Agatha Christie’s Endless Night Is Coming To Britbox And The BBC

Just when you thought you’d heard every Agatha Christie story worth telling, Endless Night sneaks in with a curse, a house in the countryside, and a chilling reminder that love and obsession often share a bed. The BBC and BritBox have officially announced a brand-new three-part series based on Christie’s 1967 late-career masterpiece, and if that wasn’t enough, Sarah Phelps is back to do what she does best—unleashing Christie’s darker, sharper, bloodier edges.

For fans of British mystery, this is great news. For fans of Christie, it’s basically Christmas. Phelps, who previously adapted And Then There Were None, The Witness For The Prosecution, The ABC Murders, and more for the BBC, returns to adapt Endless Night, a ghost story, a love story, and a psychological thriller all wrapped into one. It’s being produced by Mammoth Screen and Agatha Christie Limited, in co-commission with BritBox International.

Set in 1967, the story follows Michael Rogers, a working-class dreamer who stumbles into the glamorous world of a mysterious designer and becomes obsessed with a luxurious home in the countryside. That home, of course, comes with a legend—and a curse. After marrying the sweet and wealthy Ellie and moving in, the couple begins to wonder if the dark forces lurking in the walls are more than just old stories. As shadows lengthen, so do suspicions. Is it supernatural? Or is something—or someone—playing a much more sinister game?

“It’s a chilling story of love, sex, deceit and death,” says Phelps, “of how far we’ll go to get our heart’s desire and what we’ll do when night falls and the wolves start circling.” So yes, this isn’t your grandmother’s Christie… unless, of course, your grandmother was Dame Agatha herself.

And for Christie’s great-grandson James Prichard, the project is deeply personal. “Endless Night is one of my great grandmother’s best stories,” he said. “It is also one of my father’s personal favourites. It’s an extraordinary feat of writing.” Phelps, he adds, is the perfect writer to bring it back to life.

The series will air on BBC One and BBC iPlayer in the UK and on BritBox in the U.S. and Canada, where audiences have proven their love for Christie again and again. With Towards Zero clocking over six million viewers in the UK and topping BritBox’s charts in the U.S., expectations for Endless Night are, well, sky-high—and fittingly eerie.

Casting has yet to be announced, and filming begins later this year, but the creative team is already stacked. Executive producers include James Prichard (Agatha Christie Limited), Damien Timmer and Rebecca Durbin (Mammoth Screen), Danielle Scott-Haughton (BBC), and Robert Schildhouse (BritBox). Translation: this one’s in very good hands.

With Christie still topping the charts as the best-selling novelist of all time, and Phelps continuing to reimagine her work for a new generation, Endless Night is primed to become your next favorite binge. Just don’t be surprised if you start double-checking your locks—or your heart.

Endless Night will stream on BBC iPlayer and BritBox in 2025. And if you’re not already re-reading the book with the lights on… you will be.
