Plot

Derbyshire, 1979. A legendary giant white worm is sought after by the Doctor, Leela and the Master.

Cast

• The Doctor – Tom Baker
• Leela – Louise Jameson
• The Master – Geoffrey Beevers
• Colonel Spindleton – Michael Cochrane
• Demesne Furze – Rachael Stirling

Continuity

• Geoffrey Beevers played the Master, alongside Tom Baker as the Fourth Doctor, in the 1981 television story The Keeper of Traken.
• The Fourth Doctor also encountered the Master in The Deadly Assassin and Tom Baker's last television story, Logopolis.
• The version of the Master that Beevers plays has an emaciated, corpse-like appearance. This was first seen in The Deadly Assassin, although in that story, the Master was played by Peter Pratt.
• For the Doctor and the Master, Trail of the White Worm takes place between The Deadly Assassin and The Keeper of Traken.
• The Doctor notices that the Master looks different, less emaciated, reflecting the differences in appearance in The Deadly Assassin and The Keeper of Traken. This may have been a result of the aborted rejuvenation at the end of The Deadly Assassin.
• Beevers previously reprised the role of the Master in two Big Finish audios, Dust Breeding and Master, both with the Seventh Doctor. In those dramas, the Master had reverted to his former deteriorated state, after losing the form he gained at the end of The Keeper of Traken.
