Arriving at Heatherbrae House in the Scottish Highlands, Rowan Caine is thrilled to have obtained a live-in nannying post with a generous salary. Giving Henry James's The Turn of the Screw a 21st-century makeover, the author of The Woman in Cabin 10 follows Rowan as she lives in a house where everyone is under electronic surveillance, and she was left alone for weeks at a time, with no adults around apart from the enigmatic handyman. Shockingly, one of the girls in her charge will wind up dead, and Rowan is arrested. Sure, Rowan lied to obtain the post, and admits her behavior toward the children wasn't always ideal, but she's not guilty—at least not of murder—but somebody is.
