S1·E2 Daddy's Little Girl

DI Vivien Friend investigates the murder of a young woman whose remains have been found preserved in a concrete tomb at a demolition site. The only clues to her identity are a healed scar along her left hand and a puncture mark at the base of her spine from a medical procedure.

The police investigation leads to a 3 year old missing persons case in which a young girl vanished from her parents' pub without trace. When the autopsy confirms it is the same missing girl, DI Friend has to break the news of her death to her distraught parents Celia and Phil Seabrook. The strongest lead is a mysterious photograph of their daughter with an unidentified man, and when the pathologist reveals their child Lucy was in the early stages of a pregnancy, the race is on to find him.
