Together with Sarah and Harry, the Doctor finds himself stranded on the
war-torn planet Skaro where the conflict between the Thals and the
Kaleds has been raging for a thousand years. Chemical and biological
weapons have started a cycle of mutation among the planet's inhabitants
that cannot be stopped. But Kaled scientist Davros has perfected a life
support system and travel machine for the creature he knows his race
will ultimately evolve into -- the Dalek. The Doctor's mission is to
stop the creation of the Daleks! This novel is based on a Doctor Who
story which was originally broadcast from 8 March-12 April 1975. This
title features the fourth Doctor as played by Tom Baker with his
companions Sarah Jane Smith and Harry Sullivan.
