Эпизод 2

The detectives investigate when a young woman is fished out of the Thames in the middle of the night, badly burnt and barely alive, with the only witnesses at the scene being a few homeless people who saw a man with a white van dumping the body in the river. Charlie runs the victim's distinctive necklace through the database and links it to Sian Jenkins, who was registered as missing in 2012, and events take a further turn when DNA taken from under her fingernails is matched to a girl who disappeared when she was eight almost a decade previously.
