The post mortem into the daughter of crime boss Steve Richards reveals that her death isn't a simple suicide – could someone else have been involved? And if so, who? While the violent Richards conducts his own unique brand of investigation, the focus shifts once again when the team discover that despite Kat's confession, she can't have murdered Damon Horsley. The break comes when evidence is uncovered that puts Kyle Finn, who found Horsley's body, in the spotlight, and under questioning he confesses to something truly shocking ‐ but Banks already knows he's lying, the real murderer has been hiding in plain sight all along.
