In the spring of 1990, families across Britain began reporting visits from strangers claiming to be social workers.  They spoke with authority, carried clipboards, even asked to photograph or examine children — and then vanished. Police launched Operation Childcare, a nationwide manhunt involving more than twenty forces, but no arrests were ever made. Were these criminals, insiders, or the product of a moral panic born from fear and mistrust? Join John Williamson by the fireside as we unravel one of the strangest unsolved mysteries of late-20th-century Britain — a story where rumor met authority, and where fear itself became the evidence.     📚 Verified Sources & Further Reading   Primary & Contemporaneous Reporting The Guardian (1990 – 1991) – National coverage of “bogus social workers” investigations.
