Nicole Kidman played the lead, Grace Fraser
The six-part HBO series came to an end and revealed Elena's killer as Jonathan Fraser, played by Hugh Grant. After his wife, Grace (played by Nicole Kidman), testified in court, seemingly at first to his defence, many more details unravelled about Jonathan's narcissistic personality disorder, as well as the death of his younger sister – proving his guilt as the assailant.
Jonathan took son Henry and made a run before it, sparking an epic police car chase and the murderer's temper grew more and more manic. Grace came to her son's aid via helicopter, before a dramatic standoff on a bridge in upstate New York. Jonathan was then eventually reprimanded by officers.
