The Irregulars is a British supernatural crime drama television series. It focuses on the Baker Street Irregulars, a gang of street children who in canon helped Sherlock Holmes gather evidence for his cases. However, it turns their traditional relationship upside-down, portraying the Irregulars as a "gang of troubled delinquent teens who are manipulated into solving crimes for the sinister Doctor Watson and his mysterious business partner". The series also features supernatural elements, as the Irregulars realize they are up against a dark force that threatens not only London but "potentially the entire world."
The series was written by Oscar-nominated writer Tom Bidwell. In an interview with the BBC Writer's Room, Bidwell described the series as his "dream project", and said he had been pitching it for ten years. The series premiered on Netflix on March 26, 2021, to mixed reviews from critics. A month later, the series was a confirmed to be cancelled after one season.
