The Staircase: Everything you need to know about the new true-crime drama starring Sophie Turner

Our appetite for true crime shows is so strong that even when it seems as though a new documentary or drama is arriving each week for us to sink our teeth into, we still want more. And luckily, the gods of entertainment seem to hear our prayers loud and clear, as HBO’s new true-crime drama, The Staircase airs next week, and it’s a story that will leave you cold. 

The HBO series is based on real-life events regarding the novelist Michael Peterson, which has already been the subject of a Netflix docuseries back in 2018, who was accused of murdering his wife Kathleen Peterson in 2001. 


What is The Staircase about?

As we mentioned before, The Staircase as it’s based on one of the most infamous and compelling cases of all time, which has already been the subject of a top-true crime docuseries back in 2018 (some say it actually sparked our love of true crime series). It follows the case of Kathleen Peterson, who was found dead at the bottom of the stairs at her family home in North Carolina in 2001, after suspicions arose that her husband, Michael Peterson, had murdered her and staged her death to look like an accident.

HBO’s version of The Staircase will be an eight-episode adaptation of the previous docuseries, written and executive-produced by Antonio Campos (The Devil All the Time) and Maggie Cohn (American Crime Story). 

Who stars in The Staircase?

Well, it’s a pretty star-studded roster (honestly, to be a fly on the wall at the dressing rooms on set for this one), including, Sophie Turner, best known for her role as Sansa Stark in Game of Thrones. Turner will play the role of Margaret Ratliff, one of Peterson’s adopted daughters.
