Barry Hines, the Yorkshire author who wrote the novel on which Ken Loach's film Kes was based, has died aged 76. The news was announced on Twitter by the poet Ian McMillan and subsequently confirmed by a friend of the author. Born in a mining village near Barnsley, Hines also wrote Threads, a 1984 BBC film that dramatised the effects of a nuclear strike on Sheffield. Hines, who collaborated with Loach on a number of other projects, was diagnosed with Alzheimer's disease in 2009. Hines, who was born in Hoyland Common in 1939, left school without qualifications but later returned to complete his education. He went on to become a teacher before turning to writing and publishing his first novel, The Blinder, in 1966. His second novel - A Kestrel for a Knave - about a young working-class boy named Billy who finds and trains a kestrel, was published in 1968 and filmed the following year. Who could forget that film?
