Acorn TV and its co-production partners announced today that filming has started on Season 4 of the viewer-favorite mystery series, The Chelsea Detective. (Hooray!)
I adore The Chelsea Detective, so I’m stoked that it’s returning with a fourth season.
Filming for the upcoming season is already happening in and around London, with series leads Adrian Scarborough (Killing Eve, The King’s Speech, 1917) and Vanessa Emme (Dublin Murders, Three Families) returning as Detective Inspector Max Arnold and Detective Sergeant Layla Walsh, respectively.
Also reprising their roles are Sophie Stone (Shetland) as Chief Forensics Officer Ashley Wilton, Lucy Phelps (Grace) as research and tech queen DC Jess Lombard, and Peter Bankolé (Peaky Blinders) as officer DC Connor Pollock, along with Frances Barber (Whitstable Pearl) as Max’s Aunt Olivia.
Season 4 consists of four feature-length episodes and sees Max and Layla tackle a new murder mystery in each of them. Set within the elite world of Chelsea, the duo and their team investigate crimes related to a fashion mogul sinking fast in the trappings of her wealth; an aristocratic dynasty guarding their bloodline with brutal devotion; and a wellness and beauty salon owner concealing lethal truths. This season also features a cryptic double-murder that begins in Chelsea and spirals outward, drawing the team into the cutthroat world of architecture. Meanwhile, a hint of romance is in the air for Max…
The Chelsea Detective is created and executive produced by Emmy® Award winner Peter Fincham (The Lost Prince, Smack the Pony, I’m Alan Partridge) and produced by Ella Kelly (Death in Paradise, Midsomer Murders). Season 4 episodes are written by Fincham, Glen Laker (Vera), and Liz Lake (The Mallorca Files). The directors are Richard Signy (Death in Paradise) and Audrey Cooke (Agatha Raisin).
The series is a production of Acorn TV’s Acorn Media Enterprises, Germany’s ZDF, and the BBC Studios-invested indie Expectation, with Acorn TV serving as the exclusive home for the series in the US, Canada, Australia, and New Zealand. BBC Studios is handling global sales.
The Chelsea Detective: Season 4, an Acorn Original Series, will premiere on Acorn TV in 2026. Stay tuned for updates.
