Why do so many spaceships crashland on Karn, a bleak, lonely and seemingly deserted planet? Are they doomed by the mysterious powers of the strange, black-robed Sisterhood, jealously guarding their secret of eternal life? Or does the mad Dr Solon, for some evil purpose of his own, need the bodies of his victims? And more especially, the body of Doctor Who... Tom Baker, who played the Fourth Doctor in the BBC TV series, reads Terrance Dicks’ complete and unabridged novelisation, first published by Target Books in 1977. ‘BBC Audiobooks has chosen well with its books and has taken the right approach with its readers... they benefit from new music and sound effects’ - Doctor Who Magazine.
