Mission to the Unknown (novelisation)

 was a novelisation of the 1965 standalone episode Mission to the Unknown and episodes 1-6 of the 1965 serial The Daleks' Master Plan. The second volume, The Mutation of Time, adapted episodes 7-12. Not counting the four novelisations based on The Trial of a Time Lord, this marks the only instance of Target Books publishing an adaptation of a Doctor Who story in more than one volume. Mission to the Unknown, although linked to the main story, is officially considered a separate, standalone story by the BBC, making this volume the only occasion in which a Target novelisation actually adapted more than one serial.

1989 edition
Stranded in the jungles of Kembel, the most hostile planet in the Galaxy, Space Security agent Marc Cory has stumbled across the most deadly plot ever hatched-the Daleks are about to invade and destroy the Universe. Cory has to get a warning back to Earth before it’s too late-but the Daleks find him first.

Months later the First Doctor and his companions arrive on Kembal and find Cory’s message. But it may already be too late for Earth-the Daleks’ Masterplan has already begun…

Mission to the Unknown

 * Much of the dialogue is slightly different from the original version but the the information delivered is still the same - the wording is simply altered.
 * Lowery mentions the Movellan War when Cory asks him what he knows of the Daleks. The whole concept of the Movellans and their war with the Daleks was not part of the TV series until Destiny of the Daleks during the Fourth Doctor's era.
 * Peel mentions the Dalek Prime, an alternative of the Dalek Emperor for the never-produced War of the Daleks TV serial, also proposed by Peel. The Dalek Prime appeared briefly for the first time in Peel's previous novelisation, The Chase and would later do so again in his novelisation of The Evil of the Daleks (as the Dalek Emperor) and finally in the War of the Daleks novel and a mention in Legacy of the Daleks. Although the Dalek Prime is mentioned here, its second appearance would not happen until the second volume of the Master Plan novelisation.
 * Some of the descriptions of the delegates are apparently different from how they appeared on-screen. For example, Trantis is described as "a somewhat faceless creature with an egg-shaped head", even though on TV he has a fairly human appearance, save for his jagged teeth and eventual tendrils.
 * The final scene of the episode, in which the Daleks and the alliance chant "Victory!", is omitted and this part of the novelisation ends on the Daleks leaving Cory and Lowery's bodies. Instead, the next chapter return the action to the Doctor and Katarina as the TARDIS lands on Kembel, transitioning into the beginning of The Daleks' Master Plan.

The Daleks' Master Plan

 * Reference is made to the Daleks using taranium to power their time machines, something stated in Peel's novelisation of The Chase. It took the Daleks almost a century to acquire enough to power all the time machines in their Empire, but by 4000 they needed Mavic Chen's help to acquire more for the Time Destructor.
 * Peel mentions the Dalek Prime again but it is still yet to appear.

Writing and publishing notes

 * Features advert: “Are You buying Doctor Who Magazine?”
 * The story opens in Troy, picking up from the end of The Myth Makers. Since it also novelises Mission to the Unknown and the first half of The Daleks' Master Plan, the book includes the novelisation or partial novelisation of three different stories.
 * John Peel referenced earlier versions of Terry Nation's original scripts while working on this story. Most authors of Doctor Who novelisations (other than the writers of the original stories) did not have access to earlier version of the scripts.
 * The cover for the original Target Books edition featured the artwork of Alister Pearson.
