WATCH: The new trailer for The Sinner Season Two has completely creeped us out

Everyone knows who did it, but nobody knows why.

When the first season for The Sinner was released, it was all anyone could talk about. Starring Jessica Biel as the woman who very clearly murdered someone, but with no memory of doing it, it also featured Bill Pullman as the investigator attempting to get to the truth of it all. It was a fantastically dark and twisted murder-mystery, and we absolutely loved it, which is why we're more than happy to see that Season Two is only a few weeks ago. Pullman returns as the detective, this time looking into the case of a double-homicide, one which was performed by an 11-year-old boy, who seems to have murdered his parents without cause. Pullman will be joined by a new co-lead, played by Carrie Coon (The Leftovers, Fargo, Gone Girl), and it appears she'll be causing just as much trouble as Biel did last time around. Biel herself won't be returning in front of the cameras this time around, but she remains on-board as an executive producer, and has released the latest trailer via her Twitter account, which you can check out below. The new story will kick off Stateside on Wednesday 1 August, and while there is no Ireland and UK release date yet, we imagine Netflix will pick up the rights to stream all episodes once the series has completed it's run in the USA. https://twitter.com/JessicaBiel/status/1007336642049335296
