Cold Fusion (novel)

Cold Fusion was the twenty-ninth novel in the Virgin Missing Adventures series. It was written by Lance Parkin. It was the only multi-Doctor story involving televised Doctors ever told by Virgin Books. It involved the unusual pairing of the season 19 Fifth Doctor with the Seventh Doctor near the end of the Virgin New Adventures line.

Originally intended to be published alongside PROSE: So Vile a Sin to emotionally leverage Roz Forrester's death in that book, delays on Sin meant that people who read the book on publication didn't see this intended aspect of the book.

As a multi-Doctor story, its perspective was unusual. The Seventh Doctor was portrayed as largely disdainful of his earlier self's presence because of the dangers it presented. Though temporal paradoxes and other consequences of two Doctors meeting were touched upon in televised multi-Doctor stories, here they were more central. Moreover, the structure broke with the format of televised multi-Doctor stories, which held that the latest incarnation was the "current" Doctor and therefore the effective headlining "star" of the show. On balance, Fusion was a Fifth Doctor novel that happened to feature the Seventh, rather than a Seventh Doctor novel that used the Fifth.

Publisher's summary

 * "The entire universe is at stake and I'm locked in here with another incarnation of myself, and not even one of the good ones!"

More than one TARDIS lands on a barren ice world. The Fifth Doctor, Adric, Nyssa and Tegan find a once ordered society on the verge of collapse, as rebels wage a dirty war with Scientifica, the ruling elite. All that stands between order and anarchy is the massed presence of an Adjudicator peacekeeping force.

But is peace the only reason for the Adjudicator garrison? What exactly has been discovered deep below the planet's surface? Who are the mysterious Ferutu? And why is telling a ghost story a criminal offence?

The Fifth Doctor sides with the cause of justice and fairness as always. But, as a threat to the universe unfolds, he finds himself in conflict with his past... and his future.

Cultural references from the real world

 * Tegan has seen Blake's 7 and can cope with the idea of transmats.
 * The statement from the Train Computer, "The lever you have pulled – 'Brakes' – is not in service. Please make a note of it", is a reference to an episode of The Simpsons called "Marge Vs. The Monorail", where Homer's attempts to brake an out-of-control monorail are met with the same response.
 * On page 142, the line "The birds sing a pretty song and there is always music in the air..." is likely a direct reference to episode 2 of the American TV show Twin Peaks.

Species

 * The Ferutu are beings from an alternate universe in which Gallifrey was destroyed shortly after Omega's experiments; they have assumed the role of the Time Lords, and actively engage in protecting and shaping the universe. Their "technology" (if it can be called that) is more akin to magic runes.

 * This story begins a series of story arcs known as the "Psi Powers" arc for the Seventh Doctor, continuing in PROSE: The Death of Art and ending in PROSE: So Vile a Sin
 * The Fifth Doctor is still recovering from the effects of his regeneration three days earlier. (TV: Logopolis, Castrovalva)

 * Tegan reminds the Fifth Doctor that she never got the chance to be an air hostess. (TV: Logopolis)
 * Adric mentions that the Keeper of Traken was able to divert the TARDIS' course. (TV: The Keeper of Traken)
 * The Doctor reminds Adric that the Master supposedly died on Castrovalva. (TV: Castrovalva)
 * Adric has only known the Doctor for several weeks. They first met on Adric's homeworld Alzarius during the 32nd century towards the end of the Doctor's fourth incarnation. (TV: Full Circle)
 * Chris refers to Serenity, the last surviving planet of the Traken Union. The Sixth Doctor and Peri Brown visited it on one occasion. (AUDIO: The Guardians of Prophecy)

 * The Seventh Doctor remembers the events of the novel from the perspective of the Fifth Doctor and uses this knowledge against his younger self. This also occurs in AUDIO: Peri and the Piscon Paradox, AUDIO: The Four Doctors and TV: Time Crash in which the Sixth, Eighth and Tenth Doctors respectively likewise remember the events portrayed from the point of view of their fifth incarnation.
 * The Seventh Doctor describes his fifth incarnation as being "bland" and "not even one of the good ones." This reflects the Sixth Doctor's low opinion of his immediate predecessor immediately after his regeneration as he told his companion Peri Brown that "he had a feckless charm that was never really [him]." (TV: The Twin Dilemma) The Eighth Doctor was more fond of his fifth incarnation than his two immediate predecessors. He once described him as "terribly polite." (AUDIO: The Four Doctors) By the time of his tenth incarnation, the Doctor expressed a fondness for his time as the Fifth Doctor. He looked upon his fifth incarnation as a turning point in his life. According to the Tenth Doctor, it was during his fifth incarnation that he truly began to enjoy himself. (TV: Time Crash)
 * The Fifth and Seventh Doctors would later meet each other again in AUDIO: The Sirens of Time, prior to the events of AUDIO: The Veiled Leopard and briefly in their eighth incarnation's TARDIS in AUDIO: The Four Doctors, though neither retained any memory of that experience.
 * Bernice Summerfield would later encounter the Ferutu on Dellah in 2596. (PROSE: Twilight of the Gods)
