, are we?" When the TARDIS landed in Spearhead from Space, the traumatised 3rd Doctor was taken to Ashbridge Cottage Hospital.
Pg 29 "Henderson was one of the few medics who had had experience with aliens, having treated the Doctor when he arrived back on Earth." Spearhead from Space.
Pg 30 "Greyhound to Trap Two." UNIT callsigns used for most every remote conversation between the Brigadier and his officers. Trap two is the mobile HQ.
Pg 31 "Mike Yates was able to snatch a quick cup of coffee and a corned beef sandwich before the Brigadier returned to his office." Likely a reference to episode 1 of The Daemons, when Sgt. Benton lamented that the Brigadier was off to a dress function while himself and the lads were stuck a headquarters watching the football results with a pile of corned beef sandwiches.
"I wondered if we ought to bring Miss Shaw back in?" Liz Shaw, former scientific advisor to UNIT.
"She had worked well enough when she had been brought back after her leave of absence following the business at the Glasshouse." Liz apparently left UNIT after a fiasco involving Earth Reptiles (Silurians) and the Glasshouse in The Scales of Injustice. The Devil Goblins from Neptune may have been set after that, if indeed Liz had only taken a leave of absence. The Glasshouse later became controlled by the Master in Who Killed Kennedy.
Pg 32 "I tried to reach Anne Travers." Professor Travers' daughter, seen in The Web of Fear and Millennial Rites.
"I'm still waiting for a reply from Rachel Jensen." Scientific Advisor to the Intrusion Counter Measures Group in 1963 in Remembrance of the Daleks.
"That chappie from the British Rocket Group." Rachel Jensen referred to the Group in Remembrance and also seemed to name Professor Bernard Quatermass. The Devil Goblins from Neptune confused matters by introducing Professor Bernard Trainor of the BRG. However, Trainor was killed off, so the Brigadier isn't querying his availability here.
Pg 42 "This is my wife Barbara." It was established in Timewyrm: Revelation, among other New Adventures, that Ian and Barbara got married after returning to 1965 London.
Pg 43 "That year-long exchange programme to NASA" The novelisation of The War Machines explained the first Doctor's accorded access to the GPO Tower and WOTAN's control room by mentioning that his friend Ian had become a consultant in the American moon missions. The ground was prepared for Marter's explanation by the alternative origin story of David Whitaker's novelisation of The Daleks in which Ian was a rocket scientist and not a science teacher.
Pg 48 "Between them they had been materialised, dematerialised, flown in rockets, jumped time tracks - you name it." Ian and Barbara flew in actual spacecraft from Earth and the Sense-Sphere in The Sensorites and jumped a time track in The Space Museum.
Pg 49 "Look, d'you want to go home and check up on John?" It was also established in Timewyrm: Revelation that Ian and Barbara had a son John. John grows up to become the rock star Johnny Chess, seen briefly in The King of Terror and Byzantium!. But see Continuity Cock-Ups for one of the great ones.
"Joseph Barron had always wanted a big house in the country; something like Mick Jagger's place, maybe." The Jagger mansion, Stargroves, was used as a filming location for The Pyramids of Mars and Image of the Fendahl.
Pg 51 "The Aylesbury Grange Detention centre wasn't officially a prison." Aylesbury Grange (and Dr Conran) are from the DWM UNIT special comic strip Man In The Ion Mask.
Pg 53 "You're looking well for someone in prison, Mr Magister." The Master's assumed identity in The Džmons.

Pg 73 "Like the one the Daleks ' poisoned atmosphere had left on them." The Daleks.
Pg 78 "Or is he Swiss, like Emil Keller? Rhodesian, perhaps, like Colonel Masters?" The Mind of Evil, Terror of the Autons.
Pg 82 "The two Jimmys, Turner and Munro, were both in town." Captain Turner was one of the Brigadier's officers in The Invasion. Captain Munro was under his command in Spearhead from Space.
Pg 88 "When he first started causing us trouble, he hypnotised Jo - the Doctor's assistant - into bringing a huge bomb into the lab." Terror of the Autons.
Pg 91 "What might the Aztecs have been if Cortes hadn't been so offended by the sacrifice rites?" The Aztecs.
Pg 92 "You'd think they'd have learned their lesson after putting him on remand at Stangmoor before his trial." Forward reference to the then unpublished Short Trips story Freedom.
Pg 93 "Presumably Fortress Island would be more fitting when its refurbishment was complete." The Master's prison in The Sea Devils.

Pg 144 "Ironically, that moderation was one of the things that had persuaded Fiona to marry him in his pre-UNIT days." Fiona was first mentioned in Downtime.
"He despaired of ever really understanding them." In Battlefield the Brigadier complained that he didn't understand women.
Pg 149 "He caught himself in time, and suppressed the anger. It would be his undoing some day, if ever he was undone." This might be a reference to Survival.

Pg 171 "In fact the design methodology almost looked like Dalek circuitry." Day of the Daleks.
Pg 178 "It was a dozen years ago, but the effects of that first shot from a Dalek weapon had never faded from his memory." The first ever shot a Dalek fired onscreen was to paralyze Ian's legs in Episode 2 of The Daleks. However, Ian says it as if he had been shot by the Daleks more than once.
Pg 180 "We had met the Daleks, and Voord, and Zarbi..." The Daleks, The Keys of Marinus, The Web Planet.
Pg 181 "The Doctor did, if his goodbye to Susan was anything to go by." the Dalek Invasion of Earth.
Pg 185 "She would probably have confessed to half-expecting a couple of Voord or Robomen to come round the corner. Or Venusians, perhaps." The Keys of Marinus, The Dalek Invasion of Earth, Venusian Lullaby.
"You didn't need to be James Bond to teach O level history at the local comprehensive." This is very similar to the Brigadier's line about teaching mathematics in Mawdryn Undead.
Pg 186 "It would be easier if we could simply adapt a TARDIS's time-path indicator." The Doctor used the time-path indicator to detect the Dalek time-machine following the TARDIS in The Chase.
Pg 189 "He had in the past wondered how he might cope if Doris or his daughter, Kate, were to die unexpectedly." This probably isn't a reference to The Shadows of Avalon, since it was a long way from being published when this book came out. Kate was seen in Downtime.
