Following a break-in, a frail, elderly woman is found dead in her flat. DS Brooks and DS Casey suspect a robbery gone wrong and treat it as murder. Tipped off by the victim's granddaughter, Connie, the investigation turns towards the live-in carer who has gone missing. But the carer, Cecile, claims she was fired because she disobeyed Connie's instructions not to feed her grandmother. Further investigations throw more suspicion on the granddaughter who is charged. Despite her brief arguing that it is impossible to prove Connie is responsible for her grandmother's death, Chief Prosecutor Thorne has the bit between his teeth when he tells the jury Connie was the only real family the victim had, and she left her to die.
