In April 2007, 62-year-old Eunice Spry was sentenced to 14 years in prison for subjecting three children in her care to horrifying physical and mental abuse over the course of two decades.
The judge told the court it was the worst case of child abuse he had heard in his entire career.
While her Gloucestershire home should have been a safe haven for the un-loved, in reality it was a prison in which vulnerable children were beaten with sticks and metal bars, scrubbed viciously with sandpaper and routinely forced to eat lard, bleach, vomit and faeces.
To the outside world, Spry was a Jehovah's Witness who presented herself as a moral pillar in the community but behind closed doors she was a sadistic tyrant who forced the children in her care to live in a war zone.
Now, for the first time, one of her victims - known in the case as 'Child C' - tells the full, shocking truth of what went on in Eunice Spry's house. Now 19 and living in constant pain from the injuries inflicted on him, he is a courageous survivor looking forward to the future.
This is the real story behind the headlines which captured the world.
