Mortal

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, and that Connie was starving her to death.
