In this thrilling adventure - the start of the 'Trial of a Time Lord' story arc - 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. It is an adventure set on the planet Ravolox, a seemingly primitive world but one which the Doctor and Peri find strangely familiar... Lynda Bellingham, who played the Inquisitor in the Doctor Who serial The Trial of a Time Lord, reads Terrance Dicks' complete and unabridged novelisation, first published by Target Books in 1988.
