"Rosemary", who is an ordinary mum and lives in England. She had two children and one died. Her surviving daughter was also her best friend.
Then her daughter joined Scientology and her mother saw less and less of her.
Almost two years ago she received a "disconnect" - a letter cutting her mother out of her life totally.
Rosemary received no Christmas cards, no birthday cards, no Mother's Day cards.
Rosemary said Scientology was a cult. It was one of the most moving and shocking interviews I have ever done.
Out of the blue, three hours after we left, her daughter came round for the first time in almost two years seeking a reconciliation. The next day she begged her mum not to use the interview. So we won't.
[Did they send the daughter round, specifically to kill the interview?]
Scientology is a pay-as-you-go religion - which is one of the reasons why the Charity Commission in Britain does not class it as a religion.
When you have paid as much as £100,000, you get to Operating Thetan Level Three and learn about "The Incident".
L Ron wrote that 75 million years ago an intergalactic space alien lord called Xenu kidnapped Thetans to earth, dumped them in volcanoes and blew them up with atomic bombs.
Ex-Scientologists have insisted to me that Xenu is part of Scientology. If so, it is a religion that requires its followers not to tell others about its core belief, which is very odd.
Critics say that if we all knew about Xenu, then Scientology could not charge people as much as £100,000 to find out about him.
