The Phantom Social Worker: Britain's Most Disturbing Unsolved Mystery... | Conspiracy Theories

Throughout the nineteen-eighties and nineties, families across Britain reported visits from a mysterious woman claiming to be a social worker — always well-dressed, always carrying a clipboard, always asking to speak with children alone.

Tonight on Sleep Theories, we follow investigative journalist Daniel Harper as he digs through archived police reports, missing government files, and a chilling off-the-record disclosure from a retired social services employee — uncovering a case that authorities called a misunderstanding, but that thousands of families could never forget.
