David Clive King was born in Richmond, Surrey in 1924. In 1926 he moved with his parents to Oliver's Farm, Ash, Kent, on the North Downs, alongside which was an abandoned chalk-pit. His early education was at a private infant school where one of the teachers, Miss Brodie, claimed to have taught Christopher Robin Milne, and introduced Clive to stories about Stone Age people. Thereafter he went to King's School, Rochester, Downing College, Cambridge, and the School of Oriental and African Studies, London.

From 1943 to 1947 he served in the Royal Navy, voyaging to Iceland, twice to the Russian Arctic, to India, Sri Lanka, Australia, East Indies, Malaysia and Japan, where he observed the ruins of Hiroshima within months of its destruction. Civilian postings as an officer of the British Council took him to Amsterdam, Belfast, Aleppo, Damascus (styled as Visiting Professor to the University), Beirut, Dhaka and Madras, and gave opportunities for independent travel between these places and England. Several of these exotic places provided material for his nineteen children's stories, but his best-known book STIG OF THE DUMP he wrote in an educational job at Rye, East Sussex. The BBC broadcast a new television adaptation in early 2002.

Married, divorced and married again, Clive King has three children, seven grandchildren and a great-grandchild.

Barney is a solitary 8-year-old, given to wandering off by himself. One day he falls into a disused chalk-pit, landing in a sort of cave, and meets somebody wearing a rabbit-skin and speaking in grunts. He names him Stig, they learn to understand one another and enjoy a series of adventures.
