My cousin Lila rented a tiny cottage near the Brecon Beacons last summer. She moved out after a week, no explanation at first. Turns out she’d woken up at 3 a.m. to a shadowy figure standing by her bed. She wouldn’t talk about it for months. Now I’m seeing this new BBC thriller, The Witch Farm. It’s a four-part supernatural drama set in 1989, about a couple who move to an isolated Welsh farmhouse and spot a ghostly figure in their bedroom. It’s not just creepy. It’s making me rethink writing off her story as sleep deprivation. I’ve already marked my calendar to watch every episode.
