The Butcher Boy by Patrick Mccabe

A modern classic of Irish fiction, shortlisted for the 1992 Booker prize.
When I was a young lad twenty or thirty or forty years ago I lived in a small town where they were all after me on account of what I done on Mrs Nugent.
Francie Brady is a small-town rascal who spends his days turning a blind eye to the troubles at home and getting up to mischief with his best friend Joe – hiding in the chicken-house, shouting abuse at fish in the local stream. But after a disagreement with his neighbour Mrs Nugent over her son's missing comic books, Francie's reckless streak spirals out of control and gives rise to a monstrous obsession . . .
