Maryland had many ITV viewers asking the same question before it had even started - is it based on a true story? And the three part drama wraps up on Wednesday night.
ITV has tasted great success with series based on real life events over the past year, with ratings wins from The Thief, His Wife and The Canoe, based on the insurance scam staged by 'canoe man' John Darwin and his wife AnnE, Maxine Peake drama Anne, based on a parent's fight for justice after losing her son in the Hillsborough disaster and, most recently, The Hunt for Raoul Moat, based on the events of summer 2010 and the headline hitting search for killer Moat.
On Sunday night, viewers were gripped by the finale of Malpractice, which while not based on actual events, was heavily inspired by the experiences of former doctor Grace Ofori-Attah, who moved into screenwriting following a 15-year medical career.
