Coup de Grace (1)

Nikki delivers ground-breaking testimony in the high-profile appeal court case of David Bennetto, a convicted killer who has spent the last six years behind bars for the murder of two gay teenagers. But bitter DI Rachel Klein remains unconvinced that she caused a miscarriage of justice and cannot hide her contempt, especially when another young man is found dead bearing the same hallmarks of the previous murders. Meanwhile, Nikki's professionalism is brought into question due to her increasingly close relationship with lawyer Greg Walker.
