The police investigate Emily's death, while flashbacks show how her behaviour grew

ever more erratic in the time leading up to her murder. A series of revelations about

the eight-year-old girl reveal how she drove her family to despair by abducting her

baby sister and making thinly veiled accusations of abuse against step brother Jack.

Emily's accusations against Jack threaten to tear Cameron and Sue's relationship apart

as they argue over how to deal with the teenager, who in turn falls into Mary's arms.

Cameron eventually turns to Polly for a sympathetic ear, while Anne decides to book a

holiday to escape her problems.
