Claire Foy (The Crown) is to star in Marlow, a new crime thriller series from the BritBox U.K. streaming service, reports Variety.

Foy will also serve as an executive producer on the eight-part series, which follows two feuding families living in the Thames Estuary, a region east of London where the River Thames meets the North Sea.

She will play Evie Wyatt, a woman who returns to the so-called 'Edgelands' region 15 years after her father was killed in a firestorm there. She's then drawn into her family's longtime dispute with the Marlow clan.

The series, created by Tony Grisoni (Southcliffe, Red Riding) and Simon Maxwell (Deep State), is due to start shooting this fall.

Foy said in a statement obtained by Variety: "I'm delighted to be a part of this compelling thriller. Tony and Simon’s scripts are so evocative of place and redolent with atmosphere — and the twists, turns and mysteries at the heart of this drama are utterly gripping. Evie Wyatt is such a captivating, complex and beguiling character, much like the enigmatic ‘Edgelands’ which she calls home, and I can’t wait to get to step into her shoes."

Grisoni and Maxwell added: "The Thames Estuary’s ‘Edgelands’ offer a unique and extraordinary world of mud, sea and infinite sky; of broken politics and dreams — the Thames mouth is at once a gateway to the world and the last wild frontier of our island existence.

"Marlow is a uniquely homegrown saga, a character driven crime epic about where we’ve come from; who we are now; what we might become. We are thrilled to be working with the extraordinary talents of Claire Foy and, as the home for the boldest new British drama, BritBox is the perfect home for our show."

Foy has also recently signed up to star opposite Paul Bettany in the BBC miniseries A Very British Scandal.
