What is the name of J.K. Rowling’s adult crime-fiction detective?

J.K. Rowling’s adult crime-fiction detective is Cormoran Strike.

Rowling writes the Cormoran Strike novels under the pseudonym Robert Galbraith. Strike is a private detective in London and a former military police investigator. His professional and personal partnership with Robin Ellacott forms the central relationship across the series, combining investigations with continuing character development.

The first novel, The Cuckoo’s Calling, was published in 2013 and initially credited to Robert Galbraith. The pseudonym’s identity was later revealed as Rowling. The books are separate from the Harry Potter universe and use the conventions of modern detective fiction rather than children’s fantasy.

Cormoran Strike is sometimes confused with characters from other British or international crime series because he is a private investigator rather than a police detective. His full name is Cormoran Blue Strike, but “Cormoran Strike” is the canonical name used for the series and its title character.
