Sienna Miller gathered her family and closest friends into a room and accused one of them of lying in an attempt to get to the source of newspaper stories which she only later realised came from the hacking of her mobile phone by the News of the World.
In herfirst interview to discuss the settlement of her damages claim with Rupert Murdoch's News International this year, the actress told the Independent how the succession of stories about her private life that appeared in the tabloid between 2005 and 2006 made her increasingly paranoid that she was being betrayed by a member of her inner circle.
Miller, 29, was the first celebrity to bring civil proceedings against the NOTW for the interception of voicemails and her High Court claim led to the disclosure of evidence implying that journalists on the paper other than disgraced royal editor Clive Goodman were involved in phone-hacking. Shortly afterwards, Scotland Yard launched Operation Weeting, its ongoing investigation into the hacking scandal which has led to the arrest of 16 people.
The British actress was paid £100,000 ($197,500) in damages and an unreserved apology from News International in May after it emerged that the targeting of her phone by private investigator Glenn Mulcaire led to her changing her mobile number three times in as many months.
"I sat down with my mother, my best friend, my sister, my boyfriend and said 'someone in this room is lying and selling stories and one of you has got to admit it'," Miller said.
