The series also features Jennifer Saunders (Absolutely Fabulous), Anthony Head (Buffy), Stephen Rea (Greta), and Richard Armitage (North and South).

In the series Siobhan Finneran will play Deputy Sheriff Johanna Griffin, the series is based on the bestselling Harlan Coben novel of the same name and is produced by Red Production Company.

As mentioned earlier, Hannah John-Kamen plays a mysterious stranger who exposes people’s secrets, dropping bombshells that will shatter lives. Jennifer Saunders joins in her first major dramatic role, as Heidi, Johanna’s closest friend; an outgoing character who is seeking adventure after her daughter leaves for university.

The cast also includes Shaun Dooley (Ordinary Lies, Broadchurch), Paul Kaye (Game of Thrones), Dervla Kirwan (Strike Back, Silent Witness), Kadiff Kirwan (Chewing Gum, Black Mirror), Anthony Head (The Split, Buffy The Vampire Slayer) and Oscar-nominated actor Stephen Rea (War and Peace, The Crying Game).

Richard Armitage plays Adam Price, the series’ protagonist who finds himself tangled in a mysterious web of deception. His life seems perfect until The Stranger reveals a shocking secret about his wife.

Siobhan Finneran’s punchy police detective, Johanna Griffin, finds her pragmatic approach to police work compromised when her investigation into the matter becomes deeply personal.

Finneran said: “I am thrilled to be working with RED again – it’s been a brilliant 20-year relationship and I feel very lucky and blessed to have that with them. After the success and utter joy of working on Happy Valley with them, it’s great to now be involved in such a new and exciting project.”

Hannah John-Kamen added: “I’m so excited to be attached to a special project for Netflix that is so thrilling and full of mystique. It’s a real page turner of a show and I’m honoured to be part of it.”

Dervla Kirwan’s character, Corrine Price, is a well-respected teacher, a loving wife to Adam and mother to their two sons. When Adam learns a terrible secret about his wife from The Stranger, he confronts her but she disappears, kick-starting a chain of events with potentially devastating results.

Stephen Rea will take on the role of Martin Rinksy, a retired police detective who still has connections in the field. As Adam turns to him for help, the former policeman is soon forced to confront events from the past.

“The Stranger” is the third collaboration for RED Production Company, Harlan Coben and Netflix, following the success of “The Five” and “Harlan Coben’s Safe,” which starred Michael C. Hall. Nicola Shindler, writers Harlan Coben and Danny Brocklehurst, and Richard Fee are the Executive Producers of the new eight-part series. Madonna Baptiste will produce “The Stranger” with Daniel O’Hara as lead director and Hannah Quinn as second block director.

“The Stranger” is created by Harlan Coben, and is based on his best-selling novel. Filming starts 4 March in and around the UK.
