Episode 2

The hunt for Sian O'Callaghan continues as Det Supt Steve Fulcher and his team see suspects come and go with no leads to follow. Local woman Karen Edwards notices that she only lives a few doors away from the missing girl's mother, Elaine Pickford, but is only reminded of her own problems, having not seen her daughter Becky for several years. With things looking bleak for Wiltshire police, a brilliant piece of police work finally points Fulcher towards a definite suspect.
