Who’s the couple?
London housewife Hannah Reilly and her financier husband, Mark.
What’s their story?
When Mark fails to return home from a New York business trip, Hannah’s illusion of a perfect marriage is gutted.
How good’s the big twist?
Thanks to the novel’s overt Britishness, the twists that ensue are more taut and fraught than manic and frantic. Whitehouse’s tale is paranoia-inducing, especially in its second half, but the author’s well-mannered delivery and pacing keep it from turning into a heart-pounding thriller. B
