Apple TV+ has been riding high on the success of its spy thriller Slow Horses, which recently returned for a sixth season. But while fans wait for the next installment of that show, the streamer is doubling down on another adaptation from the same author. Down Cemetery Road, based on Mick Herron's 2003 novel, has officially added a Sherlock favorite to its growing cast for Season 2.

The murder mystery series, which premiered in 2025 to critical acclaim, follows Zoë Boehm (Emma Thompson) and Sarah Tucker (Ruth Wilson) as they unravel dark secrets in Oxford. The show quickly earned a second-season renewal, and now we know who will be joining the pair when the new episodes arrive.

New Faces for Season 2

Among the exciting additions are British acting stalwarts Martin Clunes (Doc Martin) and Amanda Abbington, best known for her role as Mary Watson in Sherlock. They'll be joined by a talented ensemble including Fionn Whitehead (Dunkirk), Paterson Joseph (Peep Show), Aasiya Shah (Raised by Wolves), Dimitri Leonidas (Foundation), Paul Chahidi (This Country), Liz White (Life on Mars), Jeff Rawle (Harry Potter and the Goblet of Fire), and more.

Morwenna Banks, a writer on Slow Horses, returns as lead writer and executive producer, ensuring continuity with the tone that made the first season so compelling.

What's in Store for Zoë and Sarah?

Season 2 picks up after the dramatic church showdown and the death of Amos (Fehinti Balogun). While Zoë and Sarah might think they've earned a breather, the chaos is just beginning. When a woman falls in front of a train, the pair are drawn into "the glamorous but ruthless world of black market antiquities." Expect more twists, tension, and dark humor as they navigate this dangerous new case.

Returning alongside Thompson and Wilson are Joshua James, Sarah Kesstleman, and Tom Riley, so fans can look forward to seeing familiar faces in new predicaments.

While Slow Horses continues to dominate Apple TV's streaming charts, Down Cemetery Road is shaping up to be a worthy companion piece. The show's blend of mystery and character-driven storytelling has struck a chord, and with this stellar new cast, Season 2 is poised to be even more gripping.

For those who can't get enough of Apple TV's original programming, the streamer has plenty more on the horizon, including the upcoming Neuromancer adaptation and the recently renewed Maximum Pleasure Guaranteed. But for now, all eyes are on Down Cemetery Road and its promise of more Herron-inspired intrigue.

Stay tuned for a release date and more details as they emerge. This is one mystery you won't want to miss.
