I don't know how I missed this, because I generally love a bit of Scandi noir, but I just discovered it on catch-up and am totally hooked; it's as dark as they come, has a convoluted plot involving secrets, lies, racism, teenage pregnancy, self-harm and lots of very gruesome murders. The acting and production are superb, and once you get used to the mental agility of switching between Swedish, French and English, it's absolutely gripping. Highly recommended!
