Apple TV+ has officially shared the first look at Slow Horses Season 5, confirming a global premiere date of Wednesday, September 24, 2025. The new season will launch with two episodes, followed by weekly releases through October 22. Returning to the shadowy corridors of Slough House, the upcoming chapter promises more of the series’ distinctive mix of cynical wit, compromised espionage, and reluctant heroism.
Gary Oldman reprises his role as Jackson Lamb, the slovenly, sharp-tongued leader of a department filled with disgraced intelligence operatives. Lamb’s team of misfits—banished from MI5’s inner circle for their various professional failures—once again finds itself entangled in a plot that threatens to spiral well beyond their pay grade.
Season 5 adapts London Rules, the fifth installment in Mick Herron’s Slough House novels. This time, the spotlight turns to Roddy Ho, the socially oblivious tech specialist who unexpectedly arrives on the scene with a striking new girlfriend. When a series of unexplained incidents ripple across London, it falls to Lamb’s team to connect the dots, even if their methods remain unorthodox and their personal lives unpolished.
Returning cast members include Kristin Scott Thomas, Jack Lowden, Saskia Reeves, and others, with Nick Mohammed—best known for his role in Ted Lasso—joining the series in a guest capacity. The setting remains a character in itself: Slough House, a grimy office tucked near the Barbican, more evocative of bureaucratic exile than covert operations. Overflowing bins, out-of-date tech, and the lingering scent of failure define the work environment, underscoring the show’s central theme that espionage is often as mundane as it is dangerous.
Oldman’s portrayal of Lamb—a figure equal parts abrasive and astute—continues to ground the series in a unique tone. While Slow Horses rejects the glossy polish of traditional spy dramas, it offers something more grounded: agents shaped by personal missteps, who somehow remain capable of extraordinary action when it matters most.
As Season 5 approaches, the series looks poised to deliver another round of off-kilter spycraft, with enough dysfunction to keep things unpredictable, and just enough competence to get the job done—eventually.
