Question: is the show the sinner based on a true story

Answer: No, The series, described as a ``close-ended series'' by the network, was adapted from the novel of the same name by Petra Hammesfahr; however, the book's darker outlook was toned down and the location shifted from Germany to Upstate New York in the United States. It was the first time that Biel had executive-produced a series, a role she said was ``gold''. Biel stated that she moved into production so that she could develop projects with challenging and interesting roles rather than wait for them to happen.
