A chilling exploration of a mother's unspeakable betrayal from the author of Little Face. Sally Thorning is watching the news with her husband when she hears an unexpected name-Mark Bretherick. It's a name she shouldn't know, but last year Sally treated herself to a secret vacation-away from her hectic family life-and met a man. After their brief affair, the two planned to never meet again. But now, Mark's wife and daughter are dead-and the safety of Sally's own family is in doubt. Sophie Hannah established herself as a new master of psychological suspense with her previous novel, Little Face. Now with accomplished prose and a plot guaranteed to keep readers guessing, The Wrong Mother is Hannah's most captivating work yet.
