Martin Jarvis reads this exciting novelization of a classic TV adventure
introducing the slug-like Sil. The TARDIS has stalled in mid-flight, and
it is only on the planet Varos that the Doctor can find the precious
Zeiton-7 ore he needs. Arriving on the planet, he saves the rebel Jondar
from execution, and incurs the wrath of Sil, the sadistic representative
of the Galatron Mining Corporation on Varos. As the Doctor and his
friends are pursued through the corridors of the deadly Punishment Dome,
the Doctor discovers that the people of Varos have some very disturbing
ideas of entertainment.
