British crime author Mick Herron is rapidly establishing himself as a foundational creative force for Apple TV+, with his unique blend of mordant wit and intricate plots translating into critically acclaimed dramas. Following the success of the Emmy-winning “Slow Horses,” an adaptation of his Slough House series, Apple TV+ is now expanding Herron's television universe with “Down Cemetery Road,” based on his debut novel and the beginning of another four-book series.

“Slow Horses” has carved out a distinct niche as an unlikely franchise, chronicling the misadventures of a group of disgraced MI5 agents led by the irascible, flatulent Jackson Lamb, brilliantly portrayed by Gary Oldman. This espionage thriller has broken out of the streamer's typical offerings, achieving broad cultural recognition and promising years of content given Herron's prolific output.

The new eight-episode series, “Down Cemetery Road,” developed by “Slow Horses” writer Morwenna Banks, demonstrates that Herron's distinctive sensibility can successfully migrate from the gritty streets of central London to the more serene, yet deceptively complex, backdrop of middle-class Oxford. While sharing recognizable DNA with its sibling show, it swaps covert missions for cul-de-sacs, focusing on a domestic mystery rather than international intrigue.

Emma Thompson takes on a rare television role as private investigator Zoë Boehm, a misanthropic character whose abrasive bedside manner echoes Jackson Lamb's, while her androgynous style recalls Diana Taverner, the icy intelligence chief from “Slow Horses.” Joining her is Ruth Wilson as Sarah, an art conservator whose life unravels after a sudden explosion disrupts a dinner party near her affluent Oxford home, killing two people and injuring a young girl.

The central mystery unfolds when Sarah, driven by an unshakeable instinct that something is terribly wrong, enlists Zoë and her estranged husband Joe (Adam Godley) to find a child she saw earlier that day – a child who is now missing and whose disappearance the police dismiss as unrelated to a simple gas leak. What begins as a search for answers concerning a neighborhood tragedy swiftly escalates into a far wider and murkier web of conspiracies, ultimately hinting at a massive government cover-up.

Wilson's portrayal of Sarah is a frantic, increasingly on-tilt performance, as her character struggles to reconcile her polished “Farrow & Ball life” with her compulsion to uncover the truth, even for a stranger. Zoë, in contrast, deals with her emotions by repressing them beneath Thompson's snappy assertiveness, throwing herself into the investigation. The combative chemistry between Wilson and Thompson, though selectively doled out until later episodes, is a highlight of the series.

Herron's signature tone, characterized by a balance of humor without being glib and darkness without being grim, translates effortlessly to “Down Cemetery Road.” The series delves into themes of guilt, secrecy, and the quiet absurdity of English life, painting a world where manicured lawns and symmetrical houses hide deceptive surfaces, making every crack in the facade land with impact. Visually, director Natalie Bailey captures Oxford's seemingly tidy appearance while subtly revealing its imperfections, mirroring Sarah's own fixation with restoration.

While “Down Cemetery Road” may not possess the “drum-tight concision” of “Slow Horses,” its deliberate, slow-burning pace effectively builds paranoia and mystery. The writing, also by Morwenna Banks, trusts the viewer to sit in the unease, allowing every episode to serve as a progression toward a deeper conspiracy. The series is equally well-acted and well-observed, featuring a tight supporting cast including Adeel Akhtar as a nervous bureaucrat, Darren Boyd as a charmingly sinister government man, and Fehinti Balogun as an unnervingly calm assassin.

Ultimately, “Down Cemetery Road” is a smart, stylish, and shadowy thriller that doesn't aim to be a mere replication of “Slow Horses.” Instead, it carves its own identity, exploring the impact of Herron's morally gray worlds within suburban settings, where secrets are loaded into every silence. With compelling performances from Thompson and Wilson, it offers plenty to satisfy fans of Herron's unique brand of twisted mystery. The series premieres with two episodes on October 29 on Apple TV+, followed by new episodes every Wednesday.
