The proceeds from his 2019 memoirs Behind the Staircase and Beyond the Staircase have been donated to charity.
HBO’s new true-crime drama, The Staircase, tells the story of Michael Peterson, the American novelist who was convicted of killing his wife Kathleen, despite maintaining she had died after falling down the stairs.
The Staircase is out on HBO Max and Sky Atlantic on Thursday 5 May.
The first documentary was released in 2004, with new episodes being added to cover more recent developments in 2013 and 2018.
