The listing, Doctor Who and the Cybermen has ended.
Originally broadcast in 1967 as THE MOONBASE, DOCTOR WHO AND THE CYBERMEN sees the return of the Cybermen in their second appearance and their first appearance with the Second Doctor, who would go on to fight them again in THE TOMBS OF THE CYBERMEN (1967), THE WHEEL IN SPACE (1968) and THE INVASION (1968). Although their second appearance here holds more historical weight as the Doctor confronts the Cybermen again after his first regeneration - this a minor point in the novel and may go a long way in explaining why the Doctor has some trouble accepting the Cybermen have returned even though Polly (who calls the Cybermen out early) clearly knows what a Cyberman is (having fought them, alongside Ben, in THE TENTH PLANET), the Doctor seems reluctant to totally take her word for it...maybe because it brings up very bad memories for the Doctor?, or maybe the Doctor thinks Polly is just being too much of a girl.
