The 6-episode season will debut on Monday, July 12 at 10/9c. - with new episodes being available on streaming service AMC+ a week before their linear debut.
After learning the police investigation into the fatal hit and run of her young son Martie has been dropped, Frances Cairnes (Jumbo) takes matters into her own hands. Posing as a novelist researching a new murder-mystery, she ingratiates herself with the family of George Rattery (Harris), the man she suspects is responsible, and sets a plan in action to kill him. She's tracked by Detective Nigel Strangeways (Billy Howle), who has reason to believe his department covered by George's involvement in the incident. Suffering from PTSD following the recent death of his partner, Strangeways throws himself into pursuing justice for Martie. But when he discovers an "undercover" Frances living with George and his family, Strangeways finds himself working to both prove George's guilt and head off Frances' plans for revenge before anyone else dies.
The cast also features Geraldine James, Nathaniel Parker, Maeve Dermody, Douggie McMeekin, Mia Tomlinson and Barney Sayburn.
Gaby Chiappe created the drama based on the novel by Nicholas Blake. She executive produces with Emma Broughton, David W. Zucker, Nathaniel Parker, Marina Brackenbury, Ed Rubin and director Dome Karukoski. New Regency Television and Scott Free Productions produce.
