The Sinner has garnered a huge fan base since it first went to air in 2017, with Jessica Biel's haunted and damaged narrative hooking us from the get go.
When seasons 2 and 3 were subsequently released, the same intrigue and hype surrounded the series.
It's now been confirmed a fourth season is incoming, and it looks to be just as gripping as its predecessors. Oh, and yes, Harry's back giving a new case his investigative best.
Here, a look at what to expect from The Sinner season 4, including the plot, cast and release date.
What is The Sinner season 4 about?
Per Deadline, season four will centre around a new case, with the show's main character Harry Ambrose helping the investigation, despite now being retired.
