Barry Hines's A Kestrel for a Knave, published in 1968, was made into one of the key British films of the sixties. Billy Casper is beaten by his drunken brother, ignored by his mother and failing at school. He seems destined for a hard, miserable life down the pits, but for a brief time, he finds one pleasure in life: a wild kestrel that he has raised and tamed himself.
