Based on a bestseller, The Serial Killer’s Wife is now going to be a series on Paramount Plus starring The Split’s Annabel Scholey as Beth Fairchild, a woman whose idyllic world falls apart when her husband is arrested for murder. 

This suspense-packed thriller series also stars Jack Farthing as Beth’s seemingly straight-laced husband Tom, while Luke Treadaway is Tom’s best friend and Beth’s confidant, Adam.
