The two-part thriller follows Mark Easterbrook (Rufus Sewell) as he investigates a mysterious list of names discovered in a dead woman’s shoe.

Easterbrook’s search for answers leads him to the unusual village of Much Deeping and The Pale Horse, the home to a group of suspected witches.

Rumours have circulated the town that the witches are responsible for the disappearances of wealthy relatives using dark magic yet Easterbrook remains adamant that there are rational explanations to solve these mysteries.

The trio of witches will be played by Rita Tushingham (A Taste Of Honey) as Bella, Sheila Atim (Girl From The North Country) as Thryza Grey and Kathy Kiera Clarke (Derry Girls) as Sybil Stamford.

"We are thrilled that filming is now underway on The Pale Horse for BBC One,” said Tommy Bulfin, BBC Drama Commissioning Editor.

“Sarah’s brilliant scripts and her unique take on the famous Agatha Christie stories have once again attracted an array of top and exciting talent."

Also among the cast is Kaya Scodelario (Crawl) as Hermia, Bertie Carvel (Doctor Foster) playing Zachariah Osborne, Sean Pertwee (Gotham) as Detective Inspector Lejeune, Henry Lloyd-Hughes (Killing Eve) playing David Ardingly, Poppy Gilbert (Call The Midwife) as Thomasina Tuckerton, Madeleine Bowyer (Black Mirror) playing Jessie Davis and Ellen Robertson (Snowflake) as Poppy.

Mammoth Screen and Agatha Christie Limited will produce the series, with the latter’s executive producer and CEO, James Prichard, commenting: “This adaptation feels like nothing we have done before.”

“This is a very different story from most that my great-grandmother wrote, and Sarah has taken it to new heights,” he added.

"Sarah Phelps has excelled herself with her fifth adaptation of Agatha Christie’s work,” commented Helen Ziegler, Executive Producer for Mammoth Screen.

“The Pale Horse is a stunningly atmospheric, bewitching and thrilling piece, which has attracted the most wonderful stellar cast.”
