British Mystery · Acorn TV / ZDF · 2022–present
The Chelsea Detective
Adrian Scarborough stars as DI Max Arnold, a dyslexic, piano-playing detective who investigates murders among London's wealthy Chelsea set while living modestly aboard a battered houseboat on the Thames — a deliberate contrast the show returns to again and again. Each season tells four self-contained, feature-length cases, with Max's own family life, including his separation from wife Astrid, running quietly alongside the weekly mysteries. The Chelsea Detective streams on Acorn TV in the US.
Is This Series for You?
Fans of Slow-Burn, Character-First London Mystery
Viewers who like their detective grounded and understated, with the contrast between a wealthy setting and a modest, personal lead character doing a lot of the show's storytelling work.
Four Feature-Length Cases Per Season
Each season is an anthology of four standalone, feature-length mysteries rather than a single ongoing arc, making individual episodes easy to pick up.
Rated 12, Moderate Content
The show includes mature themes and murder investigations but avoids excessive violence or graphic content. British TV Hub's verdict: a quietly confident, well-cast mystery that rewards patience over flash.

What Makes the Series Special
Wealth Versus a Battered Houseboat
The show's core visual and thematic hook is the gap between Chelsea's affluent world and Max's own modest houseboat life on Cheyne Walk, used again and again to sharpen its social commentary.
Adrian Scarborough's Understated Lead
Known for Killing Eve and The King's Speech, Scarborough brings a relatable, unshowy quality to Max Arnold that anchors the show's quieter, more introspective tone.
Standalone Cases, Consistent Characters
The anthology-style, four-episode-per-season format lets new viewers jump in at nearly any point while still rewarding longtime fans with Max's evolving personal storylines.
Setting and Filming Locations
Chelsea, London
The Chelsea Detective is set in and around the wealthy London borough of Chelsea, with Max's houseboat moored along the real Cheyne Walk on the Thames, contrasting sharply with the grand properties his cases take him into.
