|Here is another entry in Pratchett's fabulously successful, entertaining, funny and insightful Discworld series. As the great space turtle, Atuin, carries the disc through the universe, three witches on it become involved with local politics when a mad duke assassinates the good king, whose son escapes. There are ghosts, magic, time stoppage, dwarves and great fun. An interesting device has another reader portraying Death in an echoing, resonant male voice. Overall, narration is done by Celia Imrie, who reads distinctly and slowly, changing accent and pacing to distinguish the characters. Some oddly effective alien music punctuates the sides of the cassettes.
