Season 3 of Acorn TV’s captivating hit crimedrama The Chelsea Detective, starring Adrian Scarborough (Killing Eve, The King’s Speech, 1917) and Vanessa Emme (Dublin Murders, Three Families) returns with all-new episodes on Monday, April 7 in the US, Canada, Australia and New Zealand. Season 3’s remaining three episodes will air weekly on the service with SAG(R) Award-winner Alex Kingston (A Discovery of Witches, Doctor Who, ER) guest starring as US Ambassador Emily Morgan in the debut episode, “Deadlock.” The Christmas Special, which serves as the first episode of the 4 x 90 season, premiered in December 2024 and is available to stream on Acorn TV.
The upcoming season sees DI Max Arnold (Scarborough) and DS Layla Walsh (Emme) delve once more into the darker side of Chelsea that lurks beneath its glossy façade. Season 3 finds Max and Layla investigating the discovery of an ex-soldier’s body in an allotment, the brutal murder of an antiques dealer, and the mysterious case of a climate scientist found dead in a stolen car.
But, while Max remains adept at solving crimes, things are far from straightforward at home. After all their ups and downs, Max and his estranged wife, Astrid (Anamaria Marinca, Deadline) are now trying couples therapy in a bid to revive their relationship and unpack where it all went wrong for them.
Sophie Stone (Shetland) returns as the brilliant, if occasionally daunting, Chief Forensics Officer Ashley Wilton, Lucy Phelps (Grace) as research and tech queen DC Jess Lombard, Peter Bankolé (Peaky Blinders) as officer DC Connor Pollock, along with Frances Barber (Whitstable Pearl) as Max’s Aunt Olivia who remains as full of joie de vivre as ever. With three new thrilling cases taking the team from intrepid mudlarks on the Thames foreshore to the formidable power of the US Embassy, the all-new season presents the team with their toughest challenges yet.
