The Investigator: A British Crime Story - Season 2

Mark Williams-Thomas returns to ITV for an explosive and ground-breaking new series of The Investigator: A British Crime Story, showing how real life crime can be far more compelling than fiction.

In this three-part series Williams-Thomas, the award-winning former police detective who unmasked Jimmy Savile as the UK's most notorious paedophile, digs into several infamous missing women and unsolved murder cases, uncovering new evidence that links them to two of Britain's most notorious killers - Peter Tobin and Angus Sinclair.

He opens his investigation by exploring the case of Louise Kay, an 18-year-old who disappeared from Eastbourne, East Sussex, in 1988 along with her distinctive Ford Fiesta, after her family asks for his help. The story takes a sinister turn as he uncovers the cases of other women who vanished in similar circumstances and the true scale of the number of missing women and unsolved murder cases across the country emerges.

He also investigates the unsolved murders of Anna Kenny, Agnes Cooney and Hilda McAuley - who were all abducted and killed with four months of each other in Glasgow in 1977.

He goes on the trail of his two prime suspects Tobin and Sinclair and there is a series of revelations about the notorious killers. Both killers, now old men, are serving life for murder. But police believe they have killed more women and Williams-Thomas seeks answers for their suspected victims' families before it's too late.
