‘The Catholic religion teaches us that redemption is possible, that even the greatest sinner – even someone who has tortured and killed children for the obscene pleasure of it – can be washed clean of their guilt. Evil is a noun, something like dirt inside you. But for most of us, evil is more like a verb: something you do, not something you are. This is the more modern and more terrifying view of our moral universe – because, instead of regarding Hindley as simply monstrous or aberrant, ‘possessed’, as it were, by evil, we have to start seeing her as not so very different from all of us, just someone who made different choices. She is not alien, but human. This is what humans can do, if they take the hellish road and step by step go down it.’

‘Ever the fantasist, Barry George may now be adapting to his notoriety (two tabloid newspapers have advertised tapes of prison “confessions”), but he should be a footnote in this story. Apart from that invisible speck of explosives residue found on his coat, the police found no evidence that he had possessed guns or ammunition in the past 15 years. He had neither expertise in weapons, nor the resources to modify them. He had no car, no money. There was no forensic evidence found in his flat: remarkably, police found no explosives residue there, even though it was assumed that he’d gone home to change straight after the shooting. The two squads of officers, 50 in all, who surveilled his movements for more than three weeks before his arrest gleaned no evidence to assist their case. Dando’s neighbours, the only two eyewitnesses, failed to pick out George in an identity parade.’
