You'll recognise Irish actor Sarah Greene from her role as Connell's mum in the hit BBC3/HBO series Normal People. In Roadkill, Greene plays the newspaper reporter at the centre of Laurence's downfall. When Charmian learns her story on the MP's tax dodging has not only cost the newspaper £1.5 million in damages but her job, too, she resolves to dig deeper and bring to light the truth about the minister's wrongdoings.
