Nicholas Fisk (1923–2016) is a half-forgotten name now, and his memoir Pig Ignorant is a wholly forgotten book. It deserves not to be, and he deserves not to be. Fisk was a bestselling children’s writer through my own ’70s and ’80s childhood and was described by one critic as ‘the Huxley-Wyndham-Golding of children’s literature’. But if he is remembered now, it’s for his science fiction and only vaguely, and only by people about my age. There’s the Bradburyesque alien invasion horror Grinny (see SF no.78) and its sequel You Remember Me , the disconcerting genetic-engineering story A Rag, a Bone and a Hank of Hair , and Trillions , in which tiny, collectively intelligent alien particles fall to earth like snow. In his most memorable stories the surface appearance of the world masks something darker and stranger. There’s a world behind the world.
