Three Girls is a three-part British television drama series, written by screenwriter Nicole Taylor, and directed by Philippa Lowthorpe, that broadcast on three consecutive nights between 16 and 18 May 2017 on BBC One.
 A co-production between BBC Studios and Studio Lambert, the series is a dramatised version of the events surrounding the Rochdale child sex abuse ring, and describes how the authorities failed to investigate allegations of rape because the victims were perceived as unreliable witnesses.
 The story is told from the viewpoint of three of the victims: fourteen-year-old Holly Winshaw (Molly Windsor), sixteen-year-old Amber Bowen (Ria Zmitrowicz) and her younger sister Ruby (Liv Hill); although the focus later shifts to sexual health worker Sara Rowbotham (Maxine Peake), who became the main whistleblower who drew attention to the case after repeated pleas for help from social services and the police fell on deaf ears.

Question: Who wrote the three-part 2017 British television drama series about a child sex abuse ring involving 47 under-age teenage girls in Rochdale, Greater Manchester, England?
Answer: Nicole Taylor
