There’s something quintessentially British about this four-part psychological/supernatural thriller, and not only because it stars Bertie Carvel (Doctor Foster) looking like Charles Dickens’ Fagin.
All lank hair, grubby overcoat and New Age jewellery, he’s Bob Morrow, a self-professed expert in the paranormal, who turns up unannounced on the doorstep of Nathan (Russell Tovey, last seen in Years and Years). It’s not immediately clear what connects Bob with clean-cut Nathan and his exquisitely decorated home, but it’s apparent it isn’t something pleasant.
The Sister, written by author Neil Cross, creator of hit crime series Luther (and based on his 2009 novel Burial), unravels across several different years; time jumps around, but it’s well-signposted and does, ultimately, make sense. Before Nathan opens the door to Bob in the present day, we’ve briefly seen him in 2013, contemplating ended it all until he sees a news item in which a woman makes a plea for information about her missing sister, Elise (Sex Education’s Simone Ashley). That woman is Holly Fox (Game of Thrones’ Amrita Acharia), who, it now transpires, is Nathan’s wife. (The scene in which he contrives to meet Holly, and their first date, is almost as unnerving as the ghostly goings on.)
This shocks Bob, too, who, seeing photos in Nathan’s hallway, looks aghast. “What have you done, Nathan?” he asks, before telling him that the pair need to act fast as “they’re digging up the woods”.
