Rachel's first job as Sergeant is a historical missing person's case, and her biggest challenge is to hide her contempt for the poor police work that hampered the original investigation. Honouring Gill, Janet keeps quiet about being first choice and instead shares another secret with Rachel; she wants a boyfriend. When Mandy Sweeting's body is discovered, 23 years after she went missing, Rachel's first case as Sergeant takes on huge proportions. Wading through narrow-minded police work and re-interviewing bruised and bereft family members, makes this a particularly challenging case.
