### Premise and format
The series follows DI Max Arnold, the son of a local bookshop owner who was born and bred in Chelsea but is a far cry from the affluent elite whose crimes he investigates. Recently separated from his art dealer wife Astrid ([Anamaria Marinca](https://www.edgepedia.org/anamaria-marinca)), he lives on a battered houseboat at the end of Cheyne Walk while hoping to move back into their apartment in nearby Cadogan Square.[1](https://thebritishtvplace.com/2021/03/the-chelsea-detective-acorn-tv-zdf-commission-uk-mystery-series/) The contrast between his houseboat lifestyle and the affluent neighborhood whose crimes he solves is central to the show's premise.[9](https://www.epguides.com/ChelseaDetective/)
Each season consists of four feature-length episodes of roughly 90 minutes, and each episode is a self-contained murder investigation.[4](https://www.amcglobalmedia.com/2025/08/05/acorn-tv-and-zdf-greenlight-fourth-season-of-gritty-crime-drama-the-chelsea-detective/) Series 1 was originally made as four single episodes of about 90 minutes and has also been broadcast as eight 45-minute two-part episodes.[10](https://www.imdb.com/title/tt14321914/alternateversions/) The official synopsis describes Chelsea as a beautiful borough for beautiful people with a dark underside of deception, violence, greed, and murder, and the detectives must root out the truth no matter the suspects' wealth or status.[11](https://acorn.tv/chelseadetective)
