The Investigator: A British Crime Story

Mark Williams-Thomas re-investigates the disappearance of Carole Packman. With the help of neighbours and friends, he retraces Carole's last known steps

“This time, I’m combining three roles - investigator, reporter and presenter. That means I’m able to explain and unpick threads of evidence as they unfold for viewers, interview protagonists face-to-face, and make the narrative of the story clear.", said Mark Williams-Thomas. My profile since the Jimmy Savile programme has meant I am approached by people from all over the world to help investigate cases. Some have been unsolved, some have resulted in conviction, and they involve a variety of things - missing people, sexual offences, possible miscarriages of justice, even murders. Yet the reason for every contact is the same - those people want to find out the truth."

Mark Williams-Thomas re-investigates the disappearance of Carole Packman. Mark uncovers a series of letters in which Sam's father speaks for the first time about what happened.

“I have investigated many murders and they all have some strange aspects to them when you start digging," said Mark William-Thomas, “But I have never investigated a case that has so many twists and turns like this one. At times it’s hard to believe it’s a real case and not something out of an Agatha Christie novel."
