Part police-procedural and part supernatural thriller, The Devil’s Hour is the perfect show to binge if you love solving complicated puzzles and don’t mind being spooked by the occasional jump scare. It’s also co-produced by Steven Moffat, who was the brain behind equally mind-bending thrillers Sherlock (BBC) and Doctor Who.

The six-parter follows social worker Lucy Chambers as she looks after potential victims, a behaviorally challenged son, and a schizophrenic mother—and this is on top of her personal problems, which include bloody hallucinations and waking up every day at exactly 3:33 am, or what she dubs the devil’s hour. There are a lot of moving parts in The Devil’s Hour, but aside from the intricate world-building, it’s the powerful performances from Jessica Raine and Peter Capaldi that truly anchor this ambitious show.
