This is an account of the trial of three policeman involved in the Guildford Four case. They were acquitted, but Bennett's essay, which was originally published in an abbreviated form in "The London Review of Books", highlights many disquieting aspects of the case. In particular, he recounts his own experiences as somebody who was once charged with murder - and subsequently acquitted - in Belfast, to show why prisoners confess to crimes they haven't committed.
