That charisma and anti-Establishment mind-set were transferred in 1963 to Doctor Who, his spiritual successor. Though pitched at children, this series bore many of the same characteristics, infusing sci-fi with a gothic aspect. Both these shows were often less Isaac Asimov and more Mary Shelley. In Quatermass, the fate of Victor Caroon - Quatermass's astronaut, brought back to Earth with an alien infection, who soon becomes a haunted wasteland-dwelling fugitive - has very strong echoes of Frankenstein. At the climax of Quatermass and the Pit, a vast flickering image of a horned demon hovers in the night sky over London. In the second serial of Doctor Who, the doctor's companion, Barbara, is pursued through a weird, deserted alien citadel by something unseen by us but clearly so appalling that her scream echoes over the closing music. It is, of course, a Dalek.
