Blood Heat

Roots: Planet of the Apes. The novel opens with a quotation from J. A. Froud. There are references to Sherlock Holmes, Mills & Boon, Ford Cortinas, Von Zeppelin, Meccano, Hitler, Sooty and Sweep, Lego, Schubert's "Unfinished Symphony", Batman, and Peter Pan. Ace dubs the Rover "Ivor" after Ivor the Engine. The names of the Silurians in The Silurians are taken from Malcolm Hulke's novelisation Doctor Who and the Cave Monsters - Blood Heat generally owes more to the novelisation than to the TV story.

Goofs: The Silurians is dated to 1973, which contradicts the dating used by The Discontinuity Guide and adopted here.

Artistic license rather than a goof, but scenes shown in flashback from The Silurians are altered to incorporate the Silurian names from Hulke's novelisation. Notoriously, the dark cloak worn by the corpse of the Third Doctor is also not what he was wearing in the original story [but this is set in a parallel universe - ed].

If the Doctor can materialize the TARDIS around entire planets to stop weapons working and halt wars, why hasn't he done it before or since?

Dialogue Disasters: 'Come and take your medicine you damn... bullies!'

Dialogue Triumphs: 'Yes, they're intelligent. Yes, they're civilized. But they still hunt us. From choice. Because they enjoy it.'

Continuity: The entity that allows Morka to kill the Third Doctor and thus change history is used to a space with more physical dimensions than those of normal space. It is revealed to be a Chronovore under the control of the Meddling Monk in No Future. The Monk uses it to allow Morka to kill the Third Doctor and prevent him from regenerating in order to change history, since he was unable to find a cure for the Silurian plague with which Major Barker was infected. Morka killed the Doctor on the tenth day of his incarceration. Because the universe only has a finite amount of mass and energy, the creation of the alternate timeline adversely affects the real timeline, causing chaos throughout the universe; the Doctor uses the TARDIS from the alternate timeline to time-ram the TARDIS in the tar pit, releasing enough energy to destroy the alternate timeline and set history back on its correct course. He, Ace, and Bernice, continue their travels in he TARDIS from the alternate timeline (see The Time Monster).

The accurate scientific name for the Silurians is psionosauropodomorpha, at least according to the Doctor. They are telepathic, which is how they communicate with each other and with dinosaurs, a process that they describe as "linking". They can kill using telekinesis; both telepathy and telekinesis depend on their third eye. Their main city Ophidian is on Earth in the alternate timeline is in east Africa, on the equator. There is a Museum of Silurian Culture to the north of the Palace. They have renamed the Indian Ocean "Tethys". They also have a citadel in Glasgow. Humanity's cities are left ruined and abandoned. The Silurians get their energy by induction from geothermal power from installations at the poles; as a consequence, the ice caps are melting, causing rising water levels all over the Earth. They have been terraforming Earth back to how it was when they ruled it, and repopulating it with dinosaurs and prehistoric plant life. They have weather control technology, and can open gaps in the atmospheric blanket over specific areas of the Earth, letting unfiltered sunlight through. With the Doctor dead, the Silurian plague wiped out huge numbers of humans, and the Silurians woke their brethren from shelters all over the world. The surviving humans in this time-line refer to the inherent fear of Silurians in humans as the "race memory malaise". They refer to the Silurian plague, and the ensuing war, as the Nightmare. Packs of feral dogs carrying mutated rabies run wild in the ruins of London. The Silurians use massive airships for transport as well as pterosaurs. Silurians don't have literature, because they find the direct communication of ideas by telepathy more accurate, stimulating, and attractive. The Young Silurian is named Morka; he is now leader of the Silurians (The Silurians). The Old Silurian was named Okdel. Military Liaison Icthar heads the Council for Operations (Warriors of the Deep, The Scales of Injustice).

The Doctor carries a brand-new tennis headband in his pocket and a bottle of aniseed. He also produces from his pockets two rounds of hot bacon sandwiches, a Mars bar, and a litre carton of fresh chilled orange juice. He can telepathically link with Silurians. The pockets of the cloak found on the corpse of the Third Doctor contain a yo-yo, the sonic screwdriver, a couple of vacuum-formed valves, a 1957 half-crown, three marbles, a key ring with four keys attached, and the TARDIS key on a chain. "You see all those stars? Each one of those represents a promise. All the time they shine the promise remains unbroken" is a Gallifreyan saying.

Ace carries redesigned nitro nine smart bombs. In her jacket pocket she carries a stale bar of chocolate, a crumpled paperback book, three missing pieces from a jigsaw puzzle that she tried to complete a month earlier, and a box of matches. She once visited the City Farm with school. She has a Hillman Avenger vanity plate in her satchel. She has a scar from a plasma burn from a Special Weapons Dalek across her stomach. She kisses Alan, and notes that when she does so she closes her eyes during a kiss for the first time in her life. In the alternate timeline, Ace died at the age of seventeen. Ace reconfigures a new room for herself in the alternate TARDIS.

Benny uses part of the TARDIS as a laboratory and is currently trying to preserve an Alexandrian scroll. Morka infects her with a viral serum from her own brain once her race fear is overcome, hoping to eliminate the race memory malaise in humans in an attempt to establish peaceful coexistence between the two species. She gets shot, and has to have a bullet removed from her lung.

The Brigadier was born in 1933. In the alternate timeline, he organizes a resistance movement against the Silurians based at Cheddar Gorge that includes Benton, Meredith (The Silurians), and Liz Shaw. His wife was killed by the Silurians.

In the alternate timeline, Jo Grant is pregnant by 1993; she has a stillbirth followed by haemorrhage and septicaemia as a result of being hunted by the Silurians. Her uncle General Hobson entrusted her with a copy of Hemingway's The Old Man and the Sea in 1973; it is actually a disguised copy of the Computer Control Related Missile Launch Protocol Manual carrying instructions on how to fire nuclear missiles from a submarine. Liz Shaw has been married and widowed. Her husband was named James Lester and died whilst hunting for food when he tripped and hit his head on a tree; after his death, she went back to using her maiden name.

The events of Birthright caused a personality schism in the TARDIS. The console room has a wood paneled ceiling [is the Doctor currently using the secondary console room? See The Masque of Mandragora]. The console room contains a chaise longue, which vanishes when the TARDIS enters the alternate timeline. The TARDIS is knocked into a tar pit by an edmontonia and is lost. The TARDIS in the alternate timeline went into internal shutdown when the Doctor died. The Doctor materialises this alternate TARDIS around the whole Earth, immobilizing the Brigadier's nuclear weapons because of the state of temporal grace inside the TARDIS; he then uses the architectural configuration circuits to delete the areas of the TARDIS containing the missiles (see Logopolis). There is a fire extinguisher in the TARDIS storeroom.

Ace's friend Manisha has a sister named Kosi. Manisha and Kosi are still alive in 1993 in the alternate timeline.

Links: The Silurians, The Sea Devils. Several months have passed since Ace left Spacefleet (Deceit). The physical disintegration of the TARDIS recalls that in Terminus. The HADS is still working (The Krotons). The Doctor notes that the TARDIS interior is supposed to exist in a state of temporal grace (The Hand of Fear). The Doctor mentions the Guardians (The Ribos Operation, The Armageddon Factor, Mawdryn Undead, Terminus, Enlightenment), Rassilon, and the Master. He convinces Liz of his identity by mentioning the Nestene Consciousness and the Autons (Spearhead from Space). Manisha was first mentioned in Ben Aaronovitch's novelisation of Remembrance of the Daleks, and again in Ghost Light and Timewyrm: Genesys; her surname was revealed in Timewyrm: Revelation.

Location: London, Bristol and Cheddar Gorge, England; Glasgow, Scotland; and Ophidian, on the African coast of the Indian Ocean; 1993, in an alternate timeline.

Unrecorded Adventures: The Doctor met Turner, who at the time had sprained his right hand falling down a flight of stairs.

The Bottom Line: 'Someone is playing games with me. Someone is meddling.' Although some of the moralizing about the horrors of war is occasionally a bit too heavy handed, Blood Heat is a gripping "What if?" story exploring the consequences of the Silurians reclaiming the Earth and what it would mean for humanity. There are some extremely moving scenes, and Mortimore makes a strong case for the argument that peace is the only way forward, despite the atrocities committed on both sides. And with an unseen foe manipulating the Doctor from behind the scenes, it's also an intriguing start to the Alternate Universe Cycle...

A drab slog. It started off all right with the traumatised alternative Jo and the knowledge of the alternative Third Doctor's death, but it was all very numbing after so many pages of UNIT and the Silurians committing war crimes followed by Liz demanding peace. As much as Mortimore tries to sell us on the idea both sides have their points, it's heavily slanted towards the humans; the Silurians are immensely brutal and we see far less from their point of view, making it much harder to sympathise with them. To top it off, nothing the protagonists do matters in the end, and the identity of the villain behind the history changes is blindingly obvious thanks to poor wording. It also sees the return of the giant chapters that Deceit had, a feature I hate. It was kind of nice having illustrations again though.
