In 1991 journalists on broadsheet newspapers began to publish stories claiming that Bryn Estyn, a home for adolescent boys on the outskirts of Wrexham, lay at the centre of a network of evil – a paedophile ring whose members included a senior North Wales police officer.

Thousands were accused, hundreds arrested, and the prisons began to fill up with convicted care workers. Had we at last faced up to a horrifying reality? Or was there another, even more disturbing story that remained to be uncovered? Had leading journalists on quality newspapers themselves helped to set in motion a new kind of witch hunt, one that was unable to distinguish between the guilty and the innocent?
