The Mysterious Planet was a novelisation based on the 1986 television serial The Mysterious Planet.
The TARDIS has been taken out of time and the Doctor has been brought before a court of his fellow Time Lords. There the sinister Valeyard accuses the Doctor of breaking Gallifrey's most important law and interfering in the affairs of other planets.
If the Valeyard can prove him guilty, the Doctor must sacrifice his remaining regenerations. To prove his case the Valeyard focuses on an adventure set in the Doctor's past.

Deviations from televised story
- Valeyard, like Inquisitor, seems to be a Time Lord title, a Special Prosecutor assigned by the High Council in serious, often political, cases.
- The Doctor informs Peri they are currently two million years or more after her time period, while in the televised version it is not explicitly clear whether the Doctor said "two million" or "two billion."
